3. Safety instructions
9
Selection and training of personnel;
basic responsibilities
Work on/with the control must be carried out by reliable
personnel only. Statutory minimum age limits must be
observed.
Employ only trained or instructed personnel and clearly
set out individual responsibilities for operation, setup,
maintenance and repair.
Ensure that only authorized personnel work on or with
the machine.
Define the machine operator's responsibilities, giving
the operator the authority to refuse instructions by third
persons that are contrary to safety regulations.
Do not allow persons to be trained or instructed or
persons taking part in a general training course to work
on or with the control without being continuously
supervised by an experienced person.
Work on the electrical equipment of the control must be
carried out only by a skilled electrician in accordance
with electrical engineering rules and regulations.
3.3 Changes and modifications
Do not make any changes, modifications or
attachments to the control which could affect safety
without the supplier's prior permission.
Unauthorized changes to the unit are not permitted for
safety reasons.
Original parts were designed specifically for this unit.
We wish to point out that we have not approved and will
not approve parts and special accessories which have
not been supplied by us. The installation and/or use of
such products can therefore affect active and/or passive
safety.
The manufacturer cannot be held liable for damage
resulting from the use of non-original parts or special
accessories.
3.4 Installation and normal operation
Installation
In addition to general operating requirements laid down
by local authorities, the following specific instructions
must be observed.
For the lifting of a control cabinet, suitable lifting gear
must be used which meets local safety regulations. All
loose or slewable parts must be safely fixed before the
unit can be lifted. It is strictly prohibited for personnel to
remain within the danger zone of a lifted load.
The correct method of lifting (according to the operating
instructions of the load suspension device) must be
ensured.
If a remote control is used, the system must carry a
clearly visible notice as follows: Attention: This system
is operated by remote control and can start up without
prior warning!
As an additional safety measure, persons who start
remotely controlled systems must take adequate safety
precautions to ensure that nobody is checking or
working on the system. A label with a corresponding
warning notice must be attached to the remote control
equipment.
If a system comprises several compressors, hand-
operated isolator valves must be installed in order to be
able to shut off each machine individually. When
working with pressure systems, do not rely on the
effectiveness of check valves alone to isolate these
systems.
Safety equipment, protective covers or insulation must
not be removed or modified. Any pressure vessel which
is located outside the system, the permissible operating
pressure of which is higher than atmospheric pressure
and which is fitted with two or more pressure supply
lines, must be provided with additional safety equipment
that will automatically prevent the pressure from
exceeding the permissible operating pressure by more
than 10%.
Electrical connections must comply with local
regulations. Power units must be connected to earth
and protected from short-circuits by means of fuses.
Normal operation
Take all necessary precautions to ensure that the
system is used only when in a safe and reliable state.
Operate the system only when all protective equipment,
emergency shut-off equipment, soundproofing elements
and extraction devices are in place and in full working
order.
