6.1 Wiring instructions
NOTE
Pre-assembled cables can be found on the product page.
The call is made via the SICK Product ID: pid.sick.com/{P/N}/{S/N}
{P/N} corresponds to the part number of the product, see type label.
{S/N} corresponds to the serial number of the product, see type label (if indicated).
NOTICE
Faults during operation and defects in the device or the system
Incorrect wiring may result in operational faults and defects.
■
Follow the wiring notes precisely.
All circuits connected to the device must be configured as SELV or PELV circuits. SELV =
safety extra-low voltage, PELV = protective extra-low voltage.
Connect the connecting cables in a de-energized state. Do not switch on the supply
voltage until installation is complete and all connecting cables are connected to the
device and control.
Wire cross-sections in the supply cable from the customer’s power system must be
implemented in accordance with the applicable standards.
6.2 Prerequisites for safe operation of the device
WARNING
Risk of injury and damage caused by electrical current!
As a result of equipotential bonding currents between the device and other grounded
devices in the system, faulty grounding of the device can give rise to the following
dangers and faults:
•
Dangerous voltages are applied to the metal housings.
•
Devices will behave incorrectly or be destroyed.
•
Cable shielding will be damaged by overheating and cause cable fires.
Remedial measures
•
Only skilled electricians should be permitted to carry out work on the electrical
system.
•
If the cable insulation is damaged, disconnect the voltage supply immediately and
have the damage repaired.
•
Ensure that the ground potential is the same at all grounding points.
•
Where local conditions do not meet the requirements for a safe earthing method,
take appropriate measures. For example, ensure low-impedance and current-carry‐
ing equipotential bonding.
The device is connected to the peripheral devices (any local trigger sensor(s), system
controller) via shielded cables. The cable shield – for the data cable, for example –
rests against the metal housing of the device.
The device can be grounded through the cable shield or through a blind tapped hole in
the housing, for example.
