Additional Spring Hanging Isolator
If a hanging spring isolator such as a Kinetics SH is
needed, a section of the hanging rod, as illustrated
in the section above, can be replaced with the
spring isolator housing. Follow the manufacturer’s
recommended installation procedures.
Electrical and Controls Connections
NOTE
Verify blower motor voltage matches line voltage 110-
120V 50/60 Hz, 208-230/277V 50/60 Hz.
Soft start
All motors feature soft-start technology which eliminates
inrush current at start-up. The motors will reliably start
at any speed setting.
Overload protection
If the motor becomes overloaded, it will automatically
reduce its speed until it is no longer overloaded. This
means that the motor will never operate in the “service
factor” which is possible with many AC motors.
Installation Instructions
Fig. 1 Both ends of the
strip are bent over 8-10 cm.
Protect your hands with

bracket.
Fig. 3 Hang on threaded rod
or ceiling bracket.
Note 1 The speed control dial is located on junction box. Turn dial for speed adjustments to motor.
Note 2 0-10 VDC fan motor control by others for 0-10 input, speed control dial must be set to 0.
• 0-1.9 VDC fan motors are off
• 2 VDC - minimum speed
ON threshold (from previous OFF) - 2 VDC
OFF threshold (from previous ON) - 1.5 VDC
• 10 VDC - Maximum speed
Vari-Green

Motor
The QEID FJ utilizes a Vari-Green
®
motor. The Vari-
Green motor is an electronically commutated (EC) motor
that uses AC input power and internally converts it to
a DC power supply which provides an 80% turndown
capability and increased energy savings.
