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.
