CAUTION
Soaked packaging may tear!
The product may fall on the ground if unprotected and may be damaged. Lift wet
packaging carefully and replace it immediately!
5.3 Storage ▪ Pack the switchgear in dustproof and watertight packaging.
▪ Storage temperature: -30 … +60 °C, max. relative humidity: 90 %, non-condensing.
▪ Frost-proof storage at a temperature of 10 … 25 °C with relative humidity of 40 … 50 %
is recommended.
▪ Avoid the formation of condensation at all times!
▪ All open threaded cable glands must be sealed to prevent water ingress into the hous-
ing.
▪ Attached cables should be protected against kinking, damage, and ingress of moisture.
▪ To prevent damage to the components, protect the switchgear from direct sunlight and
heat.
▪ Clean the switchgear after storage.
▪ If there has been water ingress or condensation has formed, have all the electronic
components tested for correct function. Contact customer service!
6 Installation
▪ Check the switchgear for damage caused during transport. Do not install defective
switchgears!
▪ Observe the local guidelines for the design and operation of electronic controls.
6.1 Personnel qualifications ▪ Electrical work: A qualified electrician must carry out the electrical work.
▪ Installation/dismantling: The technician must be trained in the use of the necessary
tools and fixation materials for the relevant construction site.
6.2 Installation types
▪ Installation of the switchgear directly onto the pressure-boosting system
The switchgear is installed directly onto the pressure-boosting system at the factory.
▪ Wall fixation
If the switchgear needs to be separately installed on a wall, follow the instructions in
the “Installation” chapter.
6.3 Operator responsibilities ▪ The installation location is clean, dry, and free of vibrations.
▪ The installation location is overflow-proof.
▪ The switchgear is not exposed to direct sunlight.
6.4 Installation ▪ The connection cable and required accessories should be provided by the customer.
▪ While laying the cable, ensure that there is no tension, no kinking and no pinching that
could damage the cable.
▪ Check the cable cross-section and length for the routing type chosen.
▪ Seal unused threaded cable glands.
▪ Ensure that the following ambient conditions are adhered to:
– Ambient/operating temperature: 0 … 40 °C
– Relative humidity: 40 … 50 %
– Max. relative humidity: 90 %, non-condensing
6.4.1 Basic advice on fixing the
switchgear in place
Various structures can be used for installation (concrete wall, mounting rail, etc.). For
this reason, the fixation material for the relevant construction must be provided by the
customer and the following information must be observed:
▪ To prevent cracks in the masonry and chipping of the construction material, ensure suf-
ficient clearance to the edge of the structure.
▪ The depth of the borehole depends on the length of the screws. Drill the borehole ap-
prox. 5 mm deeper than the screw length.
▪ Drilling dust impairs retention force. Always blow the borehole clean or vacuum it out.
▪ Do not damage the housing during installation.
6.4.2 Installation of switchgear
Attach the switchgear to the wall with four screws and wall plugs:
▪ Max. screw diameters:
– Plastic housing: 4 mm (Control EC 2), 6 mm (Control EC 3)
– Steel housing: 8 mm
▪ Max. screw head diameter:
– Plastic housing: 7 mm (Control EC 2), 11 mm (Control EC 3)
