Note: The values apply to 230 V, 60 Hz, and conform to the requirements stated in the National Electrical
Code Book.
Note: Recommended maximum cable length between the SQE and the CU 300 or CU 301 control box =
650 ft.
6. Splicing the cable
The submersible drop cable can be ordered sepa-
rately in lengths of 25 to 300 ft, see section
17. Accessories.
The submersible drop cable supplied with SQE-NE
pumps is a 12 AWG ETFE cable with plug. It is not
recommended to splice this type of cable.
7. Fitting the cable guard
To fit the cable guard, proceed as follows:
1. Make sure that the motor lead lies flat in the
cable guard.
2. Place the cable guard in the groove in the cable
plug. The two flaps must engage with the upper
edge of the pump sleeve, see fig. 6.

strainer with the two self-tapping screws sup-
plied, see fig. 7.

8. Piping
• The pump should only be gripped by the two flats
at the top of the pump, see fig. 8.
• The pump can be installed vertically or horizon-
tally. During operation, the pump must always be
completely submerged in water.
• When plastic pipe is used, a stainless-steel safety
wire is recommended for lowering and lifting the
pump. Fasten the wire to the eyelet on the pump,
see fig. 9.
• The threaded joints must be well cut and fit
together tightly to ensure that they do not work
loose.
