Installing EI7. – DRN../DRU../DR2..71 – 132S motors

Before installation, the grommet [1526] with part number 13637339 must be obtained from SEW-EURODRIVE.

The grommet [1526] is also included in the respective retrofit sets and service kits.

Before installation, the flat-head screws for the brake [1518] with part number 19103387 must be obtained from SEW-EURODRIVE.

The screws [1518] are also included in the respective retrofit sets and service kits.

Before installation, a terminal washer [1524] with part number 13262130 must be obtained from SEW-EURODRIVE.

The terminal washer [1524] is also included in the respective retrofit sets and service kits.

  • Push the grommet [1526] onto the cable end of the encoder module [1517]. The inside diameter of the grommet may not exceed the maximum inner diameter of 12 mm.

  • Cable jacket with cable lubricant, for example: Coat LuB-I of 3M™. Using a rotating movement, carefully pull the cable through the grommet into the terminal box. While doing so, ensure that the grommet does not inadvertently slide through into the terminal box.

The minimum bending radius of 28 mm must be observed.

  • Prepare a warming plate.
  • Place the bushing of the plastic fan on a warming plate and heat it up to a temperature of 100 to 130 °C.

While doing so, ensure that the plastic fan does not come into direct contact with the warming plate.

Any thermally conductive component [1] (e.g. a metal ring) can be used as a contact surface.

  • Apply assembly paste to the shaft/fan seat e.g.: MOLYCOTE®.
  • Install the warmed fan.
  • Fasten the fan using a retaining ring.

  • Mount the fan guard and fasten it with screws.
    • Tightening torque for metal fan guard: 3.3 Nm
    • Tightening torque for plastic fan guard: 2 Nm

  • Mount the terminal box cover and fasten it with screws.
    • Tightening torque: 4 Nm

  • Fasten the encoder module to the spacers using 2 screws [1518].
    • Tightening torque: 2.5 Nm
