4 Installation and connection

4.1 Installation site requirements

The following requirements must be met during installation:
• Never install the device near sources of heat or vibration,
in direct sunlight, or near high frequencies or magnetic
fields. The operator must install a lightning arrester and
overvoltage protection.
• Consider the electromagnetic compatibility of nearby
equipment when selecting the installation site.
• To maintain electrical safety, never operate the device in
atmospheres with an oxygen content above 21 %.
• The device must be anchored to the wall, which must be
able to support the weight.
• Please refer to chapter Appendix/Technical Data for the
max. ambient temperature. Operation outside the limits
will void the warranty for this device.
• Do not obstruct the convection of the device. Leave ad-
equate space between the vents and the nearest object.
The clearance must especially be a minimum of 10 cm on
the air outlet side. The air intake and outlet must be clear.
Heat may otherwise build up.
• Protect from shock and impact.
• Never expose the display components to external forces.
• Never install the device outdoors.
DANGER
Potentially explosive atmosphere
Explosion hazard if used in hazardous areas.
The device is not suitable for operation in hazardous areas
with potentially explosive atmospheres.
Do not expose the device to combustible or explosive gas mix-
tures.
4.2 Installation
Install the device in the specified position, see chapter Dimen-
sions (mm).

CAUTION
Damage/installation
Avoid damage to the product. Handle the product with care.
If wall brackets are required for installing the device, ensure
these meet DIN EN 61010-1.
NOTICE
Please note:
At the time of delivery, the device has a leak rate of less than
1.5 mbar/h at a test pressure of 160 mbar and an ambient
temperature of 20 °C.
Check the system for leaks following transport and installa-
tion before starting it. The operator must include this in his
risk/safety assessment and if necessary take additional meas-
ures to prevent explosion and/or health hazards.
When changing the factory settings, please document the
factory presets as well as the changed values.

4.3 Electrical connections

All connection lines can be fed into the device through the
cable glands at the bottom.
Include strain relief for the connection cables. The supply line
cross-sections must be suitable for the rated current and meet
local regulations.
The signal and supply lines of the device must be properly
connected.
Please note the clamping points of the following cable glands:
Thread Clamping range
M25 11.0mm – 17.0mm
M20 6.0mm – 12.0mm
Run the lines so the insulation will not be damaged. If neces-
sary, secure the lines with suitable means and avoid excess
line lengths.
The power supply must be connected as per chapter Connec-
tion [} 12] or per the wiring diagrams.
The power and voltage supply for the components may re-
quire the following separators:
RCD, main switch and circuit breaker or fuses
If applicable, the following requirements must be met for op-
eration:
• The RCD must shut off the load within the prescribed
period (200 ms at 115 VAC, 40 ms at 230 VAC). It must be
suitable for the maximum load.
• The main switch must be installed near the device, easy to
access and marked as a separator.
• The circuit breaker/fuses protect all supply lines but not
the earth conductor.
The fuses should be arranged side by side, have the same rat-
ing/characteristic, and not be connected to the neutral wire of
multi-phase equipment.
Please refer to chapter Technical Data for the applicable sep-
arator data.
