3.1 Unpacking
1Visually inspect the transport packaging for signs of external damage
2Unpack the Multi-Channel Controller and put the packaging material
aside
Note:
Keep the packaging material for later use. The Multi-Channel Controller
must be stored and transported in the original packaging material only.
3Examine the Multi-Channel Controller for completeness
4Visually inspect the Multi-Channel Controller for signs of damage
Damaged product.
Putting a damaged product into operation can be extremely dangerous.
Never attempt to put a damaged product into operation. Secure the dam-
aged product from unintended operation. Send a damage report to the
haulage company or the insurer.
3.2 Mechanical installation
The Multi-Channel Controller can be used as follows: As a desk-top unit,
mounted in a control panel, or mounted in a 19" rack. In each of these cases
you must pay attention to the following safety note:
Too high ambient temperature.
Exceeding the maximum permitted ambient temperature may damage the
unit.
Make sure that the maximum permitted ambient temperature is not ex-
ceeded and that the air can flow freely through the louvers. Do not expose
the unit to direct sunlight.
3.2.1 Desktop unit
In order to use the Multi-Channel Controller as a desk-top unit, proceed as fol-
lows:
1Turn the Multi-Channel Controller upside down as shown in Fig. 3-1,
16
2Push the supplied rubber strip onto the lower edge of the front panel
3Stick the supplied rubber feet to the bottom of the casing

3.2.2 Control panel mounted
In order to mount the unit in a control panel, the following cutout is required:
Fig. 3-2 Control panel cutout (in mm)
1Insert the Multi-Channel Controller into the cutout
2Fasten the unit with four M3 screws
Note:
In order to reduce the strain on the front panel it is recommended to sup-
port the bottom of the unit.

3.2.3 Mounting the unit in a rack
The Multi-Channel Controller is designed for installation into a rack chassis
adapter according to DIN 41 494 (19", 3 HE). For this purpose, 4 collar screws
and 4 plastic sleeves are supplied with the unit.
Lower protection class of the rack.
If the product is installed in a rack, it is likely to lower the protection class
of the rack (protection from foreign bodies and water) e.g. according to the
EN 60204-1 regulations for switching cabinets.
Take appropriate measures to restore the required protection class of the
rack.
Fig. 3-3 Mounting the unit in a rack
Note:
In order to reduce the strain on the front panel it is recommended to
equip the rack chassis adapter with a guide rail.
Note:
For safe and easy installation of heavy rack chassis adapters, it is rec-
ommended to equip the rack frame with slide rails.
1Fasten the rack chassis adapter in the rack
2Insert the Multi-Channel Controller into the rack chassis adapter
3Fasten the Multi-Channel Controller with the supplied collar screws and
plastic sleeves to the rack chassis adapter

3.3.2 Mains connection
The mains connection (Fig. 3-4, 18, item G) is designed for a mains cable
which contains a European appliance connector on the device side.
A mains cable is supplied with the unit. If the plug is not compatible with your
wall socket, you have to get a suitable mains cable:
Three-conductor cable with protective ground
Conductor cross-section 3 ×1.5 mm2or larger
Fig. 3-5 Three-conductor cable with protective ground (example)
Mains power.
Improperly grounded devices can be extremely dangerous in the event of
a fault.
Use three-wire mains or extension cables with protective ground only. Plug
the mains cable into wall sockets with protective ground only.
No mains fuse.
The Multi-Channel Controller is not equipped with a mains fuse.
The wall socket must be protected with a fuse (max. 10 A).
1Connect the European appliance connector of the mains cord with the
mains connection of the unit
2Connect the plug of the mains cable with the wall socket
Note:
If the unit is installed in a switching cabinet, the mains power can be sup-
plied via a switchable central power distributor.
3.3.3 Ground
The ground screw (Fig. 3-4, 18, item I) can be used to connect the Multi-
Channel Controller with the protective ground of the pumping station.
1If required: Connect the protective ground of the pumping station with
the ground screw. Use a protective conductor.
