explosion group IIC, it must be protected from static charging by a steel
protective conduit or steel tube.

Recommended accessories for trouble-free operation:
1. Install the driver ds82x.od130 in a housing/control cabinet. For this we recommend
AC-2108 for up to 3 drivers and AC-2109 for up to 6 drivers.
2. Use shielded signal wiring (preferably AC-1114) between the driver and connected elec-
tronics. The connection cable has to be heat-resistant at least +85 °C.

conduit.
