BYPASS MODE
The UPS will automatically go to BYPASS mode in the event it is overloaded or suffers an
internal failure. When in bypass, the UPS will transfer the connected loads directly to utility
power. When in bypass mode, BATTERY MODE will not be available. However, the utility
power continues to be passively filtered by the UPS. The UPS will sound an audible alarm and
switch to BYPASS MODE automatically when:
•
The UPS has an overtemperature condition.
•
The UPS has an overload condition of 101 to 110% over 120 seconds.
•
The UPS has an overload condition of 111 to 150% over 20 seconds.
•
The UPS has an overload condition of over 150%.
•
The UPS detects a fault in the battery or UPS electronics.
The display shows the UPS in BYPASS MODE. The solid line is
connected from the Input to Load. Another solid line is connected
from the Input to Battery in charging. The Fan is in low speed;
Line and Charger icons are illuminated.
GREEN MODE
When Green Mode is turned on, the XG unit is automatically switched to “GREEN MODE”,
once the connected load drops to less than 3% of the UPS rated output. The load will operate
directly from utility power, similar to BYPASS MODE. The display indicates the UPS is in
BYPASS MODE, with a flash “GREEN MODE BULB”. If the load is increased to over 3% of the
UPS output rating, the UPS will switch back to NORMAL ON-LINE operation. All XG models
are shipped from the factory with GREEN MODE turned off. To enable “GREEN MODE”, refer
to the section on UPS “CONFIGURATION”. See the green mode configuration section for
further details and cautions.
TURNING THE UPS ON
Once installation is complete, the UPS can be powered up. With utility power present, turn on
the UPS INPUT BREAKER. The UPS will enter Auto-Start State; all of the indicators on the
display are illuminated. Ten seconds later, the unit goes to ON-LINE operation.
How to DC Start the UPS
To turn on the UPS without utility power available, press the “BYPASS” button. The UPS will
start on battery and supply power to the connected loads until the batteries are depleted.
Recharge the batteries immediately after a full battery discharge.
