5.3 Maintenance on a UPS Equipped With the HotSwap MBP Module
The HotSwap MBP module makes possible
to service or even replace the UPS without
affecting the connected loads (HotSwap
function).
Maintenance:
1. Set switch (53) to the Bypass position.
The red LED (52) on the HotSwap MBP
module goes ON, indicating that the load
is supplied directly with AC power.
2. Stop the UPS by pressing the ON/OFF
button (27) on the UPS control panel. LED
(51) “UPS ON - OK to switch” goes OFF,
the UPS can now be disconnected and
replaced.
Return to normal operation:
1. Check that the UPS is correctly connected
to the HotSwap MBP module.
2. Start the UPS by pressing the ON/OFF
button (27) on the UPS control panel.
LED (51) “UPS ON - OK to switch” on
the HotSwap MBP module goes ON
(otherwise, there is a connection error
between the HotSwap MBP module and
the UPS).
3. Set switch (53) to the Normal position. The
red LED (52) on the HotSwap MBP module
goes OFF.
