Leave a short piece uncovered.
d) Check that the connected ground (earth) conductor has sufficient slack. The
conductor must stay connected even if the power conductors are pulled loose.
5. Prepare the power conductors:
a) Remove the aluminum foil around each power conductor.
b) Peel the insulation from each power conductor.
6. Prepare the ends of the ground (earth) conductor, the power conductors, and the drain
wire:
Connection type
Action
Screw
Fit cable lugs to the ends.
Terminal block
Fit end sleeves or leave the ends as they are.
4.6.5 Connect the cables: Standard pumps with MAS 801
This procedure must not be used for Ex-proof applications. If the pump is used in an Ex-
proof environment, then use the procedure that is described in
on page 42.
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.
For more information about the cable entry, see the Parts List.
1. Install the monitoring equipment. See the System Installation and Operation (SIO)
Manual for the MAS 801 monitoring equipment.
2. To connect the signal leads to the MAS BU, do the following:
a) Connect the two signal leads that are integrated in the SUBCAB
®
cable, T1 and T2, to
the MAS BU.
See the chapter “Installation” in the SIO Manual for the MAS 801 monitoring
equipment.
b) If it is not already connected, then connect the functional ground to the MAS BU.
3. To gain access to the terminal board, remove the entrance cover and the O-ring from the
stator housing.
4. If they are not already connected, then connect the T1 and T2 leads and functional
ground which are integrated in the SUBCAB cable to the PEM. See the illustration and
Terminals used in standard applications
on page 42.
5. Make sure that all thermal contacts or thermistors which are incorporated in the pump are
correctly connected to the PEM.
6. If they are not already connected, then connect the power leads:
a) Examine the data plate to see which connections are required for the power supply.
b) Arrange the connections to the terminal board in accordance with the required power
supply.
c) Connect the mains leads: L1, L2, L3, and ground (earth).
See the applicable cable chart.
The ground (earth) lead must be longer than the phase leads in the junction box of
the pump.
The following table shows how much extra length is required for the ground (earth)
lead.
Pump
Extra length of ground conductor, mm (in.)
7030, 7035, 7040
120 (4.8)
7. Make sure that the pump is correctly connected to ground (earth).
