The supply voltage and FLA will be noted on the nameplate. The
blower and pulse cleaning system controls are factory pre-wired
for operation. The touchscreen controls are also pre-wired for the
integral option, but require field wiring and connections for the
remote display enclosure option. Wiring diagrams for the various
SHM controls, blower arrangement and supply voltage options are
available within the appendix of this manual. Note that the SHM
does not contain the main disconnect or fuses for the supply power.
Electrical installation should be completed by a qualified professional
and done in accordance with all applicable codes and regulations.
Power cord and connection into unit will be supplied by the cus-
tomer.

SHM Voltage and Full Load Amps
Note: When making the main power connections to the unit,
fan rotation check is not required.
3.5.1 Electrical Power Supply
The main power supply is connected to the SHM 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 con-
nection. The rear electrical panel also contains the unit circuit break-
ers 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
Machine Interlock 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 addi-
tional wiring information.

3.5.2 Electrical Basic Controls
The basic electrical controls consist of a thermal motor protec-
tion disconnect on the side of the unit. This is set for the FLA of
the single blower motor. This is factory prewired to the blower
motor. When installing this unit in the field the customer will con-
nect their factory power to the disconnect on the line side of the
thermal protector. The disconnect On/Off will supply power to
the unit and allow the blower On/Off switch on the front of the
unit to control the blower. Inside the door on the front of the unit
there is a blower speed adjustment. This will control the speed
of the blower from off to full speed. This should be adjusted by
the customer to meet their process requirements.
3.5.3 Electrical Touchscreen Controls
The main control panel for the SHM unit is a touchscreen interface
located integrally on the front of the unit or remotely in an auxiliary
enclosure (refer to section 3.5.4) that operates the blower.
The touchscreen control panel is powered by 24V DC. Refer to
Section 4 of this manual for operation of the touchscreen. All wir-
ing 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.
3.5.4 Electrical Remote Panel Controls
Both the Basic and Touchscreen Controls can be mounted
remotely from the unit. The max distance is 100 FT (30.5 m).
The controls are provided in a NEMA 4X enclosure for mounting.
