Normal

 

The external bypass is used for changing over between 

¾ "NORMAL" operation (default switch position), 

i.e. secure load supply with UPS back-up. 

¾ "TEST" operation (service position), 

i.e. load supply directly from the mains, 
additional mains supply to the UPS for service purposes. 

¾ "BYPASS" operation (bypass position), 

i.e. load supply directly from the mains, 
additional complete isolation of the UPS 
(Attention! UPS output may still be live due to its internal 
voltage source!) 

If there is a mains failure during "TEST" and "BYPASS" 
operation then the supply to the connected loads will be 
interrupted. 

IMPORTANT:  UPS must be switched to “BYPASS” operation, 

if external bypass switch will be operated ! 
(refer to the UPS operating instructions) 

 

During subsequent installation in the rack, take care that the unit is 
located close to the UPS so as firstly to establish the causal 
connection between the two and secondly to facilitate connection 
and subsequent replacement of the UPS.
