The hardware variant W7704F1003 is cost-optimized for light control and does not support hardwired wall modules.

BEFORE INSTALLATION

IMPORTANT

It is recommended that the Excel 12 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.

CAUTION

To avoid electrical shock or equipment damage, you must turn off the power supply before attaching / removing connections to/from any terminals.

MOUNTING

The unit is available with either short (W x L x H =

126 x 76 x 110 mm) or long (W x L x H = 180 x 76 x 110 mm) housings (see Fig. 1). The mounting procedures are similar for both sizes.

The unit is suitable for mounting on a standard rail (DIN EN 50022-35 x 7,5) and for installation in wiring cabinets, in fuse boxes, and on walls/ceilings.

DIN Rail Mounting/Dismounting

The unit can be mounted onto a DIN rail simply by snapping it into place and securing it with a stopper to prevent sliding. It is dismounted by gently pulling the stirrup located in the base of the housing (see Fig. 2).

The unit can be mounted on walls or ceilings in any orientation desired. In the case of ceiling mounting, however, it should not be operated at ambient temperatures exceeding 45 °C. The unit is mounted by inserting 3.5-mm dowel screws through the corresponding screwing noses.

Optional Use of Terminal Covers

After mounting the unit onto the wall or ceiling, provide for cable access by snipping out the terminal protection covers' cut-out tabs and snap (by hand) the covers (available in packs of 8) into place onto the housing. To remove a cover, place a screwdriver in the leverage slot (see Fig. 10 on page 7) and pry it loose.

Terminal Assignment

The terminal blocks are arranged on two sides of the controller: the relay side and the low-voltage side.

The relay side consists of a single row of terminal blocks for the connection of cables to the relays. In the case of models with 230 Vac power supply, the 230 Vac power is also connected on this side.

The low-voltage side consists of two rows of terminal blocks for the connection of cables to all other input / outputs. In the case of models with 24 Vac power supply, the 24 Vac power supply is also connected on this side.

NOTE: According to VDE guidelines, it is not allowed to mix low-voltage and high-voltage signals on the relays.

NOTE: For controlling thermal actuators, we recommend using the 24 Vac models, which provide more current.

Every unit is equipped with a terminal assignment label on the top of the housing (see Fig. 4). The terminal assignment label is a plastic part displaying the maximum complement of I/O's.

The small sticker in the upper left corner provides modelspecific information, e.g. the date code, the type of power supply, that terminals 36-38 (triac outputs 5 and 6) are not connected, and that terminals 1, 2, 22, and 23 may be used as 24 Vac output terminals, only (secondary side of the builtin transformer).

Power Supply

General Information

NOTE: Local wiring guidelines (e.g. VDE 0100) may take precedence over recommendations provided in these installation instructions.

NOTE: To comply with CE requirements, devices having a voltage of 50...1000 Vac or 75...1500 Vdc but lacking a supply cord, plug, or other means for disconnecting from the power supply must have the means of disconnection incorporated in the fixed wiring. This means of disconnection must have a contact separation of at least 3 mm at all poles.

All wiring must comply with applicable electrical codes and ordinances. Refer to job or manufacturers’ drawings for details. Use a min. of 18 AWG (1.0 mm2) and a max. of 14 AWG (2.5 mm2) for all power wiring.

If power is supplied via a T terminal plug, individual Excel 12 modules can be disconnected from the power supply without disturbing the operation of other devices powered by the same source.

Models with 230 Vac Power Supply

Models with 230 Vac power supply are equipped with a builtin 24 Vac transformer, the secondary side of which can be used to power external devices. The max. current at the field device supply terminals and all triac outputs together must not exceed 300 mA continuous.

NOTE: Do not connect external 24 Vac on models with 230 V power supply!!

These models have a long housing (180 mm). The power supply (230 Vac [-15% / +10%], 50/60 Hz) is connected to terminals 43 and 44. Terminals 1, 2, 22, and 23 are connected to the secondary side of the built-in 24 Vac transformer; these terminals must not be used for connecting an external transformer. The terminals can be used to power e.g. an active sensor.

Fig. 5. Connection to 230 Vac power supply

NOTE: The max. current at the field device supply terminals and all triac outputs together must not exceed

300 mA continuous. Disregarding these limits can result in the destruction of the built-in transformer.

When not supplying external devices with 24 Vac, these models have a power consumption of under 17.5 VA.

Models with 24 Vac Power Supply

These models have a short housing (126 mm). The power supply (24 Vac [±20%], 50 or 60 Hz) is connected to terminals 1 and 2. Terminals 22 and 23 may be used to connect further devices to the same 24 Vac power supply.

NOTE: Do not reverse the polarity of the power connection cables and avoid ground loops (i.e. avoid connecting one field device to several XL12's) as this may result in short circuits damaging your device.
