NOTE
All field installation and wiring of electrical equipment
must be done to meet NEC, CEC and local codes.
Must use appropriately sized wire for the full load amp
draw.
When the hardwiring is complete, please refer to
the BMS Communication section for details on
communication via the hard wire connections.
The GJI fan requires single phase 208-277V
50/60 Hz power. Amperage ranges from 2.4 ~ 1.85A
depending on voltage. The motor also requires
either a 0-10VDC or MODBUS signal to control the
fan speed.
Particular attention should be given when connecting
power to the unit. Supply wiring must be properly fused
and conform to local and national electrical codes.
Two electrical knockouts are located on the back of the
unit (Figure 4). Utilize one knockout for motor power
supply and the second for control wiring. Each set of
wiring connections are to be run separately into the unit.
To access the wiring terminal strip, remove the electrical
access panel (Figure 5). Motor supply power and control
wires are connected to a terminal strip as shown in the
wiring diagram on the backcover (Figure 7).
After the electrical connections have been made secure,
reattach the access panel back into position.
