14 S&C Instruction Sheet 515-600
Installation
Complete the following steps to install the Alduti-Rupter Switches, switch operators, and
Micro-AT Source Transfer Control:
STEP 1.
Install the S&C Alduti-Rupter Switches and Type AS-1A or Type AS-10 Switch
Operators in accordance with the S&C instruction sheets and erection
drawings furnished with those devices. Also install the voltage transformers
and, if the
Overcurrent
Lockout
feature has been specified, the current
sensors in accordance with the instructions pro vided by the suppliers of those
devices.
STEP 2.
If the source-transfer control enclosure is to be pole-mounted by means
of the optional pole-mounting bracket (catalog number suffix “-P1”),
perform the following
:
(a) Drill two
11/16
-inch (17-mm) diameter holes 9
3/8
inches (238 mm) apart in the
center of the utility pole at the desired height for mounting the enclosure.
(b) Insert two
5/8
-inch diameter through-bolts (not furnished) in the holes just
drilled. Secure these bolts loosely with the necessary washers and nuts in
such a manner the heads of the bolts project suffi ciently (approximately 3
inches (76 mm) from the face of the pole) to engage the pole mounting
bracket.
(c) Attach two eyebolts (not furnished) to the holes pro vided at the top of the
enclosure mounting frame. See Figure 4 on page 15. Securely tighten the
eyebolts. Attach two suitable lifting slings to the eyebolts and slowly raise
the slings so they become taut. Carefully raise the enclosure to its mounting
level and guide it so the through-bolts projecting from the utility pole slip
into the two keyholes in the pole mounting bracket. Lower the enclosure
slightly so it bears on the through-bolts. Fully tighten the through-bolts,
making sure the washer for each bolt is between the bolt head and the pole
mounting bracket. Pro ceed to Step 3.
If the source-transfer control enclosure is to be steel-structure-mounted
:
Attach two eyebolts (not furnished) to the holes provided at the top of the enclo-
sure mounting frame. See Figure 4 on page 15. Securely tighten the eyebolts.
Attach two suitable lifting slings to the eyebolts and slowly raise the slings
so they become taut. Carefully raise the enclosure to its mounting level and
securely bolt it in place.
STEP 3.
Ground the enclosure by solidly connecting one number 6 AWG wire (or wires
of equivalent cross-sectional area) to the ground lug on the back of the enclosure.
See Figure 4 on page 15.
NOTICE
Failure to use proper-size ground wire may result in damage to the source-transfer
control .
