WARNING
Do not
mount the enclosure with hinges on the top or bottom side.
Securely fasten the enclosure to the mounting location, using 1/2-inch diameter steel mounting bolts and
washers, or washer head bolts.
WARNING
Do not disconnect equipment while energized.
Insure proper grounding to protective earthing.
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 an add-on station, consult the appropriate system layout diagrams. These figures, when
used in conjunction with the station installation information and cable layout guide, should provide all the
information necessary to install additional Page/Party
<
stations.
Enclosure Placement
All GAI-Tronics Page/Party
®
units are wired in parallel. Good system layout design minimizes the cable
required for each installation. GAI-Tronics multi-conductor cable, designed especially for this application,
is recommended. For the number, size, and color-coding of conductors refer to the appropriate system
connection diagrams.
System layout and power cable length are very important when installing Page/Party
<
equipment.
Although it varies for different systems, the general guideline is that the total power cable length should not
exceed one mile (5280 feet) for 120 V ac systems. The total cable length is the most important
consideration while cable length between the stations is generally not a factor.
