By-pass Operation
CB1, SW1, SW2 and the Battery CB are in the on position and SW3 is in the off position. In this mode, the load is supplied by the
mains through the static switch. This mode of operation does not condition the incoming power. The by-pass further ensures the
supply to the load in the event of an overload condition, manual inverter shut off or the unlikely event that the inverter should fail.
The by-pass is automatically activated in order to ensure that there is no interruption in the load supply.
In By-pass operation, the On By-pass and Summary alarm LEDs on the front panel are illuminated. The UPS returns to online
operation automatically once the fault has been corrected. This will happen only if it is electronically switched and not if the
inverter is manually turned off.
