Push the wire in far enough such that it reaches the back wall of the connector, about a half inch
inside.
Attaching the Ground Wire
4 Tighten the clamp by tightening the screw above the slot into which you inserted the wire lead. The
wire lead should be securely attached inside the connector. You should be able to pull on the wire and not
dislodge it.
Warning. For both 48V and -60V input voltages, the positive (+) wire of the sourcing equipment, such as
a battery or rectifier, must be connected to the positive (+) terminal of the OmniSwitch DC power supply
and the negative (-) wire of the sourcing equipment must be connected to the negative (-) terminal of the
OmniSwitch DC power supply. This rule always applies to both 48V, and -60V input voltages, regardless
of the polarity signs shown on the power supply specification labels such as: -48V, +48V, or -60V.
5 Repeat Steps 2 through 4 for the remaining positive and negative wire leads.
