2. Assembly and operation
• The device can be assembled and operated only
by a person who possesses appropriate and valid
qualifications empowering them to use devices,
installations and networks at least in the field
of assembly of control-measurement devices,
as well as devices and installations of automatic
adjustment.
• When connecting the device to the wiring
system or introducing any modifications in the
connection system, the power supply should be
turned off. Power supply can be turned on after
connecting the wires and replacing the terminal
cover. During operation, employees authorized to
operate the device can have access to connection
terminals only, or else the power supply will be
turned off. Under no circumstances should the
insulation outside cover (front panel) of the elec
-
tronic and electric part be taken off the device.
2.1. Assembly
The device should be assembled in an upright po-
sition, in a place free from direct contact with rain
or sunlight. Application of an additional protec-
tion box is useful. In places where the tempera
-
ture often falls below -20°C it might be necessary
to provide heating.
The casing shall be fixed to a vertical base using
three screws or bolts of diameter 4 - 5mm. The
arrangement of fixing bolts is shown on the back
wall of the housing. Dependent on the conditions
you may use the catch included in the set. First,
fix it to the upper part of the casing with enclosed
screw. In this case the middle fixing screw must
be placed 40 mm higher than the value specified
on the casing.
The MR-Lift device has no anti-explosion
protection. Therefore, it can be installed only
outside explosion hazard areas.
2.2. Wiring
• The type of current and voltage must be identical
to data specified on the data plate of the device.
• Protection on behalf of the network must be
applied (max. 16A).
• Ground the pump / device according to regula-
tions.
• Let in endings of wires through relevant cable
glands in the lower part of the casing and connect
them in accordance with markings on the termi-
nal block.
• Unused cable glands must clog.
