Electrical Connections - Greenheck Vektor-H Installation, Operation And Maintenance Manual

Electrical Connections

NOTE
Refer to the Vektor Laboratory Exhaust with Variable
Geometry Nozzle (VGN) Technology Electrical
Controls Installation, Operation and Maintenance
Manual for electrical wiring and connection
information.
Before electrical connections are made, the supply
voltage, phase and ampere capacity must be checked
for compatibility with the fan motor. In addition, the
supply wiring must be properly fused and conform to
local and national electrical codes. If unit is supplied
with a safety disconnect switch, ensure proper wiring
to the fan motor. Be sure the disconnect is switched to
the "OFF" position before connecting supply wires. If
no disconnect is supplied, ensure the supply wire is not
live before connection. Supply wires are then connected
to the optional safety disconnect switch (if supplied) or
motor.
Vektor-H Motor Disconnect and Isolation Damper
Wiring Diagram
Disconnect is mounted to fan housing. Transformers are
mounted to bypass air plenum with damper actuator
motors. For systems that ship unassembled because
of physical size, this connection at disconnect from
transformers must be field-installed. Wires with conduit
and fittings are provided pre-connected to transformers.
