Installing The Cooler Into A Housing; Electrical Connections - Bühler technologies TC-Standard OEM Guía Rápida

ance must especially be a minimum of 10 cm on the air outlet
side. The air intake and outlet must be clear. Heat may other-
wise build up.
Only install the sample gas cooler in ventilated housings. We
recommend a minimum of IP protection class 24.

4.2 Installing the cooler into a housing

Please refer to the drawings in chapter Dimensions (mm) for
the installation dimensions of the respective version of the TC-
Standard OEM. Plan for the respective mounting holes at the
installation site.
A suitable opening for the display module must be provided
in the front panel of the housing. To a secure fit, we recom-
mend a front panel thickness between 1.5 mm and 4 mm.
Display unit
The ribbon cable must be plugged into the plug connections
for the display and into the electronics board.

4.3 Installation
Run the gas supply to the cooler with a downward slope. The
gas inputs are marked in red and additionally labelled "IN".
If a large amount of condensate accumulates, we recommend
using a condensate trap with automatic condensate drain.
Our condensate drains, 11 LD V38, AK 20, AK 5.5 OR AK 5.2, are
suitable.
Glass vessels and automatic condensate drains are available
for draining condensate for external mounting below the
unit. When using automatic condensate drains, the sample
gas pump must be installed upstream of the cooler (pressure
operation) to ensure proper function of the condensate drain.
If the sample gas pump is located at the cooler outlet (suction
operation), we recommend using glass condensate traps or
peristaltic pumps.

Connecting the condensate drain
Depending on the material, build a connecting line with fit-
tings and tubing or hose between the heat exchanger and
condensate drain. For stainless steel the condensate drain can
be hung directly from the connecting tube, for hoses the con-
densate drain must be secured separately using a clamp.
The condensate drain can be mounted directly to the heat ex-
changer.
Condensate lines must always be installed with a slope and a
minimum inside diameter of 6 mm (1/4").
The MTG heat exchanger (in coolers with 2 heat exchangers)
can only be operated with peristaltic pumps.

4.4 Electrical connections

The operator must install an external separator for the device
which is clearly assigned to this device.
This separator
• must be located near the device,
• must be easy for the operator to reach,
• must comply with IEC 60947-1 and IEC 60947-3,
• must separate all live conductors and the status output,
and
• must not be attached to the power feed.
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 installed according to the following
wiring diagrams and have the respective voltage.
WARNING
Hazardous electrical voltage
The device must be installed by trained staff only.
CAUTION
Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
Particularly maintain a discharge time of at least 5 seconds
after switching off the power supply on the version with
switching power supply.
