WARNING
The following power requirements must be met by the installer of the DC/AC power connections to the
Analyzer:
•You must include an electrical disconnect means and a current limiting device, such as a
switch and fuse. The disconnect device must be marked as a 'disconnect device' and
readily accessible to shut off power to the Analyzer. This will allow the Analyzer to be
quickly shut-off in case of an emergency. The disconnect and current limiting device must
be housed in an enclosure rated for the area classification. Conduit seals may be required
on the enclosure, depending on the area classification.
DC-powered version
Use a 0.25-Amp fuse disconnect.
AC-powered version
Use a 0.20-Amp fuse disconnect.
The voltage rating for the AC Analyzer is 100 to 240VAC at 50/60Hz ± 10%.
AC voltages outside this may cause the Analyzer to malfunction.
You must follow the National Electrical Code (NEC) in your installation. Consult the NEC Handbook
for the correct guidelines and standards.
Class I, Div 1 areas must use rigid conduit with seal-offs.
Class I, Div. 2 areas can use flexible conduit with seal-offs.
The Analyzer has approval for Class I, Division 1, Groups B,C,D. To comply with these
requirements, you need to assure the following:
•The Protective Earth Ground Lug on the front lower left of the Analyzer mounting bracket
must be connected to the High Quality Protective Earth Ground using a16-gauge wire.
Please refer to the image on page 2 of the front view of the Analyzer for the location of the
Protective Earth Ground Lug
