Verify branch circuit breaker rating and wiring dimensions with the following table for hardwired input
UPS models.
INPUT/OUTPUT CONFIGURATION
Hardwire the input/output terminals as shown in the following diagram.
Input and Output circuit breakers must be “OFF” during the installation process.
An additional two pole disconnect device is necessary during the installation process.
Disconnected EPO will immediately shut down the logic circuit output of the UPS. Wiring the EPO port is
optional.
Local safety rules may require a separate, external EPO to turn off output circuit breakers. Refer to local
wiring rules, the EPO should use approved components.
OL6KRT Electrical Connection
Connect the NEMA L6-30P input power cord on the UPS to a properly wired NEMA L6-30R outlet. See the
Extended Battery Module Installation section for instruction on connecting the battery module to the UPS.
