11.1 MODULES
To properly remove a module, the ejector/inserter clips, located at the top and bottom of each module, must be pulled
11
simultaneously. Before performing this action, control power must be removed from the relay. Record the original loca-
tion of the module to ensure that the same or replacement module is inserted into the correct slot. While modules with cur-
rent input provide automatic shorting of external CT circuits, for CT/VT modules it is recommended to short/isolate external
circuits accordingly for maximum safety.
To properly insert a module, ensure that the correct module type is inserted into the correct slot position. The ejector/
inserter clips located at the top and at the bottom of each module must be in the disengaged position as the module is
smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips simultaneously.
When the clips have locked into position, the module will be fully inserted.
CPU connections must be individually disconnected from the module before the module can be removed from the
chassis.
