6.1 Safety
6.1.1 Notes on electrical installation
NOTICE
Equipment damage due to incorrect supply voltage!
An incorrect supply voltage may result in damage to the equipment.
■
Only operate the device using a protected low voltage and safe electrical insulation
as per protection class III.
NOTICE
Equipment damage or unpredictable operation due to working with live parts.
Working with live parts may result in unpredictable operation.
■
Only carry out wiring work when the power is off.
■
Only connect and disconnect electrical connections when the power is off.
■
Electrical installation must only be performed by electrically qualified personnel.
■
Standard safety requirements must be observed when working on electrical sys‐
tems.
■
Only switch on the supply voltage for the device when the connection tasks have
been completed and the wiring has been thoroughly checked.
■
When using extension cables with open ends, ensure that bare wire ends do not
come into contact with each other (risk of short-circuit when supply voltage is
switched on!). Wires must be appropriately insulated from each other.
■
Wire cross-sections in the supply cable from the user’s power system must be
selected in accordance with the applicable standards. When this is being done in
Germany, observe the following standards: DIN VDE 0100 (Part 430) and DIN VDE
0298 (Part 4) and/or DIN VDE 0891 (Part 1).
■
Circuits connected to the device must be designed as SELV circuits (SELV = Safety
Extra Low Voltage).
■
Protect the device with a separate fuse of max. 2 A at the start of the supply cir‐
cuit.
NOTE
Layout of data cables
■
Use screened data cables with twisted-pair wires.
■
Implement the screening design correctly and completely.
■
To avoid interference, e.g. from switching power supplies, motors, clocked drives,
and contactors, always use cables and layouts that are suitable for EMC.
■
Do not lay cables over long distances in parallel with power supply cables and
motor cables in cable channels.
The specified enclosure rating IP69K is achieved for the device only under the following
conditions:
■
The protective housing is assembled as described in these instructions.
■
The Ethernet connection of the device is used: see "Assembly with use of the
Ethernet connection", page 20
■
The Ethernet connection of the device is not used: see "Assembly without use
of the Ethernet connection", page 22
■
Use of the specified cables, see "Cables", page 34
