2.1.1 Mounting the housing box
On delivery of a complete drive unit (gear unit + motor + frequency inverter) SK 1x5E motor starters are
always fully installed and tested.
NOTE
Mounting of an IP66-compliant SK 1x5E must be carried out by NORD as special measures
have to be implemented. IP66 components retrofitted on site cannot ensure that this protection
class is guaranteed.
When delivered separately, the motor starter includes the following components:
·
Motor starters
·
Screws and contact washers for mounting the motor terminal box.
·
Pre-fabricated cable for motor and PTC connections
Procedures:
1. If necessary, remove the original terminal box from the NORD motor, so that only the base of the
terminal box and the terminal strip remain.
2. Set the bridges for the correct motor circuit and connect the pre-fabricated cables for motor and PTC
connections to the respective connection points on the motor.
3. Mount the cast housing on the terminal box base of the NORD motor using the existing screws and seal
as well as the enclosed toothed / contact washers. Position the cast housing with the dome facing the
A-side of the motor (looking towards the A bearing cover). Check the adaptability for different motor
manufacturers.
If necessary, the plastic cover (1) for the electronics must be carefully removed in order to make the
screw fastenings to the base of the terminal box.
4. Connect the motor cables U, V, W to the power terminal block and the PTC cable TF+, TF- to the control
terminal block 38, 39.
