4. When using the subplates mentioned in
or in case of assembly on comparable cast
iron installation surfaces, tighten all four valve mounting
screws with a torque power screwdriver (tolerance ≤ 10 %)
and a tightening torque of 7 Nm (5.2 ft-lbs) +/– 10 %.
This tightening torque refers to the maximum admissible
operating pressure.
DANGER
Check the structure of the valve using the circuit dia-
grams, device lists and assembly plans.
Clarify possible differences with the responsible
persons.
5. Make sure that pipes and/or hoses are connected to all
ports and/or that the ports are sealed with plug screws.
6. Carry out a special check to make sure that the cap nuts
and flanges are correctly tightened at the pipe fittings
and flanges.
IMPORTANT
Mark all checked fittings, e.g. using a permanent marker.
7. Make sure that all pipes and hose lines and every com-
bination of connection pieces, couplings or connection
points with hoses or pipes are checked for their opera-
tional safety by a person with appropriate knowledge
and experience.
6.4 Establishing the electrical connection
CAUTION
Mating connectors for valve solenoids with a terminal
box may only be connected by or under the supervision
of a specialized electrician.
De-energize the connection line prior to assembly.
Use finely stranded conductors only if they have
pressed-on wire end ferrules.
Strip the wires of the connection lines and the protec-
tive grounding conductor with 5 + 1 mm. Strip the wires
of the external equipotential bonding with 9 + 1 mm.
Use only lines satisfying the requirements on the termi-
nal areas of the connection terminals, see "
Data sheet
".
The maximum temperature of the valve casing surface
is 125 °C. This has to be considered when selecting
the connection cables and/or contact of the connection
cable with the casing surface is to be prevented.
Connect the protective earthing conductor and the
earthing properly.
Avoid sharp bends in connection lines and litz wires to
prevent short-circuits and interruptions.
When using a finely stranded conductor, equip it with
wire end ferrules. The lines used have to be suitable
for ≤ –20 °C to
≥
+100 °C.
All types have to be equipped with an internal protective
grounding conductor terminal and an external ground-
ing terminal.
At the factory, the valve is fitted with an adapter for
a cable entry and it guarantees type 4 according to pro-
tection class NEMA 250.
The cable entry is provided by the customer and also
has to comply with type 4 according to protection
class NEMA 250.
Adapter connection data:
Internal connection thread
1/2" NPT
IMPORTANT
When mounting the customer's cable entry, the adapter is
to be held in place with a suitable tool (hexagon wrench,
wrench size 27).
The connection is polarity-independent. In case of a valve
solenoid to be connected to AC voltage, a bridge rectifier is
integrated in the valve solenoid.
1. Open the terminal box (internal hexagon, wrench size 3).
2. Guide the cable through the adapter into the terminal box.
3. Connect the wires of the connection line to the 2 pin con-
nection terminal and the internal protective grounding
conductor terminal.
4. Make a connection to the external equipotential bond-
ing line.
Tightening torques for the clamping screws:
Operating voltage connection
0.4...0.5 Nm
Connection for protective
earthing conductor
1.0...1.2 Nm
Connection for potential
equalization conductor
2.0...2.4 Nm
5. Mount the cover with the seal beneath it.
Tighten the mounting screws (internal hexagon,
wrench size 3) with spring washers diagonally, one after
the other.
Tightening torque of the cover screws: 1...1.1 Nm.
