The external bypass is used for changing over between
¾"NORMAL" operation (default switch position), i.e. secure load supply with UPS
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)
3. Installation (mechanical)
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.
