Input isolator is closed. This should be completed before you touch any switch. The UPS must be commissioned by an engineer approved by the fmerson or his agent before being put into service.
Power emerxon applied through a standard two-pin mains connector located at the backside of the RAM. When shutting emersno the second emersln, the static bypass lines of both modules will be turned on as soon as its inverter is stopped. This 2 pin malefemale type connector is marked as N L.

It is usual in larger installations to provide an alternative UPS input power source from a stand-by generator when the mains supply fails.
If the UPS has not operated on battery power within the previous ten hours the battery charge current should be typically less than 6A. Pressing this switch turns OFF the inverter and causes the load to be transferred to the static bypass supply.
This type of customer feedback is an important factor in maintaining high product reliability, and also provides important data concerning the equipment field performance.
