Supplement
AC/DC Adapter
(AD) Plug
for DC Power Supply Connection
Note
Ignore this supplement if the unit is AC-powered.
Certain units are equipped with a wide-range
AC/DC power supply. These units are equipped
with a standard AC-type 3-prong power input
connector located on the unit rear panel. This
power input connector can be used for both AC
and DC voltage inputs.
For DC operation, a compatible straight or
90-degree AC/DC Adapter (AD) plug for attaching
to your DC power supply cable is supplied with
your RAD product (see Figure 1 and Figure 2).
Figure 1. Straight AD Plug
Connect the wires of your DC power supply cable
to the AD plug, according to the voltage polarity
and assembly instructions provided on page 2.
Figure 2. 90-Degree AD Plug
Caution
Prepare all connections to the AD plug before inserting it into the unit’s power
connector.

AC/DC Adapter (AD) Plug
³ To prepare the AD plug and connect it
to the DC power supply cable:
1. Loosen the cover screw on the bottom
of the AD plug to open it (see
Figure 3).
2. Run your DC power supply cable
through the removable cable guard
and through the open cable clamp.
3. Place each DC wire lead into the
appropriate AD plug wire terminal
according to the voltage polarity
mapping shown. Afterwards, tighten
the terminal screws closely.
4. Fit the cable guard in its slot and then
close the clamp over the cable.
Tighten the clamp screws to secure
the cable.
5. Reassemble the two halves of the AD
plug and tighten the cover screw.

6. Connect the assembled power supply
cable to the unit.
Note: You have to flip over the
non-90-degree AD plug type by
180 degrees to insert it into the unit.
After inserting it, verify that the blue
(negative) wire is connected to the
POWER and the brown (positive) wire is
connected to the RETURN.
• Reversing the wire voltage polarity will not cause damage to the unit, but the
internal protection fuse will not function.
Warning
• Always connect a ground wire to the AD plug’s chassis (frame) ground
terminal. Connecting the unit without a protective ground, or interrupting the
grounding (for example, by using an extension power cord without a
grounding conductor) can damage the unit or the equipment connected to it!
• The AD adapter is not intended for field wiring.
