Important: the overall length of the network must not exceed 500 m. Consequently if the terminal is also remote the length of the cable to the terminal is
included in the calculation of the total length.

cable represents a branch of the network, and therefore if this is greater than 5 m in length it can only be connected to the first or the last pCO in
the network.

The pCO

is also available with an optically-isolated serial pLAN. This simplifies installation, as the earthing requirements of the pCO
3
do not need to be observed. The
pCO

controllers can be connected to earth points with different voltages without the shield carrying current.
