67
8.3 Operating Instruction
Starting and stopping the ‘1+N’ system is the same as a single module, however the
module’s response depends on whether it is configured on the menu of the Operator
Control Panel.
8.3.1 System Start-up and shutdown procedures (Separate Batteries)
WARNING
If differential circuit breakers are used on UPS unit inputs, use a
common device only on the system’s bypass mains. At the instant of
electrical connection, the current may not be split instantaneously and
this may cause the residual current circuit-breakers to trip separately.
These operations must be performed one at a time, progressing to the next step only
after having completed the previous step on both UPS modules.
8.3.1.1 System Start-up
This procedure should be followed when tuning on the UPS from a fully powered down
condition – i.e. where the load is not being initially supplied at all. It is assumed that
the installation is complete, the system has been commissioned by authorized
personnel and the external power isolators are closed.
1.Open the UPS door(s) to gain access to the main
power switches.
WARNING
The following action will apply power to the load
equipment, ensure it is safe to do.
2. Close the Bypass power switch Q2
The Module Mimic LED’s will indicate Bypass
supply healthy (1-steady green) and the Load on
bypass (6 – flashing amber).
The display screen will show the following:
Initializing Window:
After first connecting power to the UPS and closing
the Q2 isolator, this message will appear on the
LCD screen. It persists for about five seconds
while the control firmware is loaded. It is followed
by a screen showing various messages with the
time and date on the bottom line.
Note: If input power is present but the display remains
blank, then the Micro controller is not working, pleas
contact your dealer for advice.
