1.
Turn off the power.
2.
Open the seal on the front panel by removing the sealing wire, if found.
3.
Loosen the knurled screws on the face of the unit and gently remove the face and
attached circuit board by grasping the handles on either side of the front panel and
pulling the unit straight forward.
Pulling the board out at an angle or otherwise stressing the board on extraction may
damage the unit. Once removed from the case, position the unit face down on a static
secured mat.
Do not touch terminals inside the case after removing the plug-in unit.
Live terminals can be inside the case.
The signal connectors are left open when the plug-in unit is detached. The
CT inputs are still connected to auxiliary current transformers in the
analog input module mounted in the case. Thus, CTs are not disconnected
or open-circuited. The VT connections are not affected either.
