1.4 Transportation storage
All instructions concerning transportation, storage and correct handling must be
observed.
The climatic conditions specified in the technical manual must be observed.
1.5 Installation
The installation and cooling of equipment must comply with the specifications in the
documentation 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!).
1.6 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 documentation.
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.
1.7 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.
1.8 Servicing and maintenance
Refer to the manufacturer's documentation.
