3. Installing the cabinet in the earth
The black venting outlet is to be fitted onto the cover of the cabi-
net.
An adequately large trench is to be dug, with the installation
depth of the cabinet being 35 cm. The cabinet is then placed in
the trench. As backfill material, only cohesive excavated soil
may be used, free of any stones. In the event of the excavated
material being unsuitable, round grain gravel (maximum granu-
lation 8/16) is to be used.
Care must be taken to ensure that the cabinet is standing firmly
and vertically upright in the excavation.
3.1 Connecting the empty technical supply pipe to the clarification system
The empty technical supply pipe is connected via a pipe plug
with rated diameter of 110 to the socket provided for this pur-
pose.
3.2 Introducing the earth cable for the power supply
The power cable is to be introduced into the cabinet by way of a M10x1.5 cable screw connection (suita-
ble for cable diameters of 8-13 mm).
A drill hole with diameter of 20 mm is to be provided for this purpose.
3.3 Electrical connection
Provide fuse for
the connection
The electrical connection of the switch cabinet may only be carried out by a
qualified electrician.
The power supply requires an earth cable to be laid to the cabinet.
This cable must
be fused with a 16 Amp fuse via the in-house installation, and must be capable
of being isolated from the mains network.
The connection for the control unit must be provided via a fused contact coupling to
be provided by the client.
