3Installation
3.1 Incoming acceptance, transport, storage
The permitted ambient and storage conditions must be observed. The precise specifications
can be found in Section 10 "Technical data".
3.1.1 Incoming acceptance
On receipt of the goods, check the following points:
• Are the packaging or contents damaged?
• Is anything missing from the delivery? Compare the scope of delivery with the information
you specified in the order.
3.1.2 Transportation and storage
Note the following points:
• Pack the device so that is protected against impact for storage and transportation. The
original packaging provides optimum protection.
• The permitted storage temperature range is -40 to +85 °C (-40 to +185 °F); it is possible
to store the device in the limit temperature ranges for a limited period (maximum 48
hours).
3.2 Installation conditions
The device is designed to be used in a panel.
The orientation is determined by the readability of the display. Connections and outputs are
fitted on the rear of the device. The wires are connected by means of number-coded
terminals.
Operational temperature range:
Non-Ex/Ex devices: -20 to 60 °C (-4 to 140 °F)
UL devices: -20 to 50 °C (-4 to 122 °F)
NOTICE
The life-time of the display is shortened when the device is operated in the upper
temperature range.
‣To avoid heat accumulation, please always make sure the device is sufficiently cooled.
3.3 Dimensions
Observe the installation depth of 150 mm (5.91 inches) for the device incl. terminals and
fastening clips.
In the case of devices with Ex approval, the Ex frame provided is mandatory and an
installation depth of 175 mm (6.89 inches) must be observed. More dimensions can be
found in Section 10 "Technical data".
• Panel cutout: 92 x 45mm (3.62 x 1.77 in).
• Panel thickness: max. 26 mm (1 in).
• Max. viewing angle range: 45° to the left and right from the central display axis.
• If the devices are arranged horizontally beside one another in the X-direction, or arranged
vertically on top of one another in the Y-direction, the mechanical distance (specified by
the housing and front section) must be observed.

1. Screw the threaded rods (pos. 1) into the positions provided on the mounting frame
(pos. 2). Four opposing screw positions (pos. 3/4) are available for this purpose.
2. Push the device through the panel cutout from the front.
3. To secure the casing in the panel, hold the device in a horizontal position and push the
frame (pos. 2), with the threaded rods screwed in, over the casing until the frame locks
into position (1.).
4. Then tighten the threaded rods to fix the device in place (2.).
5. For the Ex option, install the distance piece (pos. 6) for the input terminals.
To disassemble the device, the mounting frame can be unlocked at the locking elements
(pos. 5) and then removed.

4 Wiring
WARNING
!
Danger through electric tension
‣Make sure that no voltage is supplied when wiring the device.
‣The protective ground connection must be established before any other connection is
made. A source of danger could arise if the protective ground connection is disconnected.
‣Provide a suitable switch or power-circuit breaker in the building installation. This switch
must be provided within easy reach of the device and be labelled as a disconnector.
NOTICE
Damage of the device through incorrect wiring or overvoltage
‣Use wires suitable for 5 °C (9 °F) above surrounding.
‣Prior to commissioning, make sure the supply voltage matches the specifications on the
nameplate (left side of the housing).
‣An overcurrent protection unit (nominal current ≤10 A) is required for the power cable.
‣Observe the terminal designation inside the device.
4.1 Connecting the device
A loop power supply (LPS) is provided for every input. The loop power supply is primarily
provided to supply power to 2-wire sensors and is galvanically isolated from the system and
the outputs.

Fig. 4: Rear view and terminal assignment of the device (relays (terminals Rx1-Rx3) and channel 2 (terminals 21-28 and O25/
O26) are optional)
It is permitted to connect a mixture of safety extra low voltage and voltage which
poses a shock hazard to the relays.
