(safety instructions and hazard warnings) are indicated by appropriate symbols (see chapter
). Follow these instructions in order to prevent accidents and danger to life
and limb, as well as damage to the E*LDS system.
Warning about dangerous electrical voltage! Danger of electric shock! Beware of external voltage at
the digital inputs and outputs! All device connections/male connectors may only be plugged in,
unplugged and/or wired when
.
no voltage is present
This operating manual is part of the device. It
be kept in the vicinity of the controller as well as for
must
future use so that it can be consulted when required. The operating manual must be available for the

Contact the supplier in the case of any malfunction.
Note that all supply lines from and to the device, particularly those of the CAN bus must be shielded or
installed with sufficiently large distance 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.
