4.3 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.
• The ELCB (tripping current 30 mA) must shut off the load
within the required amount of time. It must be suitable
for the maximum load.
An additional, or integrated in the separator, overcurrent
device is required. All feeders except the ELCB must have over-
current devices, e.g. circuit breakers or fuses. This should be
next to each other, have the same rating, and not be integ-
rated in the neutral wire of multi-phase equipment.
Please refer to chapter "Technical Data" for the applicable sep-
arator data.
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.
Plug connection
The device must be operated on 230 V AC or 24 V DC as spe-
cified in the type plate. The device has an EN 175301-803 power
plug. If the lead is connected correctly, these cannot be con-
fused. Therefore please be sure to correctly reassemble the
plugs after connecting the wires. Below you will find the pin
assignments, with the numbers corresponding to those on the
plugs:

5 Operation and control
NOTICE
The device must not be operated beyond its specifications.
The unit is ready after switching on the precooler. Check for
leaks before switching it on. When using a peristaltic pump,
the pump must be on before adding sample gas. When using
the optional acid meter, be sure the dosing pump was started
at least 15 minutes (with a 3 m standard line) prior to taking
measurement and moistens the glass beads in the process.
Depending on the line length the flow time may vary, the cal-
culation uses 5 minutes per metre.
Please refer to the data sheet for performance data and max-
imum ratings.
6 Maintenance
Always observe the applicable safety- and operating regula-
tions when performing any type of maintenance. Please refer

at www.buehler-technologies.com for maintenance informa-
tion.
7 Service and Repair
