Determine how to power the MicroMax interrupter using one of these possible sources:
1.
Internal battery.
2.
Rectifier - with power turned on to the rectifier, use a voltmeter to locate a power source
across two available AC taps. The interrupter requires 8-42 V AC or 10-60 V DC.
3.
A 120 V AC convenience outlet to use with the 12 V DC wall adapter.
4.
A DC source, such as a 10-60 V DC battery.
5.
A USB cable connected to a computer.

NOTE:
If available, use line power to power the GPS360 to save the internal battery power.
Connecting the Built-in Relay to a Rectifier
The GPS360 includes a built-in relay. You can also connect the GPS360 to an external relay. Refer to
Mercury Relay Advisory on page 61
if working with a mercury relay.
NOTE:
If you will be installing the GPS360 on a
bond
, the relay wires must be connected in series
with the two structure wires, one from each of the pipelines.
1.
Turn
OFF
all power to the rectifier.
2.
Connect the interrupter's relay cables to the rectifier, depending on what you will be
interrupting.
