Vibrations beyond these limits are always considered as abnormal mechanical condi‐
tion. This requires mechanical decoupling of the machine and drive.
For detailed information on the vibration limits refer to the technical data of the device
or contact SIEB & MEYER.
Operating conditions:
The following requirements are to be considered for the installation and the operation
of the device. Noncompliance with theses requirements is regarded as abnormal oper‐
ating condition:
▶ The device is conceived according to DIN EN 61800-1 / DIN EN 50178 for the dirt
level 2.
▶ The units can be loaded to their maximum up to a height of 1000 m above MSL
(3281 ft above MSL).
▶ 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 admissible ambient temperature during operation is +5 °C to +40 °C (+41 °F
to +104 °F). Extreme and sudden changes of the temperature should be
prevented.
▶ Make sure that the aeration elements are free and open, so that the air circulation
is not restricted.
2.5 Electrical Connection
DANGER
Risk of serious injuries due to touch voltages
After electric devices have been switched off touch voltages may occur depending
on the device up to 4 minutes. Longer construction-related discharge times are
possible. Refer to the product documentation of your device.
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 completely discharged.
Never touch energized parts after a device has been switched. off.
Consider the applicable VDE regulations and 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 ground may cause dangerous
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).
