Installing the Communication and Control
Unit
Before installing the communication and control unit, install
the S&C Scada-Mate Switch in accordance with Instruction
Sheet 768-500, shipped with the switch.
STEP 1. Drill two /-inch diameter holes 9⅜inches apart
in the center of the utility pole and at the desired
height for mounting the communication 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 communication 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 configuration.
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”).

included wiring diagrams for status inputs.
Testing the Remote Terminal Unit
STEP 14.After conguring the RTU (if furnished), testing
functionality of the communication and control
unit and the automated switch (if connected to the
communication and control unit via the control
cable) can be accomplished with a personal
computer and suitable user-supplied protocol test
software.
NOTICE
In some computers, the communication port signal
ground is internally connected to the chassis ground
to reduce electromagnetic interference (EMI). If such
a computer is used to test a communication device-
equipped communication and control unit, a ground
loop is created that will short-circuit one of the battery
packs.
To avoid short-circuiting the battery pack in the
event your computer has this internal connection,
temporarily disconnect the power connector of the
communication device. After the communication
and control unit has been tested, reconnect the power
connector to the communication device.
Test the remote terminal unit in accordance with
the manufacturer’s standards.

Emergency Manual Operation
In the event of electrical power loss, a standard or extendible
hookstick is used to open and close the interrupters. When the
spring is fully discharged, pull on the operating mechanism
pull-ring with the hookstick seven to nine times to effect a
change of state. If the spring is partially charged, just a single
pull will change the interrupter position. Refer to Figure 21.
