2.1 Power Supply Connections
1. First prepare the AC adapter for the country where it will be used by selecting the plug.
The OP7200 Tool Kit presently includes Canada/Japan/U.S., Australia/N.Z., U.K., and
European style plugs. Snap in the top of the plug assembly into the slot at the top of the
AC adapter as shown in Figure 2, then press down on the spring-loaded clip below the
plug assembly to allow the plug assembly to click into place.
Connect the bare ends of the power supply to the +PWR and -PWR positions on pins 1
and 2 of screw terminal header J3 as shown in Figure 2. The polarity of your connec-
tions is not important because the power-supply circuit has a full-wave bridge rectifier.

2. Apply power.
Plug in the AC adapter. If you are using your own power supply, it must provide 9 V to
40 V DC or 24 V AC—voltages outside this range could damage the OP7200.
NOTE: A hardware RESET is done by unplugging the AC adapter, then plugging it back in.
You may also reset the OP7200 by grounding the reset input located on pin 5 of screw-terminal
header J10.
CAUTION: Unplug the power supply while you make or otherwise work with the connections
to the screw-terminal headers. This will protect your OP7200 from inadvertent shorts or power
spikes.
