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.

The Excel Smart I/O Compact is equipped with:

•three relays,

•three digital inputs, and

•three analog inputs, which may be used as slow digital inputs or as NTC20k temperature sensor inputs.

See also Table 1 on page 2 for a complete overview of terminals and their functions.

The two models of the Excel Smart I/O differ only in their power supply:

•XFCL2A1: 230 Vac power supply

•XFCL3A1: 24 Vac power supply

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. 3). When mounted on a DIN rail, the unit must be secured in place with a stopper to prevent sliding.

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.

When equipped with the optional terminal protection cover (see section "Terminal Protection Cover" on page 6), the Excel Smart I/O Compact conforms to IP30.

After mounting the Excel Smart I/O Compact onto the wall or ceiling, 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 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 LONWORKS 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).
