Fig. 18 Control board and power board connections.
WARNING!
The relay terminals 21-33 are single
isolated. Do NOT mix SELV voltage
with e.g. 230 VAC on these
terminals.
A solution when dealing with mixed SELV/
system voltage signals is to install an
additional I/O board option ( see Chapter 12.3
page 155) and connect all SELV voltage signals
to the relay terminals of this option board while
connecting all 230VAC signals to the power
board relay terminals 21 - 33.
