4 - Installation
The installation and cooling of equipment
must comply with the specifications in the
manual supplied with the product.
The variable speed drives must be
protected against any 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.
The variable speed drives contain parts
which are sensitive to electrostatic stresses
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 variable speed
drives which are powered up, the national
accident prevention regulations 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 variable
speed drives.
These instructions must be followed in all
cases, even if the variable speed drive
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 in which variable speed drives
are to be integrated must be fitted with
additional protection and monitoring
devices as laid down in the current relevant
safety regulations, such as the law on
technical equipment, accident prevention
regulations, etc. Modifications to the
variable speed drives using control
software are permitted.
Active parts of the device and the live
power connections must not be touched
immediately after the variable speed drive
is powered down, as the capacitors may
still be charged. In view of this, the
warnings fixed to the variable speed drives
must be observed.
During operation, all doors and protective
covers must be kept closed.
7 - Servicing and maintenance
Refer to the manufacturer’s documentation.
This manual is to be given to the end
user.
