Installation
Opening the Station
WARNING
Before performing any of the following settings and adjustments, remove all
power from the station.
WARNING
To reduce the risk of hazardous atmospheres, disconnect the equipment
from the supply circuit before making any adjustments to the amplifier’s handset level.
Remove all cover bolts from the enclosure. Swing the front door open to access the internal PCBAs.
Field Wiring
The RTU PCBA provides terminal blocks for field wiring. Attach spade lugs to the wires before
attachment to the terminal blocks for the most secure connection.
OUTPUT 1A and OUTPUT 1B are activated by either the VLC or SmartSeries PCBA. OUTPUT 1B is
fused on the normally open (N. O.) contact with a T1.6 amp fuse.
Attaching the Front Panel
After all connections have been completed, inspect and clean the machined flange joint surfaces of both
the cover and box. Surfaces must be smooth, free of nicks, scratches, dirt or any foreign particle build-up
that would prevent a proper seal. Surfaces must seat fully against each other to provide a proper
explosion-proof joint. Clean surfaces by wiping with a clean lint-free cloth.
Apply a light coat of Killark “LUBG” lubricant to flange surfaces and close the cover. Install and tighten
all cover bolts to 30 ft.-lbs. Make certain no cover bolts are omitted. Use only those bolts supplied with
the enclosure.
It may become necessary to re-terminate some or all of the enclosures in a system. If so, strip the wires
back to clean copper and connect only one wire to each connector to allow for easier future
troubleshooting.
