The mounting location must be flat and provide proper clearance, rigidity and strength to support the
enclosure and all contained devices.
WARNING
Securely fasten the enclosure to the mounting location, using 3/8-inch diameter
steel mounting bolts and washers, or washer head bolts.
WARNING
Do not disconnect equipment while energized.
Insure proper grounding to protective earthing.
WARNING
The front cover is not hinged to the rear enclosure. When the cover bolts are
removed, the cover must be adequately supported.
ATTENTION
Installation should be performed by qualified personnel and only in
accordance with the National Electrical Code or applicable local codes.
Inspect and clean the machined flange flame 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.
When installing any GAI-Tronics telephone equipment, please adhere to the following guidelines to
ensure the safety of all personnel:
• Electrostatic Discharge (ESD) Protection: Your telephone has an earth ground terminal provision.
Ensure that it is connected to ground in accordance with all local safety regulations and the National
Electrical Code (NEC). Grounding must be ensured for safe and stable communications. Do not use
long and coiled ground wires. Please note proper grounding does not eliminate the need for lightning
protection for the telephone or the telephone system.
• NEVER install telephone during a lightning storm.
• Install a UL Listed lightning arrestor on any phone installed where the phone or phone cable is at
risk of being exposed to lightning strikes. The lightning arrestor must be installed as close to the
telephone as possible in a non-hazardous environment to maximize the protection. The lightning
arrestor must not be installed within the telephone enclosure.
• NEVER touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
• USE CAUTION when installing or modifying telephone lines.
