2.7 UPS connection without a FlexPDU or HotSwap MBP module

   

 The 

HotSwap MBP module has a rotary 

switch (53) with two positions:
Normal - the load is supplied by the UPS,
Bypass - the load is supplied directly by the 
AC-power source.

   

  

    

1 - Evolution S 1250 / S 1750 / 2000: 
connect the UPS input socket (10) to the AC-
power source using the cable of the protected 
equipment.
Evolution S 2500 / S 3000: connect the 
supplied cable (31) (250 V - 16 A) to the 
socket (10), then to the AC-power source.
2 - Connect the loads to the UPS using the 
cables (32).
It is preferable to connect the priority loads to 
the four outlets marked (9) and the non-
priority loads to the four outlets marked (8) 
that can be programmed in pairs (1 and 2).
For the Evolution S 2500 / S 3000 models, 
connect any high-power devices to the 16 A 
outlet (7).

  

To program shutdown of outlets (8) during 
operation on battery power and thus optimise 
the available backup time, the MGE UPS 
SYSTEMS communication software is 
required.

3 - Fit the connection securing system (35) 
that prevents the plugs from being pulled out 
accidentally.

  

Note. The UPS charges the battery as soon as it is connected to the AC-power source, even if button (24) is not pressed.
Once the UPS is connected to the AC-power source, eight hours of charging are required before the battery can 
supply the rated backup time.
