Chapter 4 Routine Repair and Maintenance
The application environment (such as temperature, humidity, dust and powder, wool, smoke and
oscillation), burning and wearing of internal devices and other factors may increase the possibilities of
controller failure. To reduce the failures and prolong the service life the controller, it is necessary to
conduct routine repair and periodic maintenance.
Note:
1. Only the personnel receiving professional training can dismantle and replace the controller
components.
2. Prior to inspection and maintenance, please make sure that the power supply to the controller has
been disconnected for at least ten minutes or the CHARGER indictor is OFF, or there may be risks of
electric shock (the controller with power level of RS-P-4T11G/15L or above has CHARGER indicator).
3. Do not leave metal components and parts in the controller, or it may damage the controller.
