1.1.6 Maintenance
Notice:
All the instruction photographs and diagrams of opened controller in this manual are only for
illustration. Do not attempt to operate any AC controllers with the cover opened.
1.2 Warning Label
The warning label is on the front of the controller. Please read it carefully and follow the
instructions.
Read the user manual before operation.
Risk of electrical shock. Shut off main power and wait for 5 minutes before servicing.
Hot surface. Risk of burn.
Ensure the and equipment are in proper use before operation. Failure to; comply could damage the
equipment.
The temperature of the braking resistor and heatsink could be very high during operation. Do not touch it
or it could result in scald.
For lift applications, please install mechanical brakes.
Adjust a few parameters only if necessary as the defaults are optimum settings for most of applications.
Editing parameters indiscriminately could cause equipment abnormal operation.
Interlock the electricity supply with AC controller supply when both are available to a load.
Danger
Do not touch the main circuit of the controller when power is on. Failure to comply could cause electrical
shocks.
Disconnect the power supply before opening the front cover of the controller.
Maintain the controller only when the CHARGE indicator light is off or 5 minutes after turning off power
supply, so as to avoid charged capacitors causing physical injury.
Allow only qualified electric engineers and electrician to maintain, repair and replace the AC controller
modules.
Warning
The release of breaker on the AC controller primary side could be caused by incorrect wiring, short circuit
and damaged controller components. Investigate and remove the problem before reconnecting the
breaker.
Do not use a megger (insulation resistor) to test the controller control circuit. Failure to comply could cause
controller damage.
