Important notes
WARNING
Risk of injury and damage caused by electrical current!
Due to equipotential bonding currents, incorrect earthing can lead to the following
dangers and faults: Voltage is applied to the metal housing, cable fires due to cable
shields heating up, the product and other devices become damaged.
■
Generate the same ground potential at all grounding points.
■
Ground the equipotential bonding via the functional ground connection with a low
impedance (use standard cable lug with M4 hole).
NOTICE
Device damage due to improper supply voltage!
■
Only operate the device with the specified supply voltage.
■
The voltage supply and all connected signals must meet the requirements for
extra-low voltages with safe separation (SELV) as specified in EN 61010. The
external voltage supply of the device must bridge a short-term power interruption
of 20 ms in order to meet the requirements of EN 60204-1.
■
Only devices that are also supplied with safety extra-low voltage must be con‐
nected.
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.
6.2
Preparing the electrical installation
To carry out the electrical installation, you will need:
•
Connection cables for the peripheral devices, including the corresponding data
sheets
•
Fan connection (
see "Preparatory commissioning", page 29
•
Voltage supply cable
•
If customers assemble the cables: crimping tool, ferrules, soldering iron, and other
installation material
6.3
Preparing the cables
For a list of cables suitable for use with the device, see the document “SIMxxxx_Cable-
Overview” available from:
.
Customer assembly of the cables is only necessary in special cases. Ensure a sufficient
length of cable is provided, e.g., for strain-relief clamps.
