Before Switch Operator Installation
Pre-Installation
Inspection and Setup
Before installing the 6801M Switch Operator, carry out the following steps. This is
best done in the shop before leaving for the installation site. Even if these steps are not
performed before installing the switch operator on the pole, S&C recommends doing so
before mechanically coupling it to the switch for operation.
NOTICE
Store the 6801M Switch Operator indoors or with 120-Vac power on when not
in service. The switch operator includes a drive-train assembly that can hold its
temperature for an extended period of time.
Under conditions of varying temperatures, this can promote buildup of moisture in
the enclosure caused by condensation.
Failure to store the product properly can void the warranty and promote conditions
leading to mechanical or electrical component failure.
The 6801M Switch Operator comes with the U-channel already installed. To stand
it up vertically, place it either on a very strong workbench or on two 4-inch (102-mm)
×
8-inch (203-mm)
×
24-inch (610-mm) wood blocks, and be careful not to damage the
components on the bottom of the enclosure.
NOTICE
The 6801M Switch Operator, with batteries, weighs approximately 260 pounds (118
kg). Use a lifting device (forklift, hoist, line truck, etc.) or get assistance from others
before attempting to lift the switch operator. A single point lift bracket is provided
on the rotating operator, and a lifting hole is provided in the reciprocating operator
mounting channel.
STEP 1.
Inspect the switch operator for visible damage. Make sure there is no obvious
damage to the switch operator enclosure or any internal components. Also
examine the inside of the enclosure for excessive moisture.
STEP 2.
Connect ac power to the switch operator.
Although this is not required for the
pre-installation inspection, it is required if you are updating the switch operator
software. S&C also recommends charging the batteries before attempting to
put the switch operator into service. Refer to Label G-6226 attached to the
enclosure door handle.
WARNING
The 6801M Switch Operator is capable of generating tremendous torque and
speed. Make sure the 24-volt dc circuit breaker is OFF before putting your hands
or other body parts near the actuator shaft. There is risk of SERIOUS injury if these
precautions are not observed.
NOTICE
Operating a switch with a 6801M Automatic Switch Operator may result in a
reduction of its fault-closing rating.
The fault-closing ratings for S&C switches applied with a 6801M Automatic Switch
Operators can be found in the following publications:
• S&C Omni-Rupter® Switches (see S&C Specification Bulletin 765-31)
• S&C Alduti-Rupter® Switches (see S&C Specification Bulletin 771-31)
For switches that are not made by S&C, contact the switch manufacturer to
determine whether there is an impact on their electrical ratings.
