®
1772 Mini-PLC-2/15
The auxiliary power supply does not provide battery backup. For battery
backup, use a system power supply (cat. no. 1771-P1).
If You Are Mounting the Power Supply:
on the left side of the chassis
within 5 cable feet of the I/O chassis
If you mount the power supply on the left side-plate of the I/O chassis,
mount the I/O chassis first (if you have not already done so). See the
Universal I/O Chassis Installation Data (publication 1771-2.210) for
information on mounting the I/O chassis.
When mounted separately, the power supply can be mounted above or next
to the I/O chassis. It can not be mounted below since it is necessary to
allow convection cooling of both the power supply and the I/O chassis.
A minimum vertical distance of six inches should be maintained.
