Warnings
The warnings in this chapter apply to the DEV 5072 Managed Power Supply
Chassis.
In combination with the DEV 5101 Online UPS for DEV 5072 there are additional
warnings stated in the DEV 5101 user manual!
The following safety measures must be observed during all phases of operation,
service, and repair of this equipment. Failure to comply with the safety precautions
or warnings in this document violates safety standards of design, manufacturing,
and intended use of this equipment 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 equipment is designed for indoor use and for an ambient temperature range of
-10…+50 °C (14…122 °F) at 100 % load. The maximum operational altitude is
3000 m (3280 yds.) above sea level.
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 DEV 5072 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 unit
continuously. To reduce the risk of injury from a hot surface, allow the surface
(particularly of a power supply module) to cool before touching.
Grounding, AC Connection, Cables
To minimize shock hazard the chassis must be connected to an electrical ground via
a ground wire, please refer to chapter 4.2.2. For the AC power connection, the
device must be connected to the AC power supply mains through a power cable
with three conductors per each installed power supply module and with the ground
wire firmly connected to an electrical ground (safety ground) at the power outlet.
