the TQGs. Each M46 kit consists of drop boxes with standard electrical duplex receptacles, branch cables for connecting and stringing up the drop boxes, and extension cables that run from the PDISE to the branch cables. In general, two M46s are

issued with each M40. They can also be connected to the small A connectors on the

3.3.2 General Guidelines for Setup 3.3.2.1 Power Plant Setup

Setup and grounding of each TQG is covered in the for that TQG. THE TQGS MUST BE GROUNDED PRIOR TO STARTUP!

Each PP consists of an A and a B unit. The A unit has the switch box. The B unit has the power cable. Each PP has two paralleling cables, one for each generator. On the MJQ-40 , and MJQ-48, they are stored inside the rear doors, along with the auxiliary fuel hose. Remove the cables from storage and install using the following steps:

Connect one end of the paralleling cable to connector J3 on the switch box located on unit A. Route the other end of this cable through the power cable sock and connect to connector

on unit B. The receptacle is found inside the load terminal area in the far upper left corner. This provides power to the switch box. This connection can be difficult to secure;

the cable has to seat properly the switch to work.

2. Connect the second paralleling cable between the two paralleling receptacles on the generator set control panels.

This allows the TQGs to "talk" to each other.

3. Once these two cables are connected, ensure they do not form an X. If they do, the cables are connected incorrectly.

4. Unwrap the power cable from around unit B, but do not disconnect it from the unit B. Connect the plug end of the power cable to port J2 of the switch on A. Route the other end of the cable through the power cable sock and connect leads to appropriate load terminals on unit B. Leads will be labeled with load terminal designations.

3.3.2.2 Connecting to PPs

Each is supplied with two 25-ft feeder cables and one 4-ft pigtail used to connect the to the power plant.

Each power plant has a switch that combines the power produced by the TQGs, and provides a safe, common connection point. The power is taken off the switch box through the terminal lugs found on the side of the switch box.

The pigtail from the connects to the switch box terminal lugs. The marking on the switch box (G, N, L2, L3) matches the marking on the pigtail. The wires are also color coded:

1) Green = ground = G 2) White = neutral = N or LO 3) Black = Phase A = L1

4) Red = Phase B = L2

5) Orange or Blue = Phase C = L3

Pigtail Cable

The two long cables connect between the pigtail and the These enable the to move the PP away from the TOC, and reposition the as needed.

3.3.2.3 Connecting Shelters to

Each shelter mounted on a HMMWV has one 50-ft cable and one pigtail, both rated 60 A. Prior to connecting anything to the ensure the connector to be used is not ON. This is done by switching the appropriate circuit breaker into the OFF position.

For the CPP and ADAM shelters, use the 50-foot vehicle cable to connect from the J1 port on the power entry panel to a 60-A rated port on the (J3 or J6). Other shelters (such as DTSS) can use J4 or J5 on the After the cable is connected, close the appropriate circuit breaker.

Ensure shelter power requirement of 40 or 60 A prior to connecting power. See Figure 3-83.

3.3.2.4 PDISE: M40, M46

The M40 PDISE boxes are used in conjunction with the M46 electrical distribution kit to provide a place to plug in electrical and electronic equipment. Use the large feeder cables that come with the M40. Connect the cables to the J1 port on the M40 and a port rated for 40 A on the (J4 or J5; Figure 3-84).

Figure 3-83 Connections

Figure 3-84 M40 Connections

The M40 receives 3-phase power and splits each phase to separate connectors. On each side of the M40 are two connectors for each phase. These connectors alternate A corresponds to L1 on the TQG, B corresponds to L2, and C corresponds to L3.

When connecting the M46 cables to the M40, use groups of three connectors. This keeps the total load balanced on the generator, and prevents overloading any one phase. Use the C connector first, then B, then A, and then repeat as needed.

The M46 branch is one line with three outlet boxes. Each box has four outlets. The entire line is connected to one 20-A circuit breaker. When connecting, go in numerical order, i.e., J3, then J4, then J5. This ensures each phase gets loaded, and that C is guaranteed a load. The items that are connected to each branch are METT-TC dependent.

