4.2 Electrical Installation
4.2.1 General Information for the Connection
ATTENTION Destruction of the device
Before connecting or disconnecting the signal cable, always discon-
nect the power supply and secure it against switching on again.
NOTICE
General safety instructions
Make sure that the whole plant remains switched off during the elec-
trical installation.
• Make sure that the operating voltage is switched on or off simultan-
eously for the device and the downstream device.
NOTICE Other applicable manuals
Comply with the further relevant documentation such as data sheet,
operation manual and sensor manual, as well as with the corres-
ponding documents of the evaluation unit or of the elevator control.
NOTICE 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
cable ends could damage or destroy the device. Take appropriate
precautionary measures.
4.2.2 Information for EMC-Compliant Installation
Requirements for cables
• Use exclusively shielded twisted-pair cables to connect the device.
• Comply with the maximum permissible connection cables length.
Shielding and equipotential bonding
• Apply the cable shield on a large contact area - ideally 360°. Use e. g. a shield terminal to this
purpose.
• Pay attention to proper cable shield fastening.
• 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.
• If shielding is not possible, appropriate filtering measures must be taken.
• If the protective earth should be connected to the shield on one side only, it must be made
sure that no short-time overvoltages can appear on the signal and supply voltage lines.
