The encoder can optionally be powered by the 5-V-power-supply which is integrated in the
FM502-CMS.
Encoder/counter signals must be laid in shielded cables. The cable shield must be earthed at
both sides of the cable. In order to avoid unacceptable potential differences between different
parts of the installation, low-resistance equipotential bonding conductors must be laid. Only for
applications with low disturbance and/or cables length < 30 m the shield might be omitted.
The 5 V output provides a current of 100 mA max.
NOTICE!
Risk of damaging the FM502-CMS!
The 5 V output has no protection against reverse polarity.
