Figure 10: Copper foil on control element.
b) Put a white shrink hose over the drain wire and the cable terminal.
c) Fit a cable lug on the drain wire.
d) Twist T1+T2 and T3+T4.
e) Put a shrink hose over the control element.
Make sure that the conductive copper foil and drain wire is covered.
3. Prepare the ground (earth) core for SUBCAB
™
cable:
a) Peel the yellow-green insulation from the ground (earth) core.
b) Check that the ground (earth) core is at least 10% longer than the phase cores in
the cabinet.
c) If applicable, put a cable lug on the ground core.
4. Prepare the ground (earth) core for screened SUBCAB
™
cable:
a) Untwist the screens around the power cores.
b) Put a yellow-green shrink hose over the ground (earth) core.
Leave a short piece uncovered.
c) If applicable, put a cable lug on the screened ground core.
d) Twist all power core screens together to create a ground (earth) core and
fit a cable
terminal to the end.
e) Check that the ground (earth) core is at least 10% longer than the phase cores in
the cabinet.
5. How is the connection to ground (earth) made?
– Screw: Fit cable terminals to the ground (earth) core and the power cores.
– Terminal block: Leave the core ends as they are.
6. Prepare the main leads:
a) Remove the aluminum foil around each power core.
b) Peel the insulation from each power core.
4.2.2 Connect the motor cable to the pump
NOTICE:
Leakage into the electrical parts can cause damaged equipment or a blown fuse. Keep
the end of the motor cable dry at all times.
1. Remove the entry gland screw from the stator housing.
2. Remove the stator housing.
This provides access to the terminal board/closed end splices.
3. Remove the terminal board.
4. Check the data plate to see which connections are required for the power supply.
5. Arrange the connections on the terminal board/closed end splices in accordance with
the required power supply.
6. Connect the mains leads (L1, L2, L3, and ground (earth) ) according to applicable
cable chart.
