3.3 Replacing the Batteries
While the batteries are being replaced, the UPS cannot provide backup battery
power. This procedure should NOT be done when critical loads are running that
depend on this unit for backup power.
Procedure
1. For Model 1000, if the UPS is in Line,
Buck or Boost mode (See Figure 3.2.2)
go to the control submenu to switch it
into Inverter Bypass (See Section 3.4
also see the Control Panel Tutorial in this
section). If it isn’t in those modes, wait
until the line is qualied.
For Models 300 & 600, you can only
switch the operating mode to Inverter
Bypass using the Novus Micro Graphical
User Interface. See Section 4.6 for
details.
2. Turn off the battery circuit breaker.
3. Unplug the battery string.
4. Disconnect the battery cables from the
batteries.
5. Connect the battery cables to the new
batteries.
6. Plug the battery connector into the UPS.
7. Turn on the battery circuit breaker.
8. Switch the UPS out of Inverter Bypass.
