After mounting the unit onto the wall, provide for cable access
by snipping out the terminal protection cover's cut-out tabs
and snap it (by hand) into place on the housing. To remove
the cover, place a screwdriver in the leverage slot and pry it
loose.
Terminal Assignment
The unit features two rows of terminal blocks located on one
side for the connection of cables to the relays, inputs, and
outputs as well as for connecting the removable power supply
terminal plug and removable L
ONWORKS terminal plug.
NOTE: All high-voltage terminal blocks are orange-colored.
Depending on the given hardware model, the units have
different power supplies and are equipped with different
numbers of triac outputs, relay outputs, etc. See Table 2 on
page 3.
Every unit is therefore equipped with a terminal assignment
label on the top of the housing (see Fig. 1 on page 1). Unused
terminals are indicated by dotted lines.
NOTE: According to VDE guidelines, it is not allowed to mix
low-voltage and high-voltage signals on the relays.
