Electrical connections may only be performed by a qualified installer in compliance with current regulations.
Make sure that the type of mains power network, voltage and frequency are compatible with the ratings of
the station components shown on the respective rating plates. Provide suitable short circuit protection on
the supply line.
Before making electrical connections, read this operating manual, that of the station, of the electric pumps,
of the electrical panel, where applicable, and of the other station components, the instructions and any
electrical diagrams.
Before proceeding with any operations, make sure that all the connections (even those that are potential-
free) are voltage-free.
Unless otherwise specified in local bylaws, the supply line must be fitted with:
•
a short circuit protection device.
•
a high sensitivity residual current circuit breaker (30 mA) for additional protection from electrocution in case of inefficient
grounding.
•
a general switch with a contact aperture of at least 3 mm.
Fix the cables making sure they do not curve too tightly. Make sure the cables cannot be caught up in the electric pumps. Make sure
the liquid cannot enter the cables through capillarity. Thread the cables of the electric pumps and float switches through the relative
cable grommets and connect them to the electric panel.
Ground the system in compliance with current regulations. Connect the earth cable, if fitted, to the guide bar support and to the
crosspiece in the tank.
The inside of the tank is damp. Fit suitable electrical safety devices. Use suitably insulated joints.
Connect to the mains power supply.

the lock thread. Insert the metal lock tongue (3) into the square end of the lock, insert the screw and tighten to keep the tongue in
position. Use the supplied wrench (5) to turn the moving part of the lock so that the tongue does not slip out of the cover. Screw
the cover onto the tank (or extension) and turn the wrench to lock the cover. Remove the wrench and then insert the supplied
protective cover to prevent dirt from entering.
