Figure 4-20 External Signal Input Terminal Block (with default settings)

NOTE: For multiple battery cabinets, the UVR signals must be connected in parallel with UPS TN1-1 &-2.
For multiple battery cabinets, the Auxiliary Switches must be wired in series with UPS TN1-3 & -4.
* UVR is required for proper operation of system. If the UVR is not present or it is not
properly installed, the system warranty is voided. If you encounter this condition, stop and
do not continue with start-up. (See Figure 4-20 and Figure 5-4 for connection.)
CAUTION
The input logic can be reversed by setting the Active Level to "Neg" when selecting the input function.
This will be annunciated on the Setup screen for the inputs by an "R" next to the Input Port.
For Example:
"IN1 1" indicates the UPS will remote start when contact closes.
"IN1 R1" indicates the UPS will remote start when contact opens.
In all cases, a switch having a protective cover is recommended in order to reduce the
possibility of accidental operation.
