10.5 Removing/Replacing Cables

Warning
Dangerous contact voltage - Prior to removing modules, the RSTi-EP
station must be completely de-energised (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.
Warning
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.
Caution
The components in the RSTi-EP series can be destroyed by electrostatic
discharge. Ensure that personnel and work equipment are adequately
grounded.
Caution
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,
Caution
always disconnect the 24 V supply (red pusher) first, before you disconect
the GND potential (blue pusher).
