3.1
Safety information
Follow the instructions
The mechanical and electrical installation instructions must be adhered to. Any questions
or doubt should be referred to the supplier of the equipment. It is the responsibility of the
owner or user to ensure that the installation of the drive and any external option unit, and
WARNING
the way in which they are operated and maintained, comply with the requirements of the
Health and Safety at Work Act in the United Kingdom or applicable legislation and
regulations and codes of practice in the country in which the equipment is used.
Stored charge
The drive contains capacitors that remain charged to a potentially lethal voltage after the
AC supply has been disconnected. If the drive has been energized, the AC supply must
be isolated at least ten minutes before work may continue.
WARNING
Normally, the capacitors are discharged by an internal resistor. Under certain, unusual
fault conditions, it is possible that the capacitors may fail to discharge, or be prevented
from being discharged by a voltage applied to the output terminals. If the drive has failed
in a manner that causes the display to go blank immediately, it is possible the capacitors
will not be discharged. In this case, consult Control Techniques or their authorized
distributor.
Competence of the installer
The drive must be installed by professional assemblers who are familiar with the
requirements for safety and EMC. The assembler is responsible for ensuring that the end
