SECTION 5: INSPECTION, MAINTENANCE,
AND INSTALLATION
WARNING
ALL WORK PERFORMED ON THIS STARTER SHOULD BE DONE WITH THE
MAIN DISCONNECT DEVICE OPEN AND LOCKED OUT. AS WITH ANY
STARTER OF THIS VOLTAGE, THERE IS DANGER OF ELECTROCUTION AND/
OR SEVERE BURNS. MAKE CERTAIN THAT POWER IS OFF. CHECK FOR
VOLTAGE WITH VOLTAGE SENSOR OR A METER OF THE APPROPRIATE
RANGE. MAKE CERTAIN THAT ALL TRANSFORMERS ARE ISOLATED
TO PREVENT FEEDBACK AND THE RESULTANT GENERATION OF HIGH
VOLTAGE.
The starter should be serviced on a regular basis. The time interval
between maintenance checks is variable and dependant on factors
such as environment, duty cycle, etc. Unless the experience of the
maintenance personnel suggests a different service interval, the
contactor should go through a checkout after each 50,000 operations
or annually, which ever occurs first.
5.1 GENERAL
The starter should be kept clean and free from dust and other
accumulated deposits. Dust can be removed from the starter by
wiping with a lint free cloth.
Inspect for loose joints that produce excess heat and discolor
conductors. Verify that insulation has not been damaged by high
temperatures. Do not over-torque bolts while verifying tightness.
Hardware is both Metric and US standard sizes. Refer to Table 5.3
for recommended torque values.
WARNING
BEFORE PLACING THE STARTER IN SERVICE, CAREFULLY FOLLOW THE
INSTALLATION PROCEDURE IN THIS MANUAL AND THE SAFE PRACTICES
SET FORTH IN SECTION 2. NOT FOLLOWING THE PROCEDURE MAY RESULT
IN INCORRECT STARTER OPERATION LEADING TO DEATH, BODILY INJURY,
AND PROPERTY DAMAGE.
When the starter is first commissioned into service and each time
the starter is returned to service, it should be carefully examined and
checked to make sure it is clean and operating correctly.
5.2 EXAMINATION FOR DAMAGE
Examine the starter for loose or obviously damaged parts. Never
attempt to install nor operate a damaged starter.
5.2.1 NAMEPLATE VERIFICATION
Compare the starter nameplate information with switchgear
drawings for compatibility. Starter and compartment code plates do
match power ratings, but do not match control voltages.
5.3 INITIAL INSPECTION AND OPERATION
Inspect the starter for any damage that occurred during shipment,
storage, and installation.
Set the dip switches in the coil control board for the proper control
voltage and dropout time (Figures 4.1 and 4.2 and Tables 5.1 and
5.2). When control information is supplied, dip switches will be
factory set.
Sequence the control circuit, including closing the starter with the
main power circuits de-energized and locked out.
Verify that the starter will be connected to an incoming power
supply and outgoing load with characteristics agreeing with the
starter rating and coil burden requirements.
