4.1 Electrical Installation
4.1.1 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
Traction relief
Always mount all cables with traction relief.
NOTICE
Interference susceptibility
Proceed as follows:
• Connect the shield to the device housing.
• Comply with the maximum cable length for stub lines and for the
total length of the bus network.
• Check the maximum supply voltage on the device.
ATTENTION
Wear of the memory module
Avoid too frequent writing of the EEPROM. It is used e.g. when set-
ting a preset value. The memory module is designed for approxim-
ately 500,000 write cycles. If the maximum number of write cycles is
exceeded, single memory areas may be damaged and errors may
occur.
4.1.2 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.
