2 Safety
2.1 General Safety Precautions
Follow the specifications contained in this description. Non-observance of the
instructions, operation outside of the following intended utilization, incorrect
installation/assembly or erroneous handling of the product can lead to severe
impairments with respect to the safety of personnel and systems/machines and result
in the revocation of warranty and liability claims.
Immediately after unpacking, check the scope of delivery for completeness and the
device for proper condition.
The device may not be commissioned or operated except by qualified personnel who
can be regarded as being "competent" in the sense of the EMV and Low Voltage
Directives.
Qualified personnel are individuals who are authorized to operate, ground and label
devices, systems and electrical circuits in accordance with safety technology
standards.
All relevant and generally recognized safety technology directives are to be complied
with while doing so.
If the voltage supply to the device is not provided by an on-board electrical system V
(24 V battery operation), then care must be taken to ensure that the external voltage is
generated and routed in accordance with the criteria for secure low voltage (SELV
[Separated Extra Low Voltage] pursuant to EN 60950), in view of the fact that this is
provided for supplying the connected control system, sensor system and actuating
elements without any other additional measures being implemented.
The wiring of all of the signals connected with the SELV circuit in the device must also
meet the SELV criteria (safe protective low voltage, securely disconnected galvanically
from other electrical circuits).
If the fed-in SELV voltage is grounded externally (PELV pursuant to EN 50178), then
responsibility for this and for compliance with any national installation regulations that
apply to the site of installation rest with the operator.
All of the statements made in this manual refer to devices which are not grounded in
terms of the SELV voltage.
Generally speaking, DIN VDE 0100 Part 410 is to be observed for the supply voltage.
Only the signals which are respectively specified in the Technical Data and/or on the
device label may be fed in at the connection terminals; only authorized HYDAC
ELECTRONIC GMBH accessory components may be connected to them.
In accordance with the following technical specifications, the device can be operated in
a wide range of ambient temperatures. Due to the additional self-heating of the device,
high perceptible contact temperatures may develop on the housing in hot
environments.
In the event of malfunction or uncertainty, please contact your HYDAC representative.
Unauthorized interventions in the device could result in grave impairments to the safety
of persons and systems. These are not permitted and lead to the exclusion of all
liability and warranty claims.
Troubleshooting and repairs may only be performed by our HYDAC SERVICE GMBH
Customer Service Department.
