Electrical Connection; Assembling The Exterior Switch Cabinet - Graf KLARO Easy Notice D'installation

7. Assembling the exterior switch cabinet

7.1 Selecting the location
The location must be cool and protected from direct sunlight during the summer months. The rear side of
the round column/the sides of the cabinet must be installed with at least 10 cm clearance from the nearest
wall. If shading is provided for on-site, this must be located on the rear side or on the sides, leaving open
space so that the column/cabinet is sufficiently ventilated and in order to avoid trapped heat.
Height above the highest water level in the tank in order to avoid overflow and water intake in

the open channel in the event of an accident.
The machine cabinet requires a separately protected electrical connection (16 amp, slow

blow). Additional electrical fixtures on the same fuse may disrupt operation.
The system generates noise! When operating, the air compressor generates continuous

noise comparable to a freezer.
The air hoses must be no longer than 20 metres.

7.2 Installation
A sufficiently wide and deep ditch should be provided at the planned
location. The foundation base for cabinets is to be assembled according
to the accompanying assembly instructions. The empty pipe and the air
hoses must be routed into the prepared ditch. The base is then to be
inserted vertically into the ditch to a depth of approx. 60-64 cm.
Make sure that the cabinet is stable and secure and is installed vertical-
ly in the ditch.
For work in the lower part of the exterior column, the spacer under the
door can be removed.
Unlock the door, pull it forwards and remove it in an upwards di-

rection (image A).
Pull the intermediate piece upwards and remove towards the

front (image B).
To reduce earth moisture, fill the empty space inside the base with appropriate base filling granulate (art.
no. 107607). The filling material can remain in the cabinet base permanently and does not need to be
changed.
The granulate filling volume for a filling height of approx. 30 cm corresponds to:
Exterior column:

A cabinet open to the surrounding ground may result in corrosion damage on
the electrical components in the event of high levels of ground moisture!

Electrical connection

The electrical connection of the switch cabinet must only be carried out by a
qualified electrician!
An underground cable must be laid to supply power to the cabinet. This cable must
be protected by a 16 amp fuse via the building installation and must be able to
be separated from the mains.
Fuse
The underground cable is connected to the pre-assembled power socket in the cabi-
connections
net.
