Danger of Electrical Shock when servicing an installed
unit.
ALWAYS DISCONNECT POWER SOURCE BEFORE
SERVICING! More than one disconnect switch may be
required.
Proper Wiring Size Selection and Wiring Installation
are the Responsibility of the Electrical Contractor.
Before bringing power to the unit check unit nameplate
to confirm it matches the voltage and phase of the
power you are supplying.
Remember that your field connections need to be
accessible for inspection.
Electrical Specifications
NOTE:
If your unit is equipped with ECM Motors, please refer to
“ECM Motor Manual Supplement for RenewAire Light Commercial
Units” for more detail.
Use conduit, strain reliefs, etc. as required by code to secure the
field wiring.
Electrical Options are identified on the Unit Label located near
electrical box on the outside of the unit. Find the complete Unit
Model Number in the lower left corner of the Unit Label. Use
the configuration chart to the left to determine motor power and
voltage installed in your EV450IN.
Follow these steps:
1.
Confirm the voltage of the power supply matches the unit.
2. Remove both unit access panels, i.e., the larger motor door
and small filter door.
3. Remove electrical box cover by removing two or three
screws. Connect the units power field wiring to the terminals
of the disconnect switch.
4. Connect service ground to ground wire pigtail.
5. Connect the control system to the pigtails in the control
voltage compartment of the units electrical box. Make
sure you are connecting the correct voltage, 24VAC, to the
control pigtails. See Control Wiring Schematics.
You must make sure to provide the correct voltage and
phase power supply. Installing the incorrect voltage and
phase will destroy the motor and possibly lead to injury!
