• Throughout the manual, this symbol warns of
consequences which may arise from inappropriate
use of the VARMECA 20, since electrical risks may lead
to material or physical damage as well as constituting a
fire hazard.
1 - General
Depending on their degree of protection, VARMECA 20
motors may contain moving parts, as well as hot surfaces,
during operation.
Unjustified removal of protection devices, incorrect use, faulty
installation or inappropriate operation could represent a
serious risk to personnel, animals and equipment.
For further information, consult the manual.
All work relating to transportation, installation, commissioning
and maintenance must be performed by experienced,
qualified personnel (see IEC 364 or CENELEC HD 384, or
DIN VDE 0100 and national specifications for installation and
accident prevention).
In these basic safety instructions, qualified personnel means
persons competent to install, mount, commission and operate
the product and possessing the relevant qualifications.
2 - Use
VARMECA 20 motors are components designed for
integration in installations or electrical machines.
When integrated in a machine, commissioning must not take
place until it has been verified that the machine conforms with
directive 89/392/EEC (Machinery Directive).
It is also necessary to comply with standard EN 60204, which
stipulates in particular that electrical actuators (which include
VARMECA 20) cannot be regarded as circuit-breaking
devices and certainly not as isolating switches.
Commissioning can take place only if the requirements of the
Electromagnetic Compatibility Directive (89/336/EEC,
modified by 92/31/EEC) are met.
VARMECA 20 motors meet the requirements of the Low
Voltage Directive 73/23/EEC, modified by 93/68/EEC. The
harmonised standards of the DIN VDE 0160 series in
connection with standard VDE 0660, part 500 and EN 60146/
VDE 0558 are also applicable.
The technical characteristics and instructions concerning the
connection conditions specified on the nameplate and in the
documentation provided must be observed without fail.
3 - Transportation, storage
All instructions concerning transportation, storage and correct
handling must be observed.
The climatic conditions specified in the technical manual must
be observed.
4 - Installation
The installation and cooling of equipment must comply with
the specifications in the manual supplied with the product.
VARMECA 20 motors must be protected against excessive
stress. In particular, there must be no damage to parts and/or
modification of the clearance between components during
transportation and handling. Avoid touching the electronic
components and contact parts.
VARMECA 20 motors contain parts which are sensitive to
electrostatic stress and may be easily damaged if handled
incorrectly. Electrical components must not be exposed to
mechanical damage or destruction (risks to health!).
5 - Electrical connection
When work is performed on VARMECA 20 motors which are
powered up, national accident prevention specifications must
be respected.
The electrical installation must comply with the relevant
specifications (for example conductor cross-sections,
protection via fused circuit-breaker, connection of protective
conductor). More detailed information is given in the manual.
Instructions for an installation which meets the requirements
for electromagnetic compatibility, such as screening,
earthing, presence of filters and correct insertion of cables
and conductors, are given in the documentation supplied with
the VARMECA 20. These instructions must be followed in all
cases, even if the VARMECA 20 carries the CE mark.
Adherence to the limits given in the EMC legislation is the
responsibility of the manufacturer of the installation or the
machine.
6 - Operation
Installations incorporating VARMECA 20 motors must be
fitted with additional protection and monitoring devices as laid
down in the current relevant safety regulations: law on
technical equipment, accident prevention regulations, etc.
Modifications to VARMECA 20 motors using control software
are permitted.
Active parts of the device and live power connections must
not be touched immediately after the VARMECA 20 is
powered down, as the capacitors may still be charged. In view
of this, the warnings fixed to VARMECA 20 motors must be
observed.
During operation, all protective covers must remain closed.
7 - Servicing and maintenance
Refer to the manufacturer’s documentation.
