Operating instructions G3G250-MW50-01
Translation of the original operating instructions
3.7 Electromagnetic compatibility
If several devices are switched in parallel on the mains side so
that the line current of the arrangement is in the range of 16 - 75
A, then this arrangement conforms to IEC 61000-3-12 provided
that the short-circuit power S
sc at the connection point of the
customer system to the public power system is greater than or
equal to 120 times the rated output of the arrangement.
It is the responsibility of the installation engineer or operator/
owner of the device to ensure, if necessary after consultation
with the network operator, that this device is only connected to
a connection point with a S
sc value that is greater than or equal
to 120 times the rated output of the arrangement.
4. CONNECTION AND START-UP
4.1 Connecting the mechanical system
DANGER
Gas leaking from improperly sealed housing
Risk of fatal injury
→ Prior to commissioning, check that the housing of the gas
blower is pressure-tight.
When doing so, close the intake and exhaust opening and
the shaft opening.
→ In addition, check that rotating parts do not scrape against
stationary parts.
DANGER
Leaks may occur.
As a result of design necessities, the gas blower is not tightly
sealed, e.g. at the shaft opening. This may cause leaks during
operation. Deflagrations may also cause long-term damage or
deformation of the housing, which can result in leaks. An air/
gas mixture may accumulate outside of the gas blower. The
blower may explode. You could be severely injured.
→ Check which hazards arise from installing, operating,
servicing or disposing of the gas blower in conjunction with
your device.
Prevent these hazards.
Carry out all appropriate measures to this purpose.
CAUTION
Cutting and crushing hazard when removing the blower
from the packaging
→ Carefully remove the blower from its packaging, only
touching the housing. Make sure to avoid any shock.
→ Wear safety shoes and cut-resistant safety gloves.
CAUTION
Heavy load when taking out the device
Bodily harm, e.g. back injuries, are possible.
→ Two people should remove the device out of its packaging
together.
; Check the device for transport damage. Damaged devices must no
longer be installed.
; Install the undamaged device according to your application.
4.2 Connecting the electrical system
DANGER
Electric voltage on the device
Electric shock
→ Always install a protective earth first.
→ Check the protective earth.
DANGER
Incorrect insulation
Risk of fatal injury from electric shock
→ Use only cables that meet the specified installation
requirements for voltage, current, insulation material, load etc.
→ Route cables such that they cannot be touched by any
rotating parts.
