Details

The GE Power Excitation Board DS200RTBAG3AHC is an optional board that is installed in the drive cabinet and it features ten relays that are driven either directly from the pilot relays or remotely by the user.

The DS200RTBAG3AHC board has 52 terminal points. The terminal points are for I/O purposes. For example, one series of terminal points is for relay K20 form C contact. One terminal point is for the normally open position, one terminal point is for common, and one terminal point is for the normally closed position.

The board also has two stab connectors. The connectors are CPH and CPN and they provide pluggable circuit control power. CPH is the positive power connector and CPN is the negative power connector.  The pluggable circuits that provide power are the C1PL through C5PL and Y9PL through Y37PL pluggable circuits. For example, one connector provides the positive pluggable circuit control power. And another is for the negative pluggable circuit control power.

The DS200RTBAG3AHC board contains high energy and is a safety risk if it is touched while power is connected to the board.  It is also a risk to touch any other components in the drive. You must follow a procedure to disconnect all power from the drive and the board.

First, use the control panel to stop the motor and use the standard procedure to shutdown the drive in an orderly fashion. To disconnect all power from the drive locate the power supply that provides the 3-phase electrical current and pull out the fuses.
