If you wish to know how two different types cable need to be routed, then proceed
as follows:
1. Look up cable type of first cable in column 1 (Cables for ...).
2. Look up cable type of second cable in the associated section of column 2 (and
cables for...).
3. In column 3 (routing ...): read off the routing guidelines to be observed.
– Mark all lines leading to the VAHLE POWERCOM
®
485 device.
– Provide suitable surge arrestors for all lines which may be exposed to lightning
strikes.
