ATTENTION!
The mains voltage (supply voltage) must
match the specifications on the rating
plate of the Lubrication Monitor Controller.
Check the fuse protection of the electrical
circuit. Use only fuses with the prescribed
amperage,
4.4 Electrical connection
4.4.1 General
The controller unit is supplied with
110 to 240 V AC voltage or optionally with
24 V DC voltage.
In both designs, the cables are introduced
through a cable fitting with a clamping range
of Ø 4.5 mm to Ø 10 mm and terminal blocks
with tension springs (maximum conductor
cross-section 2.5 mm, conductor stripping
length 15 mm).
Consult Chapter 3, Technical Data, for the
electrical characteristics of the controller unit.
The connections on the controller
unit are established according to the custom-
er-specific design of the lubrication system/
main lines. The system manufacturer is thus
responsible for correct connection to the con-
troller unit.
WARNING
Electric shock
De-energize the control unit prior to
beginning work.
Only qualified personnel authorized
by the operator may perform work
on controller unit.
The electrical operating conditions
and local regulations (e.g., DIN, VDE)
must be observed.
ATTENTION!
The Lubrication Monitor Controller
contains electronic components that
can be destroyed by accidental elec-
trostatic charge or discharge (ESD).
To prevent possible damage due to
ESD, hands and any tools must be
discharged on a bare grounded posi-
tion on the installation site prior to
performing any work on the opened
control unit. Conductors or compo-
nents within the device must not be
touched under any circumstances.

• Loosen the cable fitting.
• Draw the connection cable provided by cus-
tomer into the cable fitting.
• Connect the connection cable (provided by
customer) according to the wiring diagram
(see Figs. 6 to 12).
• Tighten the cable fitting.

see Figures 4 and 5, item 1, and Figure 3
The wires on the terminal strips for:
o power connection (item 1)
o digital outputs (item 2)
o analog outputs (item 3)
o relay (item 4)
are connected via a tension spring mecha-
nism. The following procedure should be used
for this
• Press the tension spring back using the flat
tip screwdriver.
• Insert flexible cable leads into the terminals.
• Release pressure on the tension spring.
• Check the wiring for tight fit.

ATTENTION!
You can run each terminal block (4.1 or 4.2) only
with one operating voltage (24VDC or
100 to 240 VAC). Do not mix 2 different voltages
together on 1 terminal block.
ATTENTION!
An appropriate switch or circuit-breaker
(min. 10A) who protect all pole must be
included in the building installation and shall
be in close proximity to the equipment within
easy reach of the OPERATOR.
The disconnecting device shall be marked as
the device for the equipment.
