Requirements for cables
a) Use exclusively shielded twisted-pair cables to connect the device.
b) Comply with the maximum permissible connection cables length.
Shielding and Equipotential Bonding
a) Apply the cable shield on a large contact area - ideally 360°. Use e. g. a shield terminal to
this purpose.
b) Pay attention to proper cable shield fastening.
c) Preferably connect the shield on both sides with low impedance to the protective earth (PE),
e.g.on the device and/or on the evaluation unit. In the event of potential differences, the
shield must only be applied on one side.
Operation Manual R60073.0009 - 03
Destruction of the device
Before connecting or disconnecting the signal cable, always
disconnect the power supply and secure it against switching on
again.
Improper installation
All lines and traveling cables must be double-insulated or
mechanically protected in compliance with EN 81-20 5.10.6. Pay
particular attention to short-circuit free routing.
General safety instructions
Make sure that the entire system is in a de-energized state during
electrical installation.
Other applicable manuals
Comply with the further relevant documentation such as data sheet,
operation manual and sensor manual, as well as with the
corresponding documents of the evaluation unit or of the elevator
control.
No open cable wires
Connect all required cable wires / connectors before commissioning.
Insulate individually all unused ends of the output signals to avoid
short-circuits.
• Electrostatic discharges at the contacts of the connector or at the
line ends could damage or destroy the device. Take appropriate
precautionary measures.
