Handling (cont.)
2. Select or adjust the rigging lengths to compensate for an unequal weight
distribution of the load and maintain the contactor in an upright position at
all times.
3. To reduce the tension of the rigging and the compressive load on the lifting
device, do not allow the angle between the lifting cables and vertical to
exceed 45 degrees.
4. Never lift a contactor above an area where personnel are located.
When a forklift is used to handle the equipment, the following considerations
should be taken:
1. Keep the contactor in an upright position.
2. Carefully balance the contactor on the forks.
3. Use a safety strap when handling to steady the contactor and avoid shifting
or tipping.
4. Avoid excessive speeds and sudden starts, stops and turns when handling the
contactor.
5. Never lift a contactor above an area where personnel are located.
Pre-energization Inspection
Before placing the contactor in service, inspect it carefully for possible damage
sustained in transit or during maintenance:
• Check that all interphase barriers are correctly installed.
• Check housing for any cracks or breaks due to impact.
• Push on the armature plate, rotating shaft to ensure mechanism is in good
working order.
• Inspect the contactor for dirt, stray loose hardware, tools or metal chips and,
if necessary, vacuum clean.
Storage
If it is necessary to store the contactor before it is put into service, be certain to
store it in a clean, dry, dust and condensation free area. Do not store the contac-
tor outdoors.
Storage temperature should be maintained between -20°C to 75°C (-4°F to
149°F). If storage temperature fluctuates or if humidity exceeds 85%, space heaters
should be used to prevent condensation. Preferably, the contactor should be
stored in a heated building having adequate air conditioning.
