2 Installation & Connection

2.1Mounting the DVP-120

Mounting holes are provided in the DVP-120 case at the four corners. The top two are keyhole shaped so that the panel can be hung and then the two bottom screws driven to hold the panel. Conduit entry holes are provided on the top, bottom and right side of the panel. The panel should be mounted with sufficient space all around, depending on the complexity of the installation.

Main power wiring should conform to national and local electrical codes, and may require separate inspections and certification. Contact your local building authority for further details. If safety certification is required to obtain your occupancy certificate, Macurco can contract to provide testing services to obtain certification (such as the ETL label) by a national testing laboratory. Contact the Macurco Sales Department for further details.

2.2General Wiring Information

WARNING

High voltage terminals (120/240 VAC) are located within the DVP-120, presenting a hazard to service technicians. Only qualified technicians should open the DVP-120 case and service the internal circuits. Ensure power is removed from the DVP-120 prior to servicing the unit.

With the exception of the safety ground, all field wiring is done via modular connectors (provided) so that the wiring can be done easily and then simply plugging the modular connectors into the matching connectors on the PCB.

The power and signal connections to the remote mounted sensors should be size AWG18 (minimum) for short runs. Refer to Table 2-2 for recommended wire gauges. Four conductor cables may be used in all cases since the DVP-120 employs DC power for remote sensors to prevent electrical noise from interfering with the sensor output signal.

Do not bundle sensor power and/or signal connections with other AC power cables to prevent electrical interference. If other AC power connections must be bundled with the DVP-120 sensor cables, Macurco recommends that the sensor connections be made with two twisted pairs of the appropriate gauge, with an overall foil and braid shield. All shields should be terminated at the DVP-120 end of the cable only. A ground stud is provided near the bottom left corner of the panel.

Typical part numbers for AWG18 are:

–Alphawire 55132

–Belden TBD
