CHAPTER 11: MAINTENANCE
The relay, being modular in design, allows for the withdrawal and insertion of modules. Replace modules only with like
modules in their original factory configured slots.
To replace a module:
1. Open the enhanced faceplate to the left once the thumb screw has been removed. This allows for easy access of the
modules for withdrawal. The new wide-angle hinge assembly in the enhanced front panel opens completely and
allows easy access to all modules in the G60.
Figure 11-10: Modules inside relay with front cover open (enhanced faceplate)
The standard faceplate can be opened to the left once the black plastic sliding latch on the right side has been pushed
up, as shown below.
2. With power to the unit off, disconnect individually the connections from the module before removing the module from
the chassis.
3. To properly remove a module, pull simultaneously the ejector/inserter clips, located at the top and bottom of the
module. Record the original location of the module to ensure that the same or replacement module is inserted into the
correct slot. While modules with current input provide automatic shorting of external CT circuits, for CT/VT modules it
is recommended to short/isolate external circuits accordingly for maximum safety.
4. 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 is fully inserted.
