7.1 standard model
→
Connect L1/+ and N/– to terminals 1 and 2, independent of the
polarity.
→
Connect protective conductor.
→
Attach seal and check for correct fit.
→
Tighten cable plug (Type 2508 or 2509 in accordance with DIN EN
175301-803 (DIN 43 650), shape A, for order numbers see data
sheet); while doing so, observe the maximum torque of 1 Nm.
→
Check electrical continuity between coil and body (protective con-
ductor function).
7.2 pulse model (cf 02)
In accordance with the terminals on the valves, the connection
terminals in the cable plug are marked with the numbers 1 to 3.
→
Connect as shown in "Fig. 4". Pulse on terminal 1 closes the valve;
pulse on terminal 2 opens the valve.
→
Attach seal and check for correct fit.

and vent/drain lines.
Risk of injury due to electrical shock.
▶ Before working on the system or device, switch off the power
supply and secure to prevent reactivation.
▶ Observe applicable accident prevention and safety regulations
for electrical equipment.
WarnIng!
Risk of injury from improper disassembly.
▶ Disassembly may be carried out only by trained technicians and
with the appropriate tools.

note!
▶ Prevent simultaneous pulsing on both coil windings.
▶ Parallel to the terminals, no other consumers (relay, etc.) may be
connected.
▶ The respective coil connection that does not carry current must be
galvanically isolated (open).
▶ In case two or more valves are connected in parallel, the use of two-
pole or multi-pole switches must ensure that this requirement is met.
