Wiring

All power and control connections are made at the

terminal strip within the amplifier enclosure, EXCEPT

GROUNDING. Power grounding must be made at green

ground screw on the housing base. 16AWG wire is

recommended for power and control circuits.

NOTE: There are special wiring requirements for intrinsic safety.

Observe all local electrical codes and proper wiring

procedures.

Caution: This unit contains CMOS electronics which may be

damaged by static electricity. Do not touch any semi-

conductor devices unless you are properly grounded.

PROCEDURE:

1. Make sure the power source is turned off.

2. Unscrew and remove housing cover.

3. Pull power supply and control wires through conduit

ground connection.

4. Connect green ground wire to green ground screw located

in the base of the housing.

NOTE: If separate I.S. ground is required in this application, then I.S.

ground (conventionally, blue #12 wire) should be connected to

the barrier at this time. Refer to NEC and agency guidelines.

5. After grounding is complete, connect AC power leads

to the HOT and COM terminals as marked. Refer to

Figure 6.

NOTE: For DC supply voltage connect DC+ to HOT and DC– to COM.

6. Connect control circuit leads to relay terminals. Refer to

Figure 6. Make sure the load to be controlled is within the

relay's rated capacity.

7. Prevent moisture seepage into housing by installing an

approved seal-drain fitting in the conduit run leading to

the unit.

8. Select operating mode. (Refer to OPERATING MODE

SELECTION on page 5 for detailed information.) Make

sure that the fail-safe switches are in the correct position

on page 5.

Caution: In hazardous areas, do NOT power the unit until the conduit

is sealed and the enclosure cover is screwed down securely.

9. Installation is complete. Replace housing cover.
