Ama-Drainer 4../5..
NOTE
The highest point of the discharge line must be above the flood level (usually street
level) to prevent any backflow from the sewage system.
Transportable models
1. Connect the discharge nozzle to a hose with a suitable adapter (e.g. Storz
coupling).
Stationary installation

This pump is also suitable for stationary installation in a sump with a duckfoot
bend and guide wire or guide rail arrangement.
5.5 Electrical system
5.5.1 Information for planning the control system
NOTE
When laying a cable between the control system and the pump set's connection
point, verify that the number of cores is sufficient for the sensors. A minimum cross-
section of 1.5 mm² is required.
For the electrical connection of the pump set observe the wiring diagrams.
(
The pump set is supplied with power cables; it is wired for DOL starting.
The motors can be connected to low-voltage grids with nominal voltages and voltage
tolerances to IEC 38 or other power supply networks / power supply facilities with
maximum nominal voltage tolerances of ±10 %.
Variants SD and ND:
▪
To ensure complete separation from the power supply network and to prevent
the pump set from running on two phases only, fit an external 3-pole mechanical
interlocking device (e.g. 3-pole circuit breaker).
▪
To ensure the pump set is switched off in the event of excessive temperatures
connect the bimetal switch integrated in the winding to the control circuit. This is
mandatory if:
– The CEE plug type Hyper has been removed.
– The pump set has a free cable end.
– The pump set is connected to a control unit (e.g. LevelControl)
– For any third-party products, observe the maximum load of the bimetal
switch: V
CMAX
= 250 V AC, I
CMAX
= 1.6 A AC.
