Mounting
Mounting Direction
Use standard mounting only. Using any other mounting method
will prevent proper heat dissipation and may result in deterioration
or damage of internal elements.
Stopping Unit
When stopping a connected unit during maintenance, we
recommend first making sure that backup operation is not needed
before turning the battery holder switch and then the AC power line
OFF.
