Emergency Power Off Switch Wiring Procedure

1.Remove EPO wiring access panel.

2.Determine the type of EPO switch to be used: A contact closure or 24V dc. If a 24V dc EPO switch will be used, remove the factory installed jumper.

4.Attach flexible conduit, or appropriate wire/strain relief to panel.

5.Pull the wire through the conduit. Leave enough wire extending from the conduit strain relief to reach terminal blocks.

6.Strip approximately 1/2” (13 mm) of insulation from both wires. Secure a wire terminal to each wire. Note: It is recommended that ring terminals (crimped) be used to ensure good electrical connection.

7.Connect wires as shown according to switch type.

8.Inspect wiring to ensure proper connections. Carefully fold wiring into the entry compartment and remount the access panel.
