Power Distribution Module power output connectors are marked LAB A POWER
SOURCE for Mod Lab A and LAB B POWER SOURCE for Mod Lab B. Failure to
connect cables properly will restrict protective features designed into Power Distribution
(19) Remove Power Distribution Module (5) power cable connectors protective cap and firmly connect
laboratory power cables (4), male end, to Power Distribution Module proper female connectors.
Do not connect Power Distribution Module main power cable to Generator set until
Power Distribution Module is properly grounded. Failure to comply with this warning
could result in serious injury or death.
(20) Select an area as close as possible to Power Distribution Module (5) power inlet for grounding Power
(21) Repeat steps 3 through 11 to ground Power Distribution Module (5).
(22) Attach grounding cable to Power Distribution Module (5) GND grounding lug.
(23) Return driver/puller (5, figure 2-15) and driver/puller rod (3) to Mod Lab A (1, figure 2-14) roadside and
Mod Lab B (2) curbside storage boxes.
(24) Firmly connect female end of main power cable (6) to Power Distribution Module (5) power input male
connector, GEN SET POWER SOURCE.
(25) Route main power cable (6) to Generator Set (7).
Ensure main power cable is properly connected to generator set to prevent damage to
Mod Lab electrical system.
(26) Attach main power cable (6) to generator set (7) as follows: black wire (phase A) to L1; red wire (phase B)
to L2; blue wire (phase C) to L3; white wire (Neutral) to L4; green wire (ground) to GND.
Mod Lab A and Mod Lab B Electrical Startup and Purge Cycle. Perform the following procedures to apply
power to Labs.
Do not attempt to enter Mod Labs during start up until automatic purge cycle (5 minutes)
is completed. Dangerous combustible gases or vapors may be present which could ignite
and cause death or serious injury.
Unlatch and open two PURGE INTAKE and two PURGE EXHAUST doors on each Mod Lab.
Unlatch and open FUME HOOD AND GUM BATH VENT door on each Mod Lab.
Roll up and secure four Environmental Control Unit (ECU) canvas covers on each Mod Lab.
When power is applied to Laboratory an air purge cycle is automatically started utilizing
blowers in ECUs to pressurize Laboratory and expel any accumulation of gases. During
purge cycle all normal electrical circuits within Laboratory are disabled.
