OPERATING INSTRUCTIONS
Turn On
Once the AC supply has been applied to the unit, power will be applied to the load (bypass
mode) immediately when the 30 A input circuit breaker is initially closed. Turn the unit ON
(inverter mode) by pressing the ON button once.
Manual Bypass
To manually put the unit in Bypass mode, press the Standby button once. Pressing this
button once will cause the load to be transferred to bypass power. Pressing this button a sec-
ond time will result in loss of power to the output receptacles and connected loads.
Standby
To put the unit in Standby mode, press the Standby button while the unit is in bypass
mode.
!
CAUTION
Pressing the Standby/Manual Bypass button during normal
operation while the inverter is on will transfer the load to bypass
power, if the bypass voltage and frequency are within a safe
range.
The bypass power path does NOT protect the connected
equipment from disturbances on the utility supply.
!
CAUTION
Pressing the Standby/Manual Bypass button when the UPS is in bypass
mode will shut off power to the output receptacles and connected loads.
Turning the unit off leaves the UPS in standby mode. To fully isolate the
load from power, open the input circuit breaker.
