50 Installation and Disassembly
CFPP Process Analyzer CFPP-4.2 03/2016
Before making any electrical connections, observe the following:
1. The power supply to the analyzer must be equipped with a separator that allows it to
be safely disconnected from the power supply. Use a separator which disconnects all-
polo and which can be locked and secured. The separator must be installed near the
analyzer and must be easily accessible. It must be clearly marked so that it can be
identified as belonging to the analyzer.
2. The power supply to the analyzer must be equipped with a fuse, as specified in the
technical data (see chapter 4).
3. All important information for installation can be found in the supplied electrical
documentation and in the wiring diagram.
4. Before starting work, make sure that the voltage of the power supply matches the
required voltage shown on the instrument type plate.
5. If intrinsically-safe operating equipment which is not part of the analyzer (e.g. for
signal transfer) is supplied with power from the cabinet, ensure that all capacities and
inductivities are below the specified limits.
6. Make sure that only screened cable is used for control connections. Check the polarity
of the signal cables.
To make the electrical connections, proceed as follows:
• Connect the analyzer to the local equipotential bonding, using cable with at least
16 mm
2
cross section. The position of the connectors on the frame can be found in
the supplied layout drawing.
• Open the power supply box and the signal junction box.
• Thread the cables through the provided cable glands into the junction boxes.
• Connect the ground wire and the power and signal cables according to the
information in the supplied plan of terminal connections.
• Pull tight the cable glands.
• Close any unused cable glands and bores for cable glands.
• Replace the protective covers on the terminals.
• Close the junction boxes.
• Lock the power supply box by using a double-bit key. Secure the cover of the signal
junction box with the fastening screws.
The electrical connections are complete. The analyzer is now ready to be put into
operation (see chapter 8).
