Protective chassis and ground connections
Before connecting any electrical signal or power, the protective and chassis
grounds must be connected. Requirements for the protective and chassis
grounds are as follows:
•
The protective and chassis grounds must be of equal or greater size
than any other current-carrying conductors, including the heater
located in the sample conditioning system.
•
The protective and chassis grounds must remain connected until all
other wiring is removed.
•
If the protective and chassis ground is insulated, it must use the
green/yellow color.
Refer to Figure 1–1 and Figure 1–2 for the protective and chassis ground
locations.
Connecting electrical power to the analyzer
1.
Open the OXY5500 analyzer electronics enclosure door. Take care
not to disturb the electrical assembly inside.
2.
Run conduit or armored braided cable from the power distribution
panel to the conduit hub on the right side of the analyzer enclosure
labeled for power input.
Hazardous voltage and risk of electric shock
.
Failure to
properly ground the analyzer may create a high-voltage shock
hazard.
Conduit seals or Ex e cable gland should be used where
appropriate in compliance with local regulations.
Because the breaker in the power distribution panel or switch will
be the primary means of disconnecting the power from the
analyzer, the power distribution panel should be located in close
proximity to the equipment and within easy reach of the operator,
or within 3 meters (10 feet) of the analyzer.
The electrical installation to which the analyzer is connected must
be protected against transients. The protective device has to be
set at a level not exceeding 140% of the peak rated voltage
values at the power supply terminals.
