2-7. ASSEMBLY AND PREPARATION FOR USE - continued.
Place driver/puller and driver/puller rod in storage box.
Slide grounding cable clamp over grounding rod.
Attach grounding cable to grounding rod with grounding clamp.
Attach grounding cable to grounding lug in power input panel. (Refer to Figure 2-17.)
Petroleum Laboratory Electrical Startup and Purge Cycle. The following procedure is used to apply power to
the Petroleum Iaboratory.
Do not attempt to enter the Petroleum Laboratory 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 the two PURGE INTAKE and the two PURGE EXHAUST doors.
Unlatch and open the gum bath/fume hood exhaust door.
Roll up and secure the four ECU canvas covers in the up position.
The main power input cable is stored in the roadside storage box.
Remove the main power input cable from the storage box.
Be sure that main power cable leads are properly connected to the
generator set to prevent damage to the generator set or laboratory
Attach main power cable leads to the generator set as follows: Black wire - phase A (L1); Blue wire -
phase B (L2); Red wire - phase C (L3); White wire - Neutral (N); Green wire - Ground (Gnd).
Remove protective cap from main power cable connector (Figure 2-17) at the power input panel.
Firmly connect the main power input cable to the cable connector.
When power is applied to the Petroleum Laboratory, an air purge cycle
utilizing the ECUs blowers to pressurize the laboratory and expel any
accumulation of gases is automatically initiated. The cycle will last for
approximately 5 minutes. During the purge cycle, all the normal
electrical circuits within the petroleum laboratory are disabled.
