Basic safety notes
14 05.00 | JGP-P | Assembly and Operating Manual | en | 1469637
2.12.1 Protection during handling and assembly
Incorrect handling and assembly
Incorrect handling and assembly may impair the product's safety
and cause serious injuries and considerable material damage.
lHave all work carried out by appropriately qualified
personnel.
lFor all work, secure the product against accidental operation.
lObserve the relevant accident prevention rules.
lUse suitable assembly and transport equipment and take
precautions to prevent jamming and crushing.
Incorrect lifting of loads
Falling loads may cause serious injuries and even death.
lStand clear of suspended loads and do not step into their
swiveling range.
lNever move loads without supervision.
lDo not leave suspended loads unattended.
2.12.2 Protection during commissioning and operation
Falling or violently ejected components
Falling and violently ejected components can cause serious
injuries and even death.
lTake appropriate protective measures to secure the danger
zone.
lNever step into the danger zone during operation.

lSwitch off the energy supply, ensure that no residual energy
remains and secure against inadvertent reactivation.
lNever rely solely on the response of the monitoring function
to avert danger. Until the installed monitors become effective,
it must be assumed that the drive movement is faulty, with its
action being dependent on the control unit and the current
operating condition of the drive. Perform maintenance work,
modifications, and attachments outside the danger zone
defined by the movement range.
lTo avoid accidents and/or material damage, human access to
the movement range of the machine must be restricted. Limit/
prevent accidental access for people in this area due through
technical safety measures. The protective cover and protective

Basic safety notes
05.00 | JGP-P | Assembly and Operating Manual | en | 1469637 15
fence must be rigid enough to withstand the maximum
possible movement energy. EMERGENCY STOP switches must be
easily and quickly accessible. Before starting up the machine
or automated system, check that the EMERGENCY STOP system
is working. Prevent operation of the machine if this protective
equipment does not function correctly.
2.12.4 Protection against electric shock
Possible electrostatic energy
Components or assembly groups may become electrostatically
charged. When the electrostatic charge is touched, the discharge
may trigger a shock reaction leading to injuries.
lThe operator must ensure that all components and assembly
groups are included in the local potential equalisation in
accordance with the applicable regulations.
lWhile paying attention to the actual conditions of the working
environment, the potential equalisation must be
implemented by a specialist electrician according to the
applicable regulations.
lThe effectiveness of the potential equalisation must be
verified by executing regular safety measurements.
