5 Installation
u
Mount the unit in a control cabinet with a protection rating of at least IP 54 to ensure protection
against accidental contact with dangerous contact voltages and against atmospheric influence.
The control cabinet should be installed in accordance with local and national rules and regulations.
u
Mount the unit vertically on a DIN rail.
u
Leave enough space between the unit and neighbouring heat sources and the top or bottom of the
control cabinet to enable air circulation and to avoid excessive heating.
u
Prevent penetration of conductive or other dirt during installation and wiring.
When preparing for cable installation, the local conditions and the corresponding mounting regulations
are very important. Cables can be installed, for example, in cable ducts or on cable bridges.
A minimum distance between the cabling and possible sources of interference (e.g. machines, welding
equipment, power lines) is defined in the applicable regulations and standards. During system
planning and installation, these regulations and standards must be taken into account and observed.
Protect the bus cables from sources of electric/magnetic interference and mechanical strain.
Observe the guidelines regarding "electromagnetic compatibility" (EMC) to keep mechanical risks and
interference to a minimum.
5.1 Sources of interference
u
Signal cables and power supply lines should not be installed in parallel.
u
If necessary, metal isolating segments should be placed between the power supply lines and signal
cables.
u
During installation, all connector locking mechanisms (screws, coupling nuts) must be firmly
tightened in order to ensure the best possible contact between shielding and ground. Before initial
start-up, the ground or shielding connection of cables must be checked for low-resistance
continuity.
5.2 Cable routing
Network/bus cables
u
Install network/bus cables in separate cable ducts or separate cable bundles.
u
Where possible, do not install network/bus cables parallel to power supply lines.
u
Install network/bus cables at least 10 cm away from power lines.
5.3 Installation instructions
Electrostatic discharge
The device contains components that can be damaged or destroyed by electrostatic discharge.
u
When handling the device, observe the necessary safety precautions against electrostatic
discharge (ESD) according to EN 61340-5-1 and IEC 61340-5-1.
Only operate the device when mounted on a grounded DIN rail in order to dissipate electrostatic
charges.