3.3.3 General Operation 3.3.3.1 Start and Parallel PPs

Start one generator and apply load as per the TQG operation instructions. To parallel the TQGs or transfer load from one to the other, follow the instructions below. These instructions are also on the inside of the switch box control panel door.

For detailed instructions and diagrams, refer to the PP TM.

• To start the MJQ-48: the DEAD CRANK switch must be in the NORMAL position, the DC Control Power circuit breaker must be pushed in, and the Emergency Stop Switch must be in the OUT position. Move the MASTER SWITCH to the START position and HOLD until the frequency gauge reads 60 Hz, the voltage gauge reads 120 volts, and oil pressure is at 60 psi. Once the generator set is running, move the AC CIRCUIT INTERRUPTER switch to the CLOSED position to supply power to the load. If the generator set's STATUS light is on, move the ON/OFF switch at the switch box to the ON position to supply power to the load.

Use to following steps to parallel the MJQ-48. Gen 1 is the generator that is on; Gen 2 is the generator that is off.

Start the vehicle engine to supply power to the shelter equipment (except the ECU), while transferring power to the TQGs.

3.3.3.2 Use the following steps to switch from on-board power to import power:

an APU is installed in the shelter, turn off APU and remove the feeder cable at the J1 import connector of the shelter's Power Entry Panel (PEP). BEFORE CONNECTING THE CABLE AT THE MAKE SURE THE CIRCUIT BREAKER ASSOCIATED WITH THE CONNECTOR IS TURNED OFF!

2. Connect the 50-ft, 60-A feeder cable supplied with the CPP from a 60-A rated port on the (J3 or J6) to the J1 Import connector on the CPP's PEP.

3. Wth the connections made, first turn the circuit breaker at the to the ON position, and then turn the IMPORT POWER circuit breaker and the DC POWER SUPPLY circuit breaker at the shelter's PEP to the ON position.

4. To verify power at the PEP, press the PUSH TO TEST button and the three PWR SUPPLY AC and PWR SUPPLY DC OUTPUT LEDs should illuminate.

3.3.4 PDISE Placement - General Guidance 3.3.4.1 BDE Main, BSB

The BDE HHC Main TOC uses one MJQ-41 as the primary power source. The BSB TOC uses one MJQ-40 as the primary power source. Figure 3-83 shows a suggested layout the BDE Main based on the TRADOC-designed TOC configuration. After the TOC tents are set up, place the M40s so there is one M40 for about every two TMSS tents (the exception is the which may need its own M40).

Then place each within 50 ft of two shelters and one of the M40s. Keep the number of items connected to the

balanced. This helps prevent overloading and tripping circuit breakers. At the BDE Headquarters and Headquarters Company (HHC), the PP halfway between At the BSB, the PP no more than 50 ft away from

Use the branch cables and two or three outlet boxes in the M46 to run a line of outlets for items like the CP of the Future (CPOF), laptops, cell phone chargers, etc.

Use extension cables to provide a single power drop for items such as Battle Command and Control System (BCCS) server and Joint Network Node (JNN) stack.

Provide a single power drop for the coffee pot to share with items that draw a lot of power, but are used infrequently, such as printers, plotters, or shredders.

Again, when connecting the M46 cables to the M40, use groups of three connectors. This helps keep the total load balanced on the generator, and prevents overloading any one phase. When in doubt, put the larger load on L3.

3.3.4.2 Maneuver BNs, BDE TAC

The BDE TAC and Maneuver BN Tactical Operations Centers (TOCs) each use one PP, MJQ-48, as the primary power source. Place the M40 near where the tents come together. Place the as close to the M40 and CPPs as possible, but no more than 50 ft from the CPPs.

Park the PP no more than 50 ft from the

Use the branch cables and two or three outlet boxes in the M46 to run a line of outlets for items like the CPOF, laptops, cell phone chargers, etc. Use the extension cables to provide a single power drop for items such as the BCCS server.

Provide a single power drop for the coffee pot to share with items that draw a lot of power, but are used infrequently, such as printers, plotters, or shredders. When connecting the M46 cables to the M40, use groups of three connectors.

This keeps the load balanced on the generator and prevents overloading any one phase. Put the larger load on L3.
