Power connection
Cable glands
Cable glands comply with EN 50626.
• 1 x M40 cable gland
• 1 x M20 cable gland
• 2 x M16 cable gland
• 2 x M16 knock-out cable entries.
Grid types
Three-phase E-pumps can be connected to all grid types.
6.3.8 Start/stop of pump
When the pump is switched on via the power supply, it will start
after approx. 5 seconds.
If a higher number of starts and stops is desired, use the input for
external start/stop when starting/stopping the pump.
When the pump is switched on via an external on/off switch, it will
start immediately.
6.3.9 Connections
As a precaution, the wires to be connected to the following
connection groups must be separated from each other by
reinforced insulation in their entire lengths:
Group 1: Inputs
• start/stop
terminals 2 and 3
• digital input
terminals 1 and 9
• setpoint input
terminals 4, 5 and 6
• sensor input
terminals 7 and 8
• GENIbus
terminals B, Y and A
All inputs (group 1) are internally separated from the power-
conducting parts by reinforced insulation and galvanically
separated from other circuits.
All control terminals are supplied with protective extra-low voltage
(PELV), thus ensuring protection against electric shock.
Group 2: Output (relay signal, terminals NC, C, NO)
The output (group 2) is galvanically separated from other
circuits. Therefore, the supply voltage or protective extra-low
voltage can be connected to the output as desired.
Group 3: Power supply (terminals L1, L2, L3)

Connection terminals
A galvanic separation must fulfill the requirements for reinforced
insulation including creepage distances and clearances specified
in EN 61800-5-1.

Warning
If the supply cable is damaged, it must be
replaced by qualified personnel.
Warning
Do not connect three-phase E-pumps to a power
supply with a voltage between phase and ground
of more than 440 V.
&DXWLRQ
The number of starts and stops via the power
supply must not exceed 4 times per hour.
