NOTICE
Material damage
Risk of damage to the gear unit.
Care must be taken to ensure that no electric current can flow through gear units that are operated
together with electrical equipment that generate electric current or in which electriccurrent flows
(e.g. motors, generators). Electriccurrent flow can cause irreparable damage to rolling bearings and
teeth. Electriccurrent flow can be caused by e.g. short circuiting, voltage flashovers and conductive
dust layers.
Suitable measures may be:
– Use of insulators
– The gear unit must be properly earthed.
DANGER
Electrostatic discharge
Danger to life through ignition of any potentially explosive atmosphere through electrostatic discharge.
A potential equalisation in accordance with the applying regulations and/or directives must be carried
out.
On the gear units threaded holes are available for establishing an earth connection. This work must
always be done by specialist electricians.
NOTICE
Material damage
Risk of damage to the gear unit.
If any inexplicable changes are noticed during operation of the gear unit, such as an important increase
in temperature or unusual noises, the drive assembly must be stopped immediately.
DANGER
Danger to life through rotating and/or movable parts
Risk of being caught or drawn in by rotating and/or movable parts.
Rotating and/or movable parts must be fitted 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 prescriptions, notes and descriptions contained in these instructions are
incorporated in his own instructions.
DANGER
Risk of explosion
Danger to life through ignition of any potentially explosive atmosphere through the use of unsuitable
addon parts.
All addon parts must satisfy the requirements in Directive 94/9/EC.
Simple electrical means (such as monitoring devices, switches, Pt 100 measuring resistance) without
identification in accordance with Directive 94/9/EC must be connected intrinsically safely by suitable
isolation amplifiers.
