▸
The device is conceived according to DIN EN 61800-1/ DIN EN 50178for the dirt
level 2. That means: Ensure to avoid conductive impurities during the operation.
▸
Devices with air cooling only can be loaded to their maximum up to a height of
1000 m above MSL (3281 ft above MSL). For an operation in areas higher than
1000 m (3281 ft) above MSL the capacity must be reduced by 1.5 % per 100 m
(328 ft).
The maximum site altitude is 2000 m (6562 ft) above MSL for IT mains and 3000 m
(9843 ft) above MSL for symmetrically grounded TN and TT mains..
▸
The device must be protected against harmful gas, oil vapor and salty air at the
place of installation.
▸
The ambient air must not contain aggressive, grinding, electrically conductive or
flammable substances as well as any amount of dust.
▸
The maximum relative humidity during operation is 85 % (no condensation).
▸
The allowed ambient temperature for the operation is +5 °C to +40 °C (+41 °F to
+104 °F). Extreme and sudden changes of the temperature should be prevented.
– Ensure power derating for devices used in ambient temperatures over +40 °C
(+104 °F) (see technical data). The following applies: -1.5 % per 1 °C. Note:
F=C×9/5+32; C=(F-32)×5/9
– Devices with polyester films: The polyester films must not be exposed to direct
sunlight for extended periods of time. In conditions of high humidity (>80 %) the
ambient temperature must not exceed +40 °C (+104 °F). The polyester films
must not come in contact with benzyl alcohol or methylene chloride.
▸
Make sure that the aeration elements are free and open, so that the air circulation
is not restricted.
3.7 Electrical Connection
DANGER
Risk of serious injuries due to touch voltages
After electric devices have been switched off touch voltages may occur de-
pending on the device up to 4 minutes. Longer construction-related dis-
charge times are possible. Refer to the product documentation of your de-
vice.
→ All work at and within the units must only be carried out, when the
units are turned off, the mains supply is cut and the DC bus is com-
pletely discharged.
→ Never touch energized parts after a device has been switched. off.
→ Consider the VDE regulations and the applicable accident prevention
regulations (e.g. VBG 1 and VBG 4).
DANGER
Risk of serious injuries due to improper connection to earth
Incorrect or insufficient connection of the system to earth may cause dan-
gerous currents.
→ Connection to earth must be realized according to the instructions in
the product documentation of your device.
The electrical installation must be carried out according to the relevant electrical codes
(e.g. appropriate wire gauges, fuse protection and connections of ground conductors
must be considered).
