Installation
Installing the Communication and Control
Unit
Before installing the communication and con trol unit, install
the S&C Scada-Mate Switch in accordance with Instruction
Sheet 768-500, shipped with the switch.
STEP 1.
Drill two
11/16
-inch diameter holes 9
⅜
inches apart
in the center of the utility pole and at the desired
height for mounting the communica tion and control
unit. The communication and control unit should
be mounted at least 10-feet (305 cm) above
ground level to minimize exposure to vandals. See
Figure 5.
The maximum permissible distance between
the lower through-bolt of the switch and the top
through-bolt of the com munication and control
unit, when using the standard 35-foot (1067-cm)
control cable, is 28 feet 4 inches (864 cm)
for
switches in the upright, vertical, and pole-top
mounting configurations, or 32 feet 6 inches
(991 cm) for switches in the tiered-outboard
mounting con figuration.
These dimensions should be increased by 10 feet
(305 cm) when the switch is supplied with optional
45-foot (1372 cm) length control cable (catalog
number suffixes “-C45” or “-G45”). The above
dimensions should be reduced by 10 feet (302 cm)
when the switch is supplied with an optional 25-foot
(762 cm) length control cable (catalog number
suffixes “-C25” or “-G25”).
Figure 5. To minimize exposure to vandals the communica tion
and control unit should be mounted at least 10 feet (305 cm)
above ground level.
