Bypass switch
Bypass switches are crucial components with which the PowerRouter supports critical
load situations. (The PowerRouter acts as an UPS system)
The bypass switch allows you to switch off the PowerRouter for maintenance, without
cutting power to the load. When the switch is activated, the mains supply is
redirected away from the PowerRouter, and directly to the load. The PowerRouter can
then be serviced and any maintenance work can be carried out without disturbing
the load. Once the PowerRouter is ready to be switched back on, the bypass switch is
deactivated and the supply is redirected back to the PowerRouter; the load receives
the high quality PowerRouter supply again.
The Bypass switch is an optional component and should be obtained and installed
separately.
