2.3 Main power Connection

The main power cable should be routed into the bottom left conduit entry.
Macurco recommends a minimum wire size of AWG18. The modular connector will accept wire from 12 to 24
AWG.
The safety ground wire should be secured to the ground stud at the bottom left of the cabinet with the lock
washer and nut supplied. Macurco recommends the use of a ring terminal for the ground connection.
Refer to Table 2-1 for DVP-120 power connections.
The line and neutral wires should be stripped 1/4 in. (6.5 mm), insert the wire into the wire cavity of the
modular connector and tighten the screw clamp. Ensure that the wire cannot be easily pulled from the
connector. Plug the modular connector into J4 on the PCB and ensure that it latches into the header properly.

2.4 Remote Sensor Connection

Each remote sensor is connected by a four-wire connection – two wires for DC power and two wires for the 4 –
20 mA loop connection. The sensors are connected to the control panel PCB with modular connectors, two
sensors per connector. See Figure 2-1 for a view of a typical sensor connector. Refer to Table 2-2 for wire size
recommendations.
