4.3Installation work
For installation of the analyzer locker and the extractor, follow the piping instructions in Fig.
(1)Countermeasures for cold climate
(a)Freeze prevention of gas piping
(b)Freeze prevention of drain pot
(c)Freeze prevention of bypass and drain pipes
(2)Countermeasurement for vibration
When installing in a place where vibration is considerable, the locker should be floated on antivibration rubber pads.
4.4Connection of cables
Caution
•Request an installation company or your dealer to carry out wiring. If wiring is incomplete, shock hazard or injury may be caused.
•Class D grounding construction is mandatory. Otherwise, shock hazard may be caused.
<Caution for wiring company>
For preventing shock hazard, fire and injury, be sure to observe the following.
•Before wiring, be sure to turn off the primary power supply. If this is neglected, you may receive and electric shock.
•For grounding, use a 600
•Connect the power supply which meets the rating of product. Connection of other power supply may cause a fire.
•Select the diameter of input and output wires, which matches the rated current of gas analyzer.
•Be sure to use solderless terminals for connection to the input and output terminal block.
•Use the terminal block for branching the output wire.
•Be sure to fix the input and output wires onto the floor, wall surface, etc. and use a protective device for wires.
The
Note: Avoid connecting the analyzer power supply near devices such as
4.5Connection of pipes (refer to piping instructions in Fig.
(1)Connect gas pipe between the gas extractor and the analyzer inlet (sample gas inlet). Use a joint, etc. for ø10/ø8 Teflon pipe when connecting to ensure there will be no leakage.
(2)Additionally tighten the joint section if necessary
