ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your MPC-122-K.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your
equipment.
Temperature Caution!
Be careful when handling the unit. When the unit is plugged in, the internal components generate heat, and
consequently the outer casing may feel hot to the touch.
Connecting the Power
The MPC-122-K offers 18 to 36 VDC power input with the terminal block. If the power is supplied properly, the
Power LED will light up. The OS is ready when the Ready LED glows a solid green.
For safety reasons, please use cables with the following specifications:
Wire range 14-22 AWG, torque 7 lb
Grounding the MPC-122-K
Grounding and write routing help limit the effects of noise due to electromagnetic interference (EMI). Run the
ground connection from the ground screw to the grounding surface prior to connecting the power.
ATTENTION
This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel.
EG: See the figure shown below for the location of the Earth Ground on the terminal block power connector.
Connect the EG wire to an appropriate grounded metal surface.
