INSTALLATION
WARNING
Please familiarize yourself with this entire section before beginning
installation. Failing to do so may adversely affect the performance of the
instrument and/or violate local legislation.
3.1 Unpacking and visual checking
Take all standard precautions when opening packages. In particular avoid the use of long
bladed cutters. Search packing before discarding it to ensure that all of the components have
been removed. Check that all pipe connections have captive seal nuts.
WARNING
RECOMMENDED TWO-MAN LIFT:
The K1550 EEx d instrument weighs
approximately 25kg excluding packaging. Observe appropriate manual
handling precautions when unpacking / installing the analyser.
3.2 Siting
The K1650 instrument is designed principally for panel mounting (see Figure 1), with a
remote sensor installed in a GRP enclosure (see Figure 2). It may also be provided in an
EEx d certified enclosure for applications where the instrument also needs to mounted in a
hazardous atmosphere (see Figure 3).
The K6050 is a portable instrument mounted in a rugged case. See Figure 4.
Ensure that the environmental requirements of Section 2.13 are met.
3.3 Electrical connections
3.3.1 K1650
Three plug-in terminal blocks are provided at the rear of the instrument.
Refer to Figure 1 for details.
WARNING
K1650 instruments must be installed with a disconnecting switch close by,
within easy reach of the operator and compliant with the relevant parts of IEC
60947-1 and IEC 60947-3. It must be marked to indicate this function and show
ON and OFF positions. Wiring should conform to local codes.
Only the live conductor has an internal equipment fuse. European regulations
recommend that fuses be fitted in both the live and neutral of the mains supply
to the instrument.
NOTE
The relay operation and labelling ‘Normal’ relates to process normal and not the electrical
rest position of the relays, In process normal the relays are energised (refer to figure 11).
3.3.2 K6050
Connections consist of a charge socket (connect only the supplied charger) and 4mm sockets
for analogue output.
3.3.3 Routing of wires
To minimise the pick-up of electrical noise all signal wiring should be routed away from power
cables. The K1650 is shipped with a pre-assembled sensor cable. See Section 4.7 for details.
