DUSTHOG PNP Series
3.4.1 Electrical Supply Power
The main power supply is connected to the PNP unit through a 1˝ FNPT coupling located on the rear
of the unit shown in Figure 1B. After feeding wires through the coupling, terminations are made on
the main bus bar terminal for each phase and frame ground connection. The rear electrical panel also
contains the unit circuit breakers and DC power supply for the controls components. Utilize Table 1
for wire, fuse and disconnect sizing for your respective product model. A second plugged 1˝ FNPT
coupling is also located on the rear of the cabinet for low optional voltage connections using the
process control feature to automate operation. Ensure that the rear electrical panel cover is in place
and secured prior to operating the unit. Refer to the electrical wiring diagrams in Table 2 for additional
wiring information.
Note: When making the main power connections to the unit, fan rotation check is not required.
The blower will automatically turn in the correct direction.

3.4.2 Electrical Touchscreen Controls
The main control panel for the PNP unit is a touchscreen interface located integrally on the front of
the unit or remotely in an auxiliary enclosure (refer to section 3.4.3) that operates the blower and filter
pulse cleaning system. Both the touchscreen control panel and filter pulse cleaning valves are powered
by 24V DC. Refer to Section 4 of this manual for operation of the touchscreen. All wiring in the
touchscreen controls panel is pre-wired at the factory and there are no customer connections at this
panel. The panel door should remain closed and locked during operation.
3.4.3 Remote Controls Panel
The PNP unit is available with a remote controls panel that allows touchscreen controls to be located
within 100 ft. (30.5 m) from the PNP unit location. The controls are provided in a NEMA 4X enclosure
for mounting. The remote display panel will come pre-wired with two cables, one is the 24 VDC power
supply, along with control cables and the other is a communications cable that must be connected
to the PNP unit upon installation. Note that these wires are low voltage and should not be run next to
high voltage wires. These wires should be cut to final length at installation.
