3-26 | Model 241CE II Hydrocarbon Dewpoint Analyzer
AC Power Connections
Both the North American and European versions of the Model
241CE II Analyzer 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 Model 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. is switch (breaker) is to be supplied by
the customer/end user.
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 % max., 50/60 Hz
or 240 VAC, ± 10 % max., 50/60 Hz. AC electrical supply wiring to exceed
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 intended for use in Installation Category II (Overvoltage Cat-
egory) and AC power requirements for each analyzer system are specified
on the system electrical drawings.
