Safety
6.1.1
Conditions for specified enclosure rating
To ensure compliance with the specified IP65 enclosure rating of the device during
operation, the following requirements must be met: If these requirements are not met,
the device does not fulfill any specified enclosure rating.
•
The device is mounted flush to the illumination using all 4 screws.
•
The storage media cover on the rear of the device is screwed tight to the device.
For the recommended tightening torque for the cover screws,
•
The cables plugged into the electrical M12 connections on the sides of the device
are screwed tight.
•
Any electrical M12 connections that are not being used must be sealed with
protective caps, depending on type. These plugs or caps must be screwed tight (as
delivered).
NOTICE
Only operate the device
without the storage media cover
for a short period while
inserting or removing the optional storage media (SSD drive, microSD memory card).
During this time, protect the device against moisture and dust.
6.1.2
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:
■
Metal housings are vulnerable to dangerous currents.
■
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 (e.g., ensuring low-impedance and current-carrying
equipotential bonding).
The cable shield of the electrical connections is connected to the metal housing of the
device via an M12 male connector.
If the peripheral devices have metal housings, and if the cable shields are also elec‐
trically connected with their housings, it is assumed that all devices involved in the
installation have the
same ground potential
.
This is achieved by complying with the following conditions:
