• It is the responsibility of the
owner or the user to ensure that
the installation, operation and
maintenance of the drive and its options
comply with legislation relating to the
safety of equipment and personnel, and
with the current regulations of the
country of use.
• The DIGIDRIVE must be installed
in an environment free from conducting
dust, corrosive fumes, gases and fluids,
and condensation (for example class 2
according to UL 840 and IEC 664.1). The
drive must not be installed in hazardous
areas unless it is in an appropriate
enclosure. In this case the installation
must be approved.
• In atmospheres where
condensation may form, install a heating
system which operates when the drive is
not in use and is switched off when the
drive is in use. It is advisable to control
the heating system automatically.
• The DIGIDRIVE casing is not
fireproof. If necessary, use a flameproof
cabinet.
