1.3 Unpacking and Inspection
Unpack all items and save the packing materials in case you ever need to move the system. Inspect the contents of
the shipping carton as you unpack. If any of the following items are damaged or missing, contact your dealer
immediately.
! The UPS
! This user’s guide
! Two output power cord
! One input power cord
! One external battery wire (Long back-up time model only)
For the UPS with battery inside, a small plastic plate is inserted to the power switch to prevent it from being
accidentally switched on during shipment.
CAUTION- Do not remove the power switch security plate until the UPS has been properly inspected and
installed
1.4 The Front Panel
! (A) LINE: This green LED is on when the ac utility is normal, it is off when
in battery mode.
! (B) BYPASS: This yellow LED is on when the UPS is providing power
directly from the incoming ac utility through the bypass line.
! (C) INV: This green LED is on when the UPS power is from its inverter to
the load.
! (D) ALARM: This red LED is on when the UPS power is in a fault
condition. In the meantime, the alarm beeps continuously.
! (E) CAPACITY: This green LED bar indicates the load size in main mode
or the battery capacity in battery mode. In addition, it also indicates the
fault status when the ALARM red LED is on.
! (F) FULL LOAD: This yellow LED is on when the UPS is in full load
condition; please unplug the least critical equipment, such as a printer
etc.
! (G) OVERLOAD: This red LED is on when the UPS is in over load condition. Unplug some equipment immediately
until this LED is off. Otherwise the UPS will transfer to bypass mode after 20 seconds.
CAUTION- Ensure this LED is off within 20 seconds in battery mode. Otherwise the UPS will be turned off
because of no ac power in bypass.
! (H) MAIN SWITCH: Turn on the UPS by depressing this switch into “ | “ position and turn off the UPS by
depressing this switch into “
” position.
