MAINTENANCE & INSTRUCTION BOOKLET
3. Use the schematic in section
for wiring. Unlock corresponding square clamping on the
terminal block by pushing the screwdriver on the diagonal trench. Insert one wire into the
clamp. By removing the screwdriver, the wire is fixed. Repeat this step with each additional
wire.
4. Important: Connect common wire (COM) and protective earth (PE) ground wire!
5. Remount the terminal block (C) with the two plastic screws (15) on the body (A). Turn plastic
screws by hand in the existing threads and tighten then by hand. Note: Use of plastic screws
is required because the minimum distance to the body (electrical safety) does not allow
metal screws.
6. The two closed mounting holes are made for the earthing of the Multipole PCB (B). Mount
the two screws (16) with the serrated lock washers. The serrated lock washers give a safe
contact even if the screws oxidise. Tighten the screws with the specified torque. If you are
using a power screwdriver consider the maximum speed allowed.
7. Insert the Multipole PCB (B) in the left groove of the left end plate and the modular sub-
bases. Check to make sure the plug-in connection on the PCB is centred with the orifice to
the valve interface.
8. Ensure connector-kit gasket is fitted on the left end plate.
9. Plug the terminal block (C) in the body (A) on the Multipole PCB (B).
10. Mount the body (A) with two mounting screws on the left end plate. Tighten the screws with
the specified torque. If you are using a power screwdriver consider the maximum speed
allowed.
