Safety during maintenance
•
Ensure that only qualified electricians perform all tasks on the electrical equipment.
•
Ensure that all work steps for maintenance are performed in the specified sequence.
•
Ensure that specified tightening torques are observed.
•
Ensure that all foreign objects are removed from the work area after the maintenance.
Injuries caused by the power supply and residual energy.
All power sources should be deactivated prior to carrying out maintenance work, and
secured against unintentional reactivation and marked with a sign indicating that mainte-
nance work is in progress. All moving parts should be stationary. Loads should be
secured against sagging or slipping. All components energized with electrical power
should be de-energized (Extinguished LED‘s on the servo amplifier do not mean that all
components have been completely de-energised). Check by measuring to ensure that
all components are de-energised. Work on electrical equipment may only commence if
the voltage is less than 42 VDC.
Injury of non-authorised personnel.
Maintenance work should only be realised by instructed personnel who have been autho-
rised to perform these tasks. The operating instructions laid down by the operator must
be rigidly adhered to.
Injuries resulting from maintenance work which has not been announced.
The working area should be secured over a wide area prior to realising maintenance work
and marked with warning signs. Operating personnel must be informed that maintenance
work is being carried out.
Injuries caused by the use of incorrect components or incorrect operating media.
Only spare parts which are specified in our spare parts lists should be used. Subsequent
modifications to the machine are not permitted. Only specified operating media should
be used. Self-securing screws and nuts should always be replaced. All specified screw
tightening torques should be strictly adhered to.
Injuries caused by the absence of safety equipment.
No safety equipment or safety components should be removed. Where dismantling of
individual safety equipment is unavoidable for maintenance purposes, the parts removed
should be refitted immediately after maintenance work is completed and tested to ensure
that the integrity of their safety functions is assured.
Risk of injuries through burning.
The temperature of the housing and the axles can reach up to 80 °C during operation.
Prior to carrying out any work on these components, the machine must first cool down
sufficiently, to avoid any risk of burning through contact. Burn injuries will arise from
contact with hot components.
