Genset Frequency Configuration—60Hz and 50Hz Modes
Shock/Electrocution Hazard! Read and understand the instructions and warnings in the Operation and Maintenance
Manual. Failure to follow the instructions or heed the warnings could cause serious injury or death.
DO NOT OPEN the inner main panel door unless you are a qualified service technician, and are familiar with the dangers of
high voltage. The main electrical lines coming into the bottom of the main supply AC circuit breaker (CB1) from the genset
are LIVE, and HIGH VOLTAGE is present on the main incoming lines WHENEVER the genset is running, EVEN WHEN
THE MAIN CIRCUIT BREAKER (CB1) IS DE-ENERGIZED (O).
The genset can be configured to provide either 480/120-240VAC at a frequency of 60Hz, or 415/240VAC at a frequency of
50Hz.
Note: A different Single Phase Front-Mounted Equipment Receptacle Plate is required for 60Hz and 50Hz operation, and no
voltage will be present in the front-mounted equipment receptacles if the wrong plate is used. Refer to the section Single
Phase Front-Mounted Equipment Receptacles—Installation in the Maintenance Section of this manual for changing over
between the different receptacle plates.
Note: To avoid possible equipment damage, ensure that only equipment with the correct voltage and frequency ratings are
connected to the supply receptacles.
Follow the steps below to configure the unit for the desired AC electrical output.
1. Open the inner panel by turning the three securement latches clockwise approximately 1/2 turn.
2. The Genset frequency selector switch SS60/SS50 (1) is located on the inner panel, in the upper rear quadrant.
3. Refer to the 60Hz Mode or the 50Hz Mode below for the set-up procedure for the desired operation mode.
