Warnings

The following safety measures must be observed during all phases of operation,
service, and repair of the device. Failure to comply with the safety precautions or
warnings in this document violates safety standards of design, manufacturing, and
intended use of the device and may affect the built-in protections.
DEV Systemtechnik shall not be liable for the failure of users to comply with these
requirements.
Disconnect the device from any external power line before opening of the housing.
In any case, the device is to be opened by trained service staff, only.
Environmental Conditions
The device is designed for indoor use and for an ambient temperature range.
Mechanical Integration
It is not permitted to fix the chassis on the rack mount flanges, only.
Balanced weight distribution of the chassis has to be ensured by placing it on a solid
surface or by using rack rails.
Sufficient airflow through the chassis must be ensured to achieve best cooling
results. Do not block or obstruct the airflow through the chassis at the front and at
the rear side, e.g. by placing large components close to the front side. It is
recommended to provide 1 RU space in the rack above and below the chassis to
ensure a good air circulation.
Heat Hazard
Top, bottom, and side surfaces may become hot when operating the device
continuously. To reduce the risk of injury from a hot surface, allow the surface to
cool before touching.
Grounding, AC Connection, Cables
To minimize shock hazard the device must be connected to an electrical ground via
a ground wire, please refer to chapter 4.2.2. For the AC connection, the device
must be connected to the AC power supply mains through two power cables with
three conductors and with the ground wire firmly connected to an electrical ground
(safety ground) at the power outlet. Any interruption of the protective ground con-
ductor will cause a potential shock hazard that might cause personal injury.
Risk of electrical shock and energy hazard:
Disconnecting a single power supply line only, does not interrupt the AC supply of
the device. To isolate the device completely, disconnect both power supply lines.
To power up the device connect the two power lines sequentially! The two power
lines must not be powered up simultaneously otherwise this may cause severe
damage of the device!
Do not connect the device to mains supply exceeding the specifications for input
voltage and frequency. The recommended AC cables to be applied are standard
high temperature power cables with type IEC 60320-C13 appliance plug appro-
priately rated to the conditions of the country where the device is operated.
