1. Safety instructions

Follow the operating instructions. Non-observance of the instructions, operation
which is not in accordance with use as prescribed below, wrong installation or
handling can affect the safety of people and the plant.
The installation and connection must comply with the applicable national and in-
ternational standards. Responsibility lies with the person installing the unit.
The unit must be installed, connected and put into operation by a qualified electri-
cian as
• during the installation dangerous contact voltage occurs and
• the safe function of the unit and the plant is only guaranteed when installation
is correctly carried out.
Disconnect the unit externally before handling it. Also disconnect any indepen-
dently supplied relay load circuits.
Be careful when handling the connected unit. Due to the protection rating IP 20
this is only allowed by qualified staff.
The design of the unit corresponds to the protection class II except for the terminal
blocks. Protection against accidental contact (safety from finger-touch to IP20) for
qualified staff is only guaranteed if the terminal screw has been completely
screwed in. For the correct operation the unit must be mounted in a housing (pro-
tection rating IP40 or higher) which can only be opened using a tool or in a closed
control cabinet.
If the unit has an external 24 V DC supply, this voltage must be generated and
supplied externally according to the requirements for safe extra-low voltage (SELV)
since without further measures this voltage is supplied near the operating ele-
ments and at the terminals for the supply of connected pulse pick-ups.
The wiring of all signals concerning the SELV circuit of the unit must also meet the
SELV criteria (safe extra-low voltage, safe electrical separation from other circuits).
If the externally supplied or internally generated SELV voltage is externally ground-
ed, the responsibility lies with the user in accordance with the applicable national
installation regulations. All statements in the operating instructions refer to the
unit which is not grounded with respect to the SELV voltage.
It is not allowed to supply external voltage to the terminals for the pulse pick-up
supply and the analogue output.
The consumption of current which exceeds the value given in the technical data is
not allowed.
An external main switch must be installed for the unit which can switch off the
unit and all related circuits. This main switch must be clearly assigned to the unit.
