5.1.9 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 mains-
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: Mains supply
(terminals N, PE, L)
Group 4: Communication cable
(8-pin male socket)
- only
TPED
The communication cable is connected to the socket in group
4. The cable ensures communication between the two pumps,
whether one or two pressure sensors are connected, see
section
5.6 Communication cable for TPED pumps
The selector switch in group 4 enables changeover between
the operating modes "alternating operation" and "standby
operation". See description in section

Connection terminals - TPED
A galvanic separation must fulfil the requirements for reinforced
insulation including creepage distances and clearances specified
in EN 60335.
Note
If no external on/off switch is connected, connect
terminals 2 and 3 using a short wire.
