ESCRIPTION
Low Bypass Point
-30% of output 
voltage setting 
-15%, -20%, -25%, -30%
Minimum voltage that the UPS 
will pass to connected 
equipment during internal 
bypass operation.

Number of Connected 
Internal Battery Packs, 
(two modules per pack) 
Defines the number of 
connected battery packs for 
proper run time prediction. 
Connecting the EPO (Emergency Power Off) Option
The output power can be disabled in an emergency by closing a switch connected to the EPO.
Adhere to National and local electrical codes when wiring the EPO.
Rockwell Automation recommends Allen-Bradley Catalog Number 800F Emergency Stop Operator 
as the interface to the EPO to connector. 
The EPO switch is internally powered by the UPS for use with non-powered switch circuit breakers.
The EPO circuit is considered a Class 2 circuit, (UL, CSA standards) and a SELV circuit (IEC 
standard). 
Both Class 2 and SELV circuits must be isolated from all primary circuitry. Do not connect any 
circuit to the EPO terminal block unless it can be confirmed that the circuit is Class 2 or SELV. 
If circuit standard cannot be confirmed, use a contact closure switch.
