The GE Terminal Board Relay Card 531X111PSHAPG2 supplies the 5 V dc, 15 V dc, and 24 V dc current used by the drive. It also features the pulse transformer for the motor field circuitry. The GE Terminal Board Relay Card 531X111PSHAPG2 is a replacement board and is designed to be installed only by qualified installers or servicers. Because the drive is a high-voltage device and also contains moving parts that can cause injury, only trained individuals should maintain and service the drive.
The process of installing the devices starts with inspecting the area around the drive for dangerous conditions. If there are any extension cords used in the area around the drive, only grounded extension cords can be used. Replace any two-wire cords with three-wire cords to reduce the chance of electric shock. The floor around the drive must be free of all moisture and also move any items that pose a trip hazard. This would include tools, cables, and other equipment.
Inspect all 3-phase power cabling in the area and consult with a individual familiar with the site to have full knowledge of the power supplied to the drive. Also, locate and inspect the shut off equipment used for the drive. Make sure the emergency shut off is in working order and can be reached easily in an emergency.
Never work on a drive without at least one other individual dedicated to being nearby and able to help in an emergency. This individual must be familiar with the site and emergency procedures.
