4 Setup and connection
DANGER
Electric voltage
Risk of electric shock
a) Always disconnect the unit from the mains before per-
forming work.
b) Secure the equipment from accidental restarting.
c) The equipment may only be installed, maintained and
put into operation by instructed, competent personnel.
d) Always observe the applicable safety regulations for the
operating site.
4.1 Installation
The Multitronik mounts to a 35 mm (1.4") top-hat rail. This al-
lows it to easily be mounted in a central location without ad-
ditional mounting aids or installed in control cabinets.
The sensors connect via M12-plug-in connectors and a stand-
ard cable and make a modern control unit when combined
with the Multitronik.
DANGER
Electric voltage
Risk of electric shock
When connecting devices, please note the maximum voltages
and currents currents (see technical data) and use the correct
wire cross-sections and circuit breakers.
When selecting the connection lines, also note the maximum
operating temperatures of the devices.
Installation in special areas of application:
If the device will be installed outdoors or in wet areas, the
maximum operating voltage is max. 16 V DC effective or 35 V
DC.
4.2 Electrical connections
A cable connects the sensor to a jack at the bottom of the
device. This cable also supplies the input signal for the sensor.
Electricity is supplied via plug connectors. Please refer to the
appendix for installation dimensions, nominal voltage and
plug configuration.
The temperature switching outputs are PNP transistors (see il-
lustration):
