  • Page 4: Before You Begin

    DANGER HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH • Read and understand this manual before installing or operating the ER12 drive. Installation, adjustment, repair, and maintenance must be performed by qualified personnel. • The user is responsible for compliance with all international and national electrical code requirements with respect to grounding of all equipment.
  • Page 5 Before you begin WARNING LOSS OF CONTROL • The designer of any control scheme must - consider the potential failure modes of control paths and, for certain critical control functions, - provide a means to achieve a safe state during and after a path failure. Examples of critical control functions are emergency stop and overtravel stop.

    Before wiring power terminals, connect the ground terminal to the grounding screws located below the output terminals (see Access to the motor terminals if you use ring terminals, page 20. The drive must be grounded in accordance with the applicable safety standards. ER12 K/B drives have an internal EMC filter, and as such the leakage current is over 3.5 mA.
  • Page 15 Wiring WARNING RISK OF DRIVE DESTRUCTION • The drive will be damaged if input line voltage is applied to the output terminals (U/T1,V/T2,W/T3). • Check the power connections before energizing the drive. • If replacing another drive, verify that all wiring connections to the drive comply with wiring instructions in this manual. Failure to follow these instructions can result in death, serious injury or equipment damage.

  • Page 26 Internal EMC filter on ER12-...K/B All ER12-...K/B drives have a built-in EMC filter. As a result they exhibit leakage current to ground. If the leakage current creates compatibility problems with your installation (residual current device or other), then you can reduce the leakage current by opening the IT jumper as shown below.

  • Page 27: Check List

    • Wire the control terminals as required, see Control terminals on page 22. Separate the power cable and the control cable according to the EMC compatibility rules on page 25. • The ER12-...K/B range integrates an EMC filter. The leakage current can be reduced using the IT jumper as explained in the paragraph Internal EMC filter on ER12-...K/B on page 27.
