6.1 Wiring instructions
NOTE
Pre-assembled cables can be found online at:

NOTICE
Faults during operation and device or system defects!
Incorrect wiring may result in operational faults and defects.
■
Follow the wiring notes precisely.
WARNING
Danger of electrical shock if a non-certified power supply unit is used!
Only use a power supply unit which complies with the safety extra low voltage (SELV)
and limited power source (LPS) requirements.
To ensure electrical safety, we recommend using a shielded connecting cable
(
www.sick.com/midiCam2 under accessories) or earthing the camera housing so that
it is connected to ground due to the installation set-up.
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 dan‐
gers 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 sys‐
tem.
■
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 (e.g., ensuring low-impedance and current-carrying
equipotential bonding).
The device is connected to the peripheral devices (voltage supply, any local trigger sen‐
sor(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.
If the peripheral devices have metal housings and the cable shields are also in contact
with their housings, it is assumed that all devices involved in the installation have the
same ground potential .
