in Figure 1. That is, connect RxIN to SynchLink station transmitter, TxIN.
ATTENTION
!
Be certain that you secure the base block and 4-port
Splitter blocks together with DIN rail anchors. Failure to
do so may result in loss of communication and/or
damage to blocks.
Failure to use the DIN rail interlocks in hazardous
location installations could cause an explosion.
IMPORTANT
If you exceed the base block’s power limit, you may
cause damage to the base block.
ATTENTION
!
Do not look directly into the fiber ports or fiber cables. Light
levels may cause damage to eyesight.
