ES8108-XT/ES8108F-XT IN CID2 ENVIRONMENTS
The ES8108-XT and ES8108F-XT are open-type and are to be installed in an
enclosure suitable for the environment and only accessible with a tool.
The ES8108-XT/ES8108F-XT is suitable for use in Class I, Division 2, Groups A,
B, C, and D or non-hazardous locations only.
WARNING - EXPLOSION HAZARD – Substitution of any components in the
ES8108-XT or ES8108F-XT may impair suitability for Class I, Division 2.

WIRING THE POWER INPUTS

The ES8108 provides redundant power, reverse polarity protection and
accepts a positive or negative power source. If using redundant power
supplies, they must be in the same mode.
Use this procedure to wire the power:
1. Insert the positive and negative wires into the + and - contacts on the
PW1 or PW2 on the terminal block connector.
2. Tighten the wire-clamp screws to prevent the wires from being loosened.
Note: Power should be disconnected from the power supply before connecting
it to the switch. Otherwise, your screwdriver blade can inadvertently short
your terminal connections to the grounded enclosure.
