How to extract a ups-module in single module systems
WARNING!
THE WEIGHT OF A UPS MODULE CAN REACH 22KG, THEREFORE IT CAN
BE LIFTED BY 1 PERSON. WE RECOMMEND TWO PERSONS FOR
CARRYING THE MODULE.
POTENTIAL DANGERS:
THE UPS MODULE, DUE TO ITS WEIGHT, CAN CAUSE SERIOUS INJURY
OR DAMAGE SHOULD IT BE REMOVED INAPPROPRIATELY AND FALL.
NOTE:
WE RECOMMEND THAT THE MODULES ARE HANDLED BY TWO
PERSONS.
SUITABLE LIFTING TOOLS AND SAFETY EQUIPMENT SUCH AS
SAFEGUARD PLATFORMS TO HANDLE THE EVENTUALITY OF A MODULE
BEING DROPPED SHOULD BE PLANNED
If your
DPA UPScale
TM
consists of only one single UPS-module then perform following steps to
extract the module:
1.
Reset the alarm on the faulty module. The audible noise will stop. If the alarm condition
persists (the LED indicator ALARM will remain red) it means that there is a fault in the UPS
module.
2.
If the load is supplied by the mains in bypass-mode (eco-mode) the maintenance bypass (IA1)
may be closed by turning it to position “ON”.
NOTE: If the load is on inverter, then before closing the maintenance bypass IA1, transfer load
to bypass by means of the command “LOAD TO BYPASS” in submenu COMMANDS. On
LCD: “LOAD NOT PROTECTED” will appear.
3.
Close maintenance bypass switch IA1 (position ON)
On LCD: “MANUAL BYP IS CLOSED” will appear and the LED-indicator will indicate as shown
below:
