P266 Series Single-Phase Condenser Fan Speed Control Installation Instructions
2
Wiring
Refer to the model-specific wiring diagram located on
the interior label of the P266 Series control and
observe these guidelines when wiring the P266 Series
control:
•
Ensure that the wires between the P266 Series
control and the fan motor do not exceed 15 m
(50 ft).
•
Wires connected to the line-voltage terminal block
must be 3.31 mm
2
(12 AWG) or smaller.
•
Low-voltage wires must be less than 30 m (100 ft).
!
WARNING: Risk of Electric Shock.
Disconnect or isolate all power supplies
before making electrical connections.
More than one disconnect or isolation
may be required to completely
de-energize equipment. Contact with
components carrying hazardous voltage
can cause electric shock and may result
in severe personal injury or death.
IMPORTANT:
Do not connect supply power to the
P266 Series control before finishing wiring and
checking all wiring connections. Short circuits or
improperly connected wires can result in damage to
the P266 Series control and void any warranty.
IMPORTANT:
Do not exceed the P266 Series Fan
Speed Control electrical ratings. Exceeding P266
Series control electrical ratings can result in
permanent damage to the P266 Series control and
void any warranty.
IMPORTANT:
Use 60/75 C copper conductors only.
Make all wiring in accordance with local, national,
and regional regulations.
IMPORTANT:
Electrostatic discharge can damage
P266 control components. Use proper Electrostatic
Discharge (ESD) precautions during installation and
servicing to avoid damaging P266 components.
