1. Loosen the screws on the top of both the motor terminal box and
the fan terminal box to remove the terminal box covers.
2. Remove the three screw plugs on one side of the two terminal
boxes.
3. Loosen the cable gland pre-assembled on the encoder cable.
Pass the encoder cable through the first threaded hole in the
motor terminal box housing. Follow the steps below to connect the
encoder cable to the motor terminal box:
3a. Insert the male connector of the encoder cable into the female
connector in the motor terminal box.
3b. Tighten the cable gland of the encoder cable onto the threaded
hole.
4. Pass the power cable through the cable gland, and then through
the second threaded hole in the motor terminal box housing.
Follow the steps below to connect the power cable to the motor
terminal box:
4a. Remove from the terminal box the three binding post nuts that
correspond to the power cable terminals U, V, and W. Place the
three terminal lugs at the end of the power cable conductors onto
the corresponding binding posts. Fasten the cable conductors with
the nuts. Remove the grounding screw for power terminal PE.
Place the terminal lug of the PE conductor on the grounding
screw, and then tighten the screw for the PE terminal.
4b. Tighten the cable gland of the power cable onto the threaded hole.
5. Pass your own fan cable (recommended cable outer diameter:
4 mm to 8 mm) through the cable gland, and then through the
threaded hole in the fan terminal box housing. Follow the steps
below to connect the fan cable to the fan terminal box:
5a. Loosen the four screws that correspond to the fan cable terminals
U, V, W and PE. Insert the terminal lugs at the end of fan cable
conductors into the corresponding sockets under the binding
posts, and then fasten the cable conductors with the screws.
5b. Tighten the cable gland of the fan cable onto the threaded hole.
6. Replace the covers of the terminal boxes, and then tighten the
screws respectively for the motor terminal box (4 x M5: max.
4.7 Nm) and the fan terminal box (4 x M4: max. 2.4 Nm).
