, 50/60 Hz. Power should be connected to the Power Input Terminal TB1 and

the Ground screw. See Figure 4 for location. Instrument is supplied with a strain relief and a standard U.S. 3 prong power line

cord.

For DC wiring 24V

may be wired to J12, (J12-1)position 1 + with ground connected to (J12-2)position 2.

Upon supplying power to the AM-5175:

 The green power on LED is lit.
