2 Power connection
Connect AC mains to the back-plane of each power module with a mains cord with an IEC 320 connector.
There are two AC inlets, one for each power supply module. If the power module is equipped with a
single power supply only, the AC inlet for that position is used (the left inlet if the power supply is
installed in the left position as seen from the rear, and the right inlet if the power supply is installed in the
right position). If the power module is equipped with redundant power supplies, both inlets are used.
There is an on/off switch located in the front of the power supply.
If a DC power supply is used (not yet available), connect the DC input to the DB9 male connectors J2
and/or J3 in figure 1. If the power module is equipped with a single power supply only, the DC inlet for
that position is used (J3, DC input 1, if the power supply is installed in the left position as seen from the
rear, and the right inlet (J2, DC input 2) if the power supply is installed in the right position). If the power
module is equipped with redundant power supplies, both inlets are used.
