Installation
Figure 6 - Electrical supply connection, three-phase motors, 380-415 V 50 Hz, or 460 V 60 Hz
We recommend that you connect the electrical supply to the motor through a starter or circuit breaker which has
thermal over-current protection which can be adjusted to suit the full-load current ratings shown in
Table 2 . The
fuse ratings in Table 2 are provided for guidance only. The supplier of your thermal over-current protection device
may specify different values to ensure correct operation of the over-current protection device. Ensure that the fuse
you use is suitable for the starting currents given in
Table 2 .
1. Remove the cover from the motor terminal box.
2. Check your electrical supply voltage and frequency. If necessary, configure the motor to operate with your
electrical supply (see Figures 5 and 6 ).
3. Remove the 20 mm diameter plugs from the cable-entry hole that you will use for the electrical supply cable.
Choose the most suitable hole for your application.
4. Fit a suitable cable-gland and nut to the entry hole. After the supply cable is fitted, the cable-gland must be a
protective seal to the standard of IP44 in IEC 529 or better.
5. Pass the motor electrical supply cable through the cable-gland.
6. Connect the cables o the terminals as shown in Figures 5 and 6 .
