OPERATION
Forced Output
The forced output function should only be used by personnel who are knowledgeable regarding UPS battery string operation. Follow the instructions in the UPS battery owner’s manual.
The DC voltage selector switch must be set equal to the voltage of the UPS battery string. Incorrectly setting the voltage selector switch may cause damage or fire to the UPS battery string. The engine must be stopped whenever you change the DC voltage selector switch.
Forced output can only be initiated if the DC output does not initiate automatically when following the ‘‘STARTING THE ENGINE/DC OPERATION’’ procedure (see pages 23 － 25).
In addition, the forced output function is dependant on the UPS battery voltage string voltage. Forced output can only be initiated if the conditions shown in the following table are met.
Applicable conditions:
Output voltage depends on the DC voltage selector switch position. Forced output is allowed under the following conditions.
DC Voltage | UPS battery | Output indicator Overload indicator | |
Selector switch | Voltage | (Green) | (red) |
36 V | 2 － 27 V | OFF | FLASH |
48 V | 2 － 42 V | OFF | FLASH |
