10.5 Removing/Replacing Cables
WARNING
Explosion Risk - Prior to starting work, ensure that there is not a potentially explosive
atmosphere.
DANGER
Dangerous contact voltage - Prior to removing modules, the RSTi-EP station must be
completely de-energized (supply of the field bus network adapter and all external feed-in).
Ensure that the place of installation (switch cabinet and so forth) has been disconnected
from the power supply.
CAUTION
•
In the event of the machine/system being put into a dangerous state as a result of
the removal of cables, a replacement can only be made once the machine/system is
disconnected from the power.
•
The components in the RSTi-EP series can be destroyed by electrostatic discharge.
Ensure that personnel and work equipment are adequately grounded.
•
The components in the RSTi-EP series can be destroyed by overcurrent. Potentials
may only be disconnected either simultaneously or in the correct order. At the
fieldbus network adapter as well as at power-feed modules, always disconnect the
24 V supply (red pusher) first, before you disconnect the GND potential (blue
pusher).
