NOTICE
Property damage
Damage to the gear unit is possible.
For gear units, which are operated together with electrical machines that generate power or that are
supplied with power (e. g. motors, generators, etc.), it must be ensured that
no
current can flow through
the gear unit. The flow of current can lead to irreparable damages on rolling bearings and gear teeth.
Flow of current can arise, e. g. through short circuits, flash arcs, conductive dust layers, etc.
Suitable measures may be:
– Use of isolators
– Earth the gear unit professionally
DANGER
Electrostatic discharge
Danger to life from ignition of present explosive atmosphere by electrostatic discharge.
A potential equalisation in accordance with the applying regulations and directives must be carried out.
Threaded holes for an earth connection are provided on the gear units or on the output flange. This work
must always be done by
trained electricians
.
NOTICE
Property damage
Damage to the gear unit is possible.
Immediately stop the gear unit by turning off the drive unit when inexplicable changes are noticed
during the operation, such as a significantly increased operating temperature or changed sounds of
the gear unit.
DANGER
Danger to life from rotating and/or moving parts
Risk of being gripped or drawn in by rotating and/or moving parts.
Rotating and/or movable drive parts must be provided with suitable safeguards to prevent contact.
Note
When the gear unit is incorporated in plant or machinery, the manufacturer of such plant or machinery
must ensure that the requirements, notes and descriptions contained in these instructions are
incorporated in its own instructions.
DANGER
Explosion hazard
Danger to life from ignition of present explosive atmosphere by use of unsuitable add-on parts.
All add-on parts must satisfy the requirements in Directive 2014/34/EU.
Simple electrical means (such as monitoring devices, switches, Pt 100 measuring resistance) without
identification in accordance with Directive 2014/34/EU must be connected intrinsically safe by means
of suitable isolation amplifiers.
