BEFORE INSTALLATION
IMPORTANT
It is recommended that the controller be kept at room
temperature for at least 24 hours before applying
power; this is to allow the evaporation of any
condensation resulting from low shipping / storage
temperatures.
US requirement, only: This device must be installed
in a UL-listed enclosure offering adequate space to
maintain the segregation of line voltage field wiring
and Class 2 field wiring.
CAUTION
To avoid electrical shock or equipment damage, you
must switch OFF the power supply before attaching /
removing connections to/from any terminals.
MOUNTING
Both models have the same dimensions (W x L x H =
110 x 180 x 60 mm) (see Fig. 2) and conform to IP20 (without
optional terminal protection cover) or IP30 (with optional
terminal protection cover; width is then 130 mm).

The Excel Smart I/O Compact can be mounted onto the DIN
rail simply by snapping it into place. It is dismounted by gently
pulling the stirrup located in the base of the housing (see Fig.

Wall/Ceiling Mounting/Dismounting
The Excel Smart I/O Compact can be mounted on walls or
ceilings in any desired orientation. In the case of ceiling
mounting, however, it should not be operated at ambient
temperatures exceeding 50 °C. The unit is mounted by
inserting 3.5-mm dowel screws through the corresponding
screwing noses.

Terminal Assignment
The Excel Smart I/O Compact features two rows of terminal
blocks located on one side for the connection of cables to the
inputs and relay outputs as well as for connecting the removable power supply terminal plug and removable
L
ONWORKS terminal plug.
NOTE: All relay and power supply terminal blocks are
orange-colored.
NOTE: According to VDE guidelines, it is not allowed to mix
low-voltage and high-voltage signals on the relays.
The Excel Smart I/O Compact is equipped with an adhesive
terminal assignment label on the top of the housing (see Fig.
1 on page 1).
