Chapter3:

Installation of the Instrument

3.1 Unpacking

The analyzer should be unpacked with great care.

Watch for any loose accessories.

3.2 Inspection

The analyzer has been factory checked and tested prior

to shipment. It is advisable, however, to inspect all

parts immediately upon receipt for any damage which

may have occurred during shipping. A damaged ship-

ping container may indicate internal damage, which

may not be immediately obvious. If there is any evi-

dence of damage, keep the shipping container and

refer to your local agent or to:

3.3 Mounting

3.4 Location

The analyzer should be located in an accessible site.

The site should permit access for any inspection or

maintenance operation.

3.5 Power Connection

For safety reasons, it is required to observe the pre-

cautions below:

1. The instrument should be connected to the power

supply by means of a breaker located close to the

instrument and clearly identified.

2. This breaker should switch off phase and neutral in

case of electrical problems or to service the instru-

ment. However, the earth ground must always be con-

nected.

3.6 Starting the Transmitter

Before switching on the transmitter, make sure the

site voltage corresponds to the instrument voltage

indicated on the identification plate.

3.7 Adjusting the Display Contrast

If the display contrast is not sufficient, adjust the

potentiometer P1 (blue color, see figure on page

3-2), which is located on the top left of the CPU

board (after opening the enclosure).

CAUTION!

Mounting should be done by

qualified service personnel only.
