Notes on the 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.
■
The electrical installation must only be performed by electrically qualified person‐
nel.
■
Standard safety requirements must be observed when working on electrical
systems!
■
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 an extension cable with an open end, make sure that bare wire ends
are not touching (risk of short-circuit when the supply voltage is switched on).
Wires must be properly 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 done in Ger‐
many, observe the following standards: DIN VDE 0100 (Part 430) and DIN VDE
0298 (Part 4) 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 at the start of the supply circuit. Protect
devices without heating with a maximum of 2 A, heatable devices with a maximum
of 3 A .
NOTE
Layout of data cables
■
Use screened data cables with twisted-pair wires.
■
Implement the screening design correctly and completely.
■
To avoid interference, always use EMC-compliant cables and layouts. This applies,
for example, to cables for switched-mode power supplies, motors, clocked drives,
and contactors.
■
Do not lay cables over long distances in parallel with power supply cables and
motor cables in cable channels.
