WARNING

Do not mount the enclosu re with hinges on the top or bottom side.

Securely fasten the enclosure to the mounting location, using 1/ 2-inch dia meter steel mount ing bolts and
washers, or washer head bolts.

WARNING

Do not disconnect equipment while energized.

Insure proper grounding to protective earthing.

Inspect and c lean the machined flange fla me joint sur f aces of both the cover and b ox. Surfaces must be
smooth, f ree of nicks, scrat c hes , dirt or any foreign p article build-up that wou ld prevent a pr oper seal.
Surfa c es must seat fully aga inst ea c h other to provide a prop er explos ion- proof joint. C l ean surfaces by
wiping with a clean lint-free cloth.

Apply a light coat of Killa rk “LUBG” lub rica nt to flange surfac es and close t he cover. Ins tall and tight en
all cover bolts to 30 f t.-lb s. M ake cert ain no cover bolts are omitt ed. Use only thos e b olts supplied with
the enclos ure.

When installing an add-on st ation, consu lt the appr opriate sys tem layout diagrams. These figu res, when
used in conju nction with t he s tat ion insta llation information and ca b l e layout gu ide, should p rovide all t he
information necessary t o insta ll additional Pa ge/ Party< stat ions.

Enclos ure Placement

All GAI-Tronics Pa ge/ Party® units are wired in parallel. G ood system layout design minimizes the cable
required for ea ch insta llation. GAI-Tronics multi-condu c tor cable, des igned especially for this applic ation,
is rec ommended. For the numb er, s iz e, and color-coding of c onductors refer to the approp riate system
connection diagra ms .

System layout and power c able length are ver y important when inst alling Page/Party< equipment.
Although it vari es f or differ ent systems, the general guideline is t hat t he t otal p ower 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 sta tions is generally not a fa c tor.

The multi- party enclosures contain three ter mina l blocks, an int erior mount ing plat e, an a mp lif ier br idging
plate, a nd a connect or for the mating M odel 709-901 Amplifier. The amplifier bridging plate is hinged on
one side and attached on the opposite side with two #10-32 screws. For system cable installation, the
screws to t his pla te must be removed and the b ridging plate swu ng open 90º. Upon installation of the
wiring cable, the amplifier bridging plate can be rotated closed and reattached with the two #10-32 screws.
This plat e will then serve as a pr otection for the amplifier and t he switches fr om the s ystem cable when the
unit is complet ely closed. Refer to Figure 3.

The a lterna te page destinat ion selector switch is c onnected through an a dditional 8 - point terminal bloc k,
with wir ing directly to the fr ont door. The 8- point t erminal bloc k is located on the right side of the interna l
mounting plate. See Figure 3.

The part y line s elect or swit c h c an be disconnected from the a mplifier bridging pla te by means of the 12-p in
connector. Upon insta llation of system cable, after the amplif ier br idging plat e has been r eattached, p l ug
the 12- pin connector bac k into its receptacle.

OTE: The front door ca n be swung a ppr oximately 120º before the plug must be disconnected.
