Notes:
1: Combined circuits
2: Measured against the ground
3: Between signal lines
4: Measured against the ground and limited internally to 8.7V
5: Approved for Zones 2 and 22 hazardous areas with gas: IIC / IIB T4 and dust: T80°C;
only when USB connection is sealed and restricted breathing is maintained.
* : Ohmically limited
Cable:
10-wire standard cable with up to
0.5 mm² thick wires with 250 nF/km
max., 1000 µH/km and 34 ohms/km
min. has approx. 30 µH/ohm. Cable
length (flexible installation) is
limited to under 1000 m.
