4.8 Preliminary Checks

After the ATS enclosure is installed and power cables are con-
nected to the equipment, thoroughly inspect the unit to ensure
that no tools were left inside and that the cabinet is free of debris.
If necessary, use a vacuum cleaner to remove any and all con-
struction or installation debris from the equipment.
Read and understand all labels on the equipment. Review and
understand the wiring diagrams supplied with the equipment.
Note any optional accessories that may have been furnished with
this unit and review their operation.
Verify that the phase-to-phase line voltages of both the utility and
generator power sources are the same and that they match the
rated voltage as indicated on the ATS ratings label.
SEVERE EQUIPMENT DAMAGE CAN RESULT IF THE UNIT IS NOT
APPLIED AT PROPER VOLTAGE. DO NOT ENERGIZE THE EQUIP-
MENT IF THE SUPPLY VOLTAGES DO NOT MATCH EQUIPMENT
RATINGS LABEL.
4.9 Protection
For Catalog # EGS100L24R only
When protected by one of the following circuit breakers rated not
more than 150 amperes, this transfer switch is rated for use on a
circuit capable of delivering not more than 25,000 RMS symmetri-
cal amperes, 240 volts maximum, but not more than the interrupt-
ing capacity of the selected circuit breaker.

When protected by circuit breakers without adjustable short-time
response only or by fuses this transfer switch is rated for use on a
curcuit capable of delivering not more than 10,000 RMS symmet-
rical amperes at 240V AC.

SECTION 5: FUNCTIONAL TESTING
YOU ARE READY TO ENERGIZE THE EQUIPMENT. VOLTAGES
WITHIN THE ENCLOSURE ARE CAPABLE OF CAUSING SEVERE PER-
SONAL INJURY OR DEATH. USE EXTREME CAUTION TO AVOID
CONTACT WITH ENERGIZED EQUIPMENT.
5.1 Preliminary Checks
Step 1: Check all loads connected to the ATS to ensure that they
are ready to be energized.
5.2 Energize the Switch
Step 1: Close the upstream utility power source breaker or
switch to connect the ATS to the utility power source
voltage.
Step 2: Using a voltmeter, measure the line-to-line and the line-
to-neutral voltages across the utility line terminals to
ensure the utility voltage is correct.
Step 3: If the voltage is acceptable, the solenoid will engage and
the contactor will automatically switch to the UTILITY
position.
CONTACT WITH ENERGIZED COMPONENTS WILL CAUSE ELECTRI-
CAL SHOCK CAPABLE OF PRODUCING SEVERE PERSONAL INJURY
OR DEATH. USE EXTREME CAUTION TO AVOID CONTACT WITH
ENERGIZED COMPONENTS WHEN USING A METER FOR VOLTAGE
CHECKS.
Step 4: Position the generator control selector switch, located on
the standby generator, to the AUTOSTART position. (It
may also be labeled REMOTE START or AUTO.)

5.3 Operational Checks

Step 1: Open the upstream utility breaker originally closed in
Step 1 of Section 5.2.
THIS WILL SIMULATE AN INTERRUPTION OF THE UTILITY POWER
SOURCE.
Step 2: After a time delay (based on the generator settings), the
standby generator engine will start.
Step 3: Using a voltmeter, measure the line-to-line and line-to-
neutral voltages across the generator line terminals to
ensure that the generator emergency voltage is correct.
If necessary, make adjustments to the voltage regulator
on the generator according to the manufacturer's recom-
mendations to correct any voltage deviations. The ATS
will only respond to the correct voltage from the genera-
tor power source.
Step 4: Close the upstream generator power source breaker or
switch to connect the ATS to the generator power supply
source.
