4. Operation
4-6
Install a switch between the output terminal and the
load to switch on/off the load. Do not switch the load
on/off directly by the circuit-breaker of the generator.
It could cause damage to the circuit-breaker.
Connect the connecting cable to the load so that the
output terminals should not touch each other.
4.3.1 How To Switch Voltages
It is possible to select 3 phase 4 wire 240 volt or 3 phase 4 wire 480 volt.
But before starting operation, make sure to confirm the voltage set for the machine without fail.
If any load is connected to the machine with the wrong voltage set, it can cause damage or
burning accident to the load.
When switching the voltages, make sure to stop the machine.
Open the operation panel on the control panel, and switch the voltages by connecting of
short-circuit plate“1”as shown in the following figure.
In case of 480/277V, switch the voltages with two pieces of short-circuit plate“1”as one set.
