INSTALLATION INSTRUCTIONS

a) Remove the cover retaining screws. Install the back box of the control station securely to a flat surface with screws that fit the 0.24 diameter hole or slot without damaging them. If needed, washers are permitted.

The enclosures are molded with "TOP" on the inside of the cover and the back of the box. For convenience, the back of the box has mounting dimensions molded into the back surface.

• b) Install the conduit or cable to the box using fitting that are certified as suitable for the area classification and service environment.
• c) Connect conductors to the component terminals.

Note: Normally-Open Contact Block has a white terminal housing, and is labeled "NO". Normally-Closed Contact Block has a grey terminal housing, and is labeled "NC".

Follow all wire stripping and terminal torque instructions for each component as described on the contact blocks.

Grounding connections are available at the din rail and hub locknut.

• d) Perform a continuity check to ensure the circuit is wired properly for the intended use.
• e) Before replacing the cover, ensure all wires are neatly installed within the control station base and are well away from the lid base joint and gasket area.

Replace the enclosure cover making note of "TOP" molded inside the cover. Thread each cover screw half way into the threaded insert without completely tightening. Snug the screws down in a diagonal pattern but don't overtighten.

DO NOT OVERTIGHTEN OR USE AN IMPACT TOOL.

A consistent fit over the entire length of the cover joint should be verified at the time of installation.
