Light sensor input connections

If REF 610 is provided with the optional communication module with light sensor
inputs, the pre-manufactured lens-sensor fibres are connected to inputs X5.1 and
X5.2 (see 5.2.2.-1 and ). For further information on the arc protection, refer to
5.1.4.7. Arc protection.
REF 610 is provided with connection sockets X5.1 and X5.2 only if
the optional communication module with light sensor inputs has been
installed (refer to section Ordering information).

Serial communication connections

The optical front connection of the relay is used to connect the relay to the SPA bus
via the front communication cable, refer to Section 7. Ordering information. If a PC
compatible to the IrDA® Standard specifications is used, wireless communication is
possible as well. The maximum wireless operating distance depends on the
transceiver of the PC.
