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 table 4.2.2-1 and Fig. 4.2.1.-1). For further information on the arc
protection, refer to section Arc protection.
Note!
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 1MRS050698. 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.
Rear communication of REF 610 is optional and the physical connection varies with
the communication option.
