2 Safety Information
This operating manual is part of the device. It must be kept in the vicinity of the controller as well as for future
use so that it can be consulted when required. The operating manual must be available to the operating and
maintenance personnel at all times in order to avoid operating errors. The safety regulations, instructions and
information must be strictly observed and complied with. During repairs on the entire E*LDS system, the
accident prevention regulations and general safety regulations must be strictly complied with. Important
information (safety instructions and hazard warnings) are indicated by appropriate symbols, see chapter
Conventions. Follow these instructions in order to prevent accidents and danger to life and limb, as well as
damage to the E*LDS system!
Always observe the following information:

For safety reasons, the equipment must not be used for any applications other than described in the
operating manual and only for the intended use.
Before using the device, check whether it is suitable for your application with regard to its limit values.
The equipment must be installed in an electrically shielded area within the switch cabinet.
The use of wire end ferrules with plastic collars on the COMBICON mating connectors is mandatory as
splice protection!
Before connecting the device, it must be checked whether the power supply is suitable for the device.
Coded connectors must be used, as there is a possibility of plugging in non-coded connectors in such a
way that there is a danger to life and limb!
Specified ambient conditions (e.g. humidity and temperature limits, see chapter Technical Data) must be
observed and complied with at all times to prevent malfunction.
Before switching on the device, check the correct wiring of the connections.
The device must never be operated without its housing. If the intended use requires opening the housing,
the control unit must be disconnected from the power supply before opening the housing.
Note the maximum load of the relay contacts, see chapter Technical Data.
Note that all supply lines from and to the device, particularly those of the CAN bus and Modbus, must be
shielded or installed sufficiently far away from live cables. This prevents faulty measurements and protects
the device against electrical interference via the analogue inputs. Connection in parallel of RC elements is
recommended for applications with critical environment.
Contact the supplier in the case of any malfunction.
DANGER
Warning of dangerous electrical voltage! Danger of electric shock!
Beware of external voltage at the digital inputs and outputs (relay/SSR)! Connections/plug connectors
of the device may only be plugged in, removed and/or wired when no voltage is present.
