Ac Power Connections - Ametek 241CE II User Manual

AC Power Connections

The analyzer must be operated from a grounded power source; failure to
do so will void the certification and the warranty. Depending on analyzer
configuration, the supply voltage may be 120 VAC, ±10 % maximum, 50/60 Hz
or 240 VAC, ±10 % maximum, 50/60 Hz. AC electrical supply wiring to ex-
ceed 80 °C (176 °F). The nominal operating voltage and power consumption
is indicated on a label on the front of the Electronics Enclosure. Verify that the
operating voltage indicated on the label agrees with the operating voltage
indicated on the documentation supplied with the analyzer. The analyzer is in-
tended for use in Installation Category II (Overvoltage Category) and AC power
requirements for each analyzer system are specified on the system electrical
drawings.
2-26 | 241CE II Hydrocarbon Dewpoint Analyzer
Both the North American and European versions of the 241CE II Ana-
lyzer require a power-disconnect switch (breaker), rated for at least
250 VAC, 3 A and certified for the hazardous location (to satisfy local
electrical codes, the switch must be certified by the local authority for
the appropriate hazardous location). The power-disconnect switch
(breaker) must be connected to and mounted near the analyzer, in
an easily accessible area. The switch (breaker) must be clearly labeled
(e.g., "AMETEK 241CE II Analyzer Main AC Power Disconnect Switch").
For safety reasons during maintenance, this switch allows the main
AC power to be disconnected from the analyzer prior to performing
service on the analyzer. This switch (breaker) is to be supplied by
the customer/end user.
See the Electromagnetic Compatibility (EMC) page in the contents sec-
tion of this manual for information that discusses the EMC Directive
regarding techniques and wiring practices to be followed.
