Safety Precautions
DANGER
S&C Scada-Mate Switching Systems contain high voltage. Failure to observe the
precautions below will result in serious personal injury or death.
Some of these precautions may differ from your company’s operating procedures and
rules. Where a discrepancy exists, follow your company’s operating procedures and rules.
1. QUALIFIED PERSONS.Access to switches and
controls must be restricted only to qualified persons.
See “Qualified Persons” on page 2.
2. SAFETY PROCEDURES. Always follow safe operating
procedures and rules.
3. PERSONAL PROTECTIVE EQUIPMENT. Always use
suitable protective equipment, such as rubber gloves,
rubber mats, hard hats, safety glasses, arc-flash
clothing, and fall protection, in accordance with safe
operating procedures and rules.
4. SAFETY LABELS. Do not remove or obscure any of
the “DANGER,” “WARNING,” “CAUTION,” or “NOTICE”
labels and tags. Remove tags ONLY if instructed to do
so.
5. OPERATING MECHANISM AND BASE.The stored-
energy operating mechanism and switch base contain
fast-moving parts that can severely injure fingers. Do
not remove or disassemble the operating mechanism
or remove access panel on the switch base unless
directed to do so by S&C Electric Company.
6. ENERGIZED COMPONENTS.Always consider all
parts live until de-energized, tested, and grounded.
7. GROUNDING. Before energization and at all times
when energized, the switch base and control unit
enclosure must be connected to suitable earth ground
at the pole base in accordance with the S&C instruction
sheet furnished with this device.
The switch base ground must also be connected
to the system neutral. If the system neutral is not
present, proper precautions must be taken to ensure
the local earth ground cannot be severed or removed.
8. LOAD-INTERRUPTER SWITCH POSITION. Always
confirm the Open/Close position of load-interrupter
switches by visually observing the indicator.
Interrupters and terminal pads may be energized from
either terminal.
Interrupters and terminal pads may be energized with
the interrupters in any position.
9. MAINTAINING PROPER CLEARANCE.Always
maintain proper clearance fromenergizedcomponents.

Shipping and Handling
Inspection
Examine the shipment for external evidence of damage as
soon after receipt as possible and preferably before removal
from the carrier’s vehicle. Check the bill of lading to make
sure that all shipping skids, crates, and containers listed are
present.
If there is visible loss and/or damage:
STEP 1. Notify the delivering carrier immediately.
STEP 2. Ask for a carrier inspection.
STEP 3. Note condition of shipment on all copies of the
delivery receipt.
STEP 4. File a claim with the carrier.
If concealed damage is discovered:
STEP 1. Notify the delivering carrier within 15 days of
receipt of shipment.
STEP 2. Ask for a carrier inspection.
STEP 3. File a claim with the carrier.
Also, notify S&C Electric Company in all instances of loss
and/or damage.
Packing
The communication and control unit is packaged and crated
appropriately to avoid damage during shipment. A catalog
drawing and wiring diagram for the communication and
control unit is located in a water-resistant envelope in the
instruction manual holder inside the control unit enclosure.
Similarly, a catalog drawing and wiring diagram for the
selected S&C Scada-Mate Switch is located in a water-
resistant envelope attached to the switch. Study these
drawings carefully and check the parts list to verify all parts
are at hand.

the following:
1. Switch
2. Communication and control unit
• Optional remote terminal unit
• Optional communication device
• Stainless steel enclosure
• Miscellaneous parts and pieces
3. Control cable
4. Optional features not assembled to switch
5. Yellow card—sensor data for switch
6. Instruction manual
Storage
If the communication and control unit will not be placed
into service by the date marked on the control, the batteries
will require charging. See the “Charging the Battery Packs”
section on page 25.

Installation
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”).
Figure 5. To minimize exposure to vandals the communication
and control unit should be mounted at least 10 feet (305 cm)
above ground level.

Installation
STEP 2. Insert two /-inch diameter through-bolts (supplied
by others) in the holes drilled in Step 1. Secure these
bolts loosely with the necessary washers and nuts
so the heads of the bolts project sufciently
(approximately 3 inches (76 mm) from the face of
the pole) to engage the enclosure mounting frame.
For installation with a switch in the vertical
mounting conguration, mount the communiction
and control unit on the face of the pole opposite the
switch to allow space for the cable riser.
STEP 3. Attach an appropriate lifting sling and slowly raise
the sling so it becomes taut. Carefully raise the
control unit to the mounting height and guide it so
the through-bolts projecting from the utility pole
slip into the two keyholes in the enclosure mounting
frame. Lower the enclosure slightly so it bears on
the through-bolts. Fully tighten the bolts and make
sure the washer for each bolt is between the bolt
head and the mounting frame.
STEP 4. Ground the enclosure by solidly connecting one No.
6AWG wire (or wires of equivalent cross-sectional
area) to the ground lug on the back of the enclosure.
See Figure 6. Solidly connect the other end of the
enclosure ground wire to the switch ground wire(s).
Figure 6. The enclosure ground lug is on the pole side.
