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.

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 Excel 12 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 Excel 12 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 mm
14 AWG (2.5 mm
2
) 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.
