Station Wiring
While supporting the front cover, remove the twelve cover bolts on the enclosure flange. Pull the front
cover far enough away to expose the internal connections and disconnect any wiring between the front
cover and rear enclosure. Place the front cover aside.
Attach the cable glands to the holes on the bottom of the enclosure.
Cable glands must be certified to current ATEX and IECEx standards for type ‘d’ Flameproof protection
as well as ambient protection.
In rigid conduit systems, a sealing fitting must be installed in accordance with local codes.
Feed the low-voltage wiring on the left side hole and the power wiring through the right side hole. Refer
to Figure 2.
Attach the wires to the terminal blocks located on the PCBA within the enclosure. See Figure 4 and
charts for connection points and descriptions. Use one conductor (0.50 mm
2 to 4 mm 2 ) per screw
terminal. Apply torque to 0.6 N-m.
If using the 10438-101 Auxiliary Microphone Assembly, connect the assembly to the station at terminal
block TB4-1 (+) and TB4-2 (−), shield to TB4-5, if used. The maximum distance from the station is 50
feet using 1 mm
2 wire.
If using an auxiliary footswitch assembly (customer supplied), connect the assembly to the station at
terminal block TB4-8 (+) and TB4-9 (−), shield to TB4-5, if used. The maximum distance from the
station is 50 feet using 1 mm
2 wire.
In this operation, the auxiliary microphone replaces the speaker as the microphone, and the auxiliary
footswitch provides parallel functionality to the push-to-talk switch.
