QUICK START GUIDE
23" Single Voltage system Without adaptor bus bars
Step 3 - Connect AC inputs
Connect 120/208/240VAC at rear of each rectifier
shelf.
Danger: Turn OFF and lock-out tag-out the AC source
before making AC connections. When connecting to
AC mains, follow all local and national wiring rules.
Caution: When routing AC ensure cables do not
come in contact with sharp or rough surfaces that
may damage insulation and cause a short circuit.
Rectifiers numbers are labeled at each AC input.
AC terminal connections are labeled at each position (L1, L2/N, and Gnd).
AC Terminal Block is in the AC box on the rear of the rectifier shelf
Connect AC input cord to the detachable input terminal block in the wiring box – knock out for ¾" conduit or cord
grip. Strip and torque per the table. Pull on wire to verify secure connection.
AC Input
AC1 - Molex mini-fit SR
AC3 - IEC-320 C19
AC5 - Terminal Block
AC6 - Terminal Block 3-phase Delta
AC7 – Terminal Block 3-phase Wye

The rectifier will output 75A in 19" systems with AC5, AC6 or AC7 inputs and in 23" systems with AC5H inputs. All other inputs automatically de-rate the rectifier
to 50A output
