•
The controller contains ESD- (electrostatic discharge) sensitive parts and assemblies. Static control precautions
are required when installing, testing, servicing, or repairing the assembly. Component damage may result if
ESD control procedures are not followed. If you are not familiar with static control procedures, refer to
applicable ESD protection handbooks.
•
Stopping modes are not intended to be used as an emergency stop. The user is responsible for determining
which stopping mode is best suited to the application. Refer to the applicable standards for emergency stop
requirements.
•
Pump Stopping may cause motor heating depending on the mechanical dynamics of the pumping system.
Therefore, select the lowest stopping time setting that will satisfactorily stop the pump.
•
Slow Speed running is not intended for continuous operation due to reduced motor cooling.
•
The fan jumpers have been factory installed for 110/120V AC input. Refer to page 9 for 220/240V AC fan
wiring (5…480 A devices only).
•
Two peripheral devices can be connected to the DPI port. The maximum output current through the DPI port is
280 mA.
•
When installing or inspecting protective modules, make sure that the controller has been disconnected from the
power source. The protective module should be inspected periodically for damage or discoloration. Replace if
necessary.
•
An incorrectly applied or installed controller can damage components or reduce product life. Wiring or
application errors such as under sizing the motor, over sizing the controller, incorrect or inadequate AC supply,
excessive ambient temperatures, or power quality may result in malfunction of the system.
•
The Motor Overload parameter must be programmed by the installer to provide proper protection. Overload
configuration must be properly coordinated with the motor.
•
This product has been designed and tested as Class A equipment for EMC compatibility. Use of the product in
domestic environments may cause radio interference, in which case, the installer may need to employ
additional mitigation methods.
•
Disconnect the controller from the motor before measuring insulation resistance (IR) of the motor windings.
Voltages used for insulation resistance testing can cause SCR failure. Do not make any measurements on the
controller with an Insulation Resistance (IR or Megger) tester.
