Receiving and Handling
Receiving
The contactors have been tested both mechanically and electrically before
leaving the factory. Immediately upon receiving the contactor, remove the
packing material and check the contactor for possible shipping damage. If
damage is found, do not discard any of the packaging material and, if possible,
note the damage on the “Bill of Lading” before accepting the shipment. Report
any damage immediately to the claims office of the common carrier. Provide a
description of the damage and as much identification as possible.
Preliminary Inspection
• Check for any cracks or breaks due to impact.
• Push on armature plate to ensure mechanisms are in good working order.
• Use a HiPot tester to ensure vacuum bottle integrity (refer to Vacuum
Bottle Integrity Test later in this Chapter).
Handling
The contactor weighs approximately 48 lb (21.8 kg) and it is possible for one (1)
person to safely handle the contactor for a short time. When transporting the
contactor over longer distances or sustained lifting, a fork lift should be
considered.
When a forklift is used to handle the equipment, the following precautions
should be taken:
• Keep the contactor in an upright position.
• Carefully balance the contactor on the forks.
• Use a safety strap to steady the contactor and avoid shifting or tipping.
• Avoid excessive speeds and sudden starts, stops and turns.
• 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 maintenance:
• Check housing for any cracks or breaks due to impact.
• Push on the armature plate and rotating shaft to ensure mechanism is in
good working order.
• Inspect the contactor for dirt, stray or loose hardware, tools or metal chips.
Vacuum clean the contactor if necessary.
