s&h ecm pump motor with user interface
1 perfectspeed® motor
The PerfectSpeed® ecm user interface developed by Arm-
strong easily integrates into non-communicating systems
using state-of-the-art technology. The motor is a high-efficient
Brushless dc (bldc) permanent magnet motor that offers
variable speed. Sensorless sine wave control assures quiet and
ultra-smooth performance.
important safety information
warning
shock hazard
To reduce the risk of fire or electric shock:
• Do not expose the motor or control unit to rain or
moisture.
• Do not separate the motor and control unit while
the motor is in operation.
warning
• Only trained and qualified professionals familiar
with PerfectSpeed® motors should service the mo-
tor and control unit.
• Before connecting or disconnecting cables or other
electrical connections, verify that the power to the
system is removed. Failure to comply may cause
serious damage to the motor or injury to personnel.
• Because of the risk of electric shock, only individu-
als thoroughly trained in the use of multimeters
should conduct voltage tests.
• Never touch the metal contacts on the multimeter
during a test.
• Always check testing equipment for proper opera-
tion before use.

warning
Installation, operation, and maintenance must be
performed by qualified personnel. Familiarization with
and adherence to the National Electrical Code (nec)
and National Fire Protection Association (nfpa) standards and
to local codes are required. It is important to observe safety
precautions to protect personnel from possible injury. Person-
nel should be instructed for handling each of the following:
• Insulate all connections carefully to prevent grounding or
short circuits. Reinstall all conduit and terminal box covers.
To avoid overheating and loss of performance, voltage to
the motor control unit must be within plus or minus 10% of
the nameplate voltage.
• Make sure the unit is electrically grounded and that proper
electrical installation wiring and controls are used consis-
tent with local and national electric codes. Refer to National
Electrical Code Handbook and nfpa No. 70. Employ
qualified electricians.
• Code requirements differ from state to state. Install equip-
ment in accordance with the applicable codes and ordinanc-
es in your area and in accordance with nec. All electrical
connections should be made and maintained by a qualified
or licensed electrician.
• Make sure there are no unusual noises or vibrations when
the motor is running.
• If noise and vibration are observed, refer to the appropriate
Troubleshooting section.
• Avoid contact with energized circuits or rotating parts.
• Provide proper safeguards for personnel against rotating
parts.
• All aspects of the installation must conform to the applica-
ble requirements of the nec, including Article 430 (Motor
Circuits and Controllers), as well as all local codes.
warning
Always disconnect electrical power at the fuse box or
circuit breaker before handling electrical connections
or performing maintenance on this unit. Allow the
motor to come to a complete stop and wait four (4)
minutes. This allows the capacitors to discharge any
residual voltage for safety.
Double-check to make sure the power is removed,
and that it is locked out while you are working on
the equipment.
