ELECTRICAL CONNECTION INFORMATION

WARNING: High voltage may be present at receptacles and load studs while engine is
operating – DANGER of electrical shock is present. Use extreme care.
LOAD RECEPTACLES

2. Load wires may be brought into receptacle compartment through access door at control station.
HARD WIRE LOAD TERMINAL BLOCK
1. Voltage available at load block is outlined in chart below.
2. Cables must be brought into load block compartment through access hole in base of trailer.
3. Opening load block door will cause load disconnect to trip.
4. Do not start engine with load turned “on”. Allow engine to come up to speed and warm up (1).
5. If left unattended, lock all doors to prevent tampering or injury.
