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.
