2. SAFETY REGULATIONS AND NOTES
Read the operating instructions carefully before working on the device
and every time before using it. Observe the following safety instructions
to prevent malfunctions or danger to persons. These operating
instructions are to be regarded as part of the device. Keep the operating
instructions close to the product so that users can access them at any
time. The device may only be sold or passed on together with the
operating instructions. The operating instructions must be accessible for
the operating and maintenance personnel. These operating instructions
may be duplicated and forwarded for information about potential dangers
and their prevention.
2.1 Levels of hazard warnings
These operating instructions use the following hazard levels to indicate
potentially hazardous situations and important safety regulations:
DANGER
Indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury. Compliance with
the measures is mandatory.
WARNING
Indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury. Exercise extreme
caution while working.
CAUTION
Indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury or damage of property.
NOTE
A potentially harmful situation can occur and, if not avoided, can
lead to property damage.
2.2 Staff qualification
Only electricians specialising in electrical explosion protection may
install the device, perform the test run and work on the electrical system.
The device may only be unpacked, operated, switched on or off, set,
used, run, disassembled and transported by suitable, qualified, trained
and authorised personnel.
2.3 Basic safety rules
A risk assessment in accordance with the Industrial Safety Regulation
(BetrSichV) must be performed before any use of the device. The safety
hazards associated with the device must be assessed again following
installation in the final product.
Observe the following when working on the unit:
;
The device is only to be used in proper technical working order for its
intended purpose, in a safe manner with attention to potential dangers
and in accordance with the operating instructions.
;
Any faults and defects which impair safety must be rectified
immediately.
;
Do not make any modifications, additions or conversions to the
device (such as modifying the guard grille or attaching other
equipment to the wall ring) without the approval of ebm-papst.
;
Modifications to the device result in loss of Ex approval. ebm-papst
Mulfingen GmbH & Co. KG does not accept any liability for resultant
damage.
2.4 Electrical voltage
;
Check the electrical equipment of the device at regular intervals; see
chapter 7.2 Safety test.
;
Replace loose connections and defective cables immediately.
DANGER
Live terminals and connections even with device
switched off
Electric shock, unintentional triggering of an ignition spark and
capacitive residual voltage can cause an ignition spark in the
event of a short circuit.
→ Before disconnecting the wires in the terminal box,
short-circuit the wires (L1, L2, L3) and PE outside the
explosion-hazard area, see chapter 5.8.2 Switching off
the device for maintenance work. #Wait five minutes
following all-pole disconnection of the voltage before
opening the terminal box.
CAUTION
In the event of failure, there is electric voltage at the
rotor and impeller
The rotor and impeller are base insulated.
→ Do not touch the rotor and impeller once they are installed.
CAUTION
If control voltage is applied or a speed setpoint is stored,
the motor will restart automatically, e.g. after power
failure.
Risk of injury
→ Keep out of the device danger zone.# When working on the
device, switch off the mains power and ensure that it cannot
be switched back on.
→ After working on the device, remove any tools used or
other objects from the device.
2.5 Safety and protective functions
DANGER
Protective device missing and protective device not
functioning
Without a protective device there is a risk of serious injury, for
instance if the hands reach or are sucked into the device during
operation.
→ Operate the device only with a fixed protective device and
guard grille.# The fixed protective device must be able to
withstand the kinetic energy of a fan blade that becomes
detached at maximum speed. There must not be any gaps
which it is possible to reach into with the fingers, for example.
→ The device is a built-in component. As the operator, you
are responsible for ensuring that the device is secured
adequately.
→ Stop the device immediately if a protective device is
found to be missing or ineffective.
