equipment covered herein.
Electrical power is generated by a Lima 15 KW, A-C generator.The generator provides a constant 460 or 230 vac,
3 phase, 60 hertz electrical supply.
Before servicing unit, make sure the unit circuit breaker (CB-1 or CB-4) and the start-stop switch are in the
OFF position. Also disconnect power plug and cable.
Make sure the power plug(s) are clean and dry before connecting to any power receptacle.
High voltage (dielectric) testing must not be performed to the machine without first observing NEMA rules. The
insulation of this generator winding may be safely checked by using a megger. A high megger reading indicates
low insulation leakage.
The generator set circuit breaker must be in the ON position in order to supply power to the refrigeration unit.
