NOTICE
Faults due to incorrect wiring.
Incorrect wiring may result in operational faults.
■
Follow the wiring notes precisely.
We recommend using shielded cables.
Connect the connecting cables in a de-energized state. Switch on the supply voltage
only after complete installation/connection of all connecting cables to the device and
control system.
6.2 Security
WARNING
Risk of injury and damage caused by electrical current!
As a result of equipotential bonding currents between the device and other grounded
devices in the system, faulty grounding of the device can give rise to the following dan‐
gers and faults:
■
Dangerous voltages are applied to the metal housings.
■
Devices will behave incorrectly or be destroyed.
■
Cable shielding will be damaged by overheating and cause cable fires.
Remedial measures
■
Only skilled electricians should be permitted to carry out work on the electrical sys‐
tem.
■
If the cable insulation is damaged, disconnect the voltage supply immediately and
have the damage repaired.
■
Ensure that the ground potential is the same at all grounding points.
■
Where local conditions do not meet the requirements for a safe earthing method,
take appropriate measures (e.g., ensuring low-impedance and current-carrying
equipotential bonding).
Only skilled electricians with appropriate training and qualifications are permitted to
perform electrical installation. Observe the following safety measures:
•
Standard safety requirements must be met when working in electrical systems.
•
Only connect and disconnect electrical connections when there is no power to the
system. Otherwise, the devices may be damaged.
•
Use only shielded cables. The shield has to be terminated at both ends of the
cable.
•
Ensure that loose cable ends are isolated.
•
Connect unused pins to GND.
•
Wire cross sections of the supply cable from the customer's power system should
be designed and protected in accordance with the applicable standards.
