Model 670-001 Explosion-proof Speaker Station

Conduit Installation

Refer to Pub. 42004-185 or 42004-237 (Canada), which is shipped with this unit. These publications

detail how to maintain the explosion-proof integrity of the station.

NOTE

External conduits in areas with Class I, Group C and D areas must have gas seals

not more than 18 inches (457 mm) from the station enclosure. External conduits in Class II and

Class III areas must have seals if the conduit system is not dust-tight.

Wiring

After the station has been mounted, use a 7/16-inch wrench to open the front panel of the station to access

the Termination PCBA. Refer to Pub. 42004-185 or 42004-237 (Canada) for wiring details.

Feed the wiring through the conduit and into the enclosure. Follow the wire colors carefully—these

colors correspond to GAI-Tronics 60029 or 60038 Series cable. The wires must be spade-lugged and

connected carefully and completely to the terminal block. An improper termination may result in

diminished station performance.

Before closing the station, plug the power interconnect cable from the front of the enclosure into the

connector on the power supply card in the rear enclosure.

NOTE

All the bolts must be installed to maintain the integrity of the explosion-proof

construction.
