Connect AC inputs
Connect 120/208/220VAC 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.
