  • Page 9: Installation

    Installation Installation This chapter explains the installation location and installation methods of the driver, as well as how to install a load. The installation and wiring methods in compliance with the EMC Directive are also explained. Installation location The driver is designed and manufactured for installation in equipment. Install them in a well-ventilated location that provides easy access for inspection.
  • Page 10 Installing and wiring in compliance with EMC Directive Eff ective measures must be taken with regard to EMI caused by the DRL series actuator and/or driver in the control system equipment operating nearby and EMS of the DRL series actuator and/or driver. Failure to do so may result in serious impairment of the machine’s functionality.
  • Page 11 Installation  Notes about installation and wiring  Connect the actuator, driver and other peripheral control equipment directly to the grounding point so as to prevent a potential diff erence from developing between grounds.  When relays or electromagnetic switches are used together with the system, use mains fi lters and CR circuits to suppress surges generated by them.
