Field Wiring Connections for the AC/DC Input Power Supplies
The two AC/DC input power supplies have six terminals for user connections. These connections
are described below.
AC Power Source Connections
The Hot, Neutral, and Ground wires from the
20 VAC power source or L
, L2, and
Ground wires from the 240 VAC power source connect to the system through the top three
terminals of the terminal strip on the front of the power supply.
DC Power Source Connections
Connect the
+
and
-
wires from the
25 VDC (nominal) power source to the top two
terminals on the terminal connector. These connections are not polarity-sensitive on an
AC/DC input power supply. (However, the DC Input-only type supplies, which are
discussed later in this chapter, are polarity sensitive.)
Input Overvoltage Protection Devices
This information applies to all Series 90-30 power supplies except IC693PWR322
and IC693PWR328.
The overvoltage protection devices for this power supply are
connected internally to pin 4 on the user terminal strip. This pin is normally connected to
frame ground (pin 3) with the supplied jumper strap which is installed at the factory. If
overvoltage protection is not required
or
is supplied upstream, this feature can be disabled
by removing the jumper strap from pins 3 and 4.
