2.1 Installation
2.1.1 Introduction
This chapter provides a general description of the standard CGA 351 and gives directions on how to install and wire
the analyzer for proper operation.
Note: For information regarding component locations and/or wiring connections in an optional enclosure, see
Appendix C.
IMPORTANT: For compliance with the European Union’s Low Voltage Directive (73/23/EEC), the CGA 351 requires an
external power disconnect device such as a switch or circuit breaker. The disconnect device must be
marked as such, clearly visible, directly accessible, and located within 1.8 m (6 ft) of the unit.
WARNING!
Power up the CGA 351 as quickly as possible after introduction of the sample gas. If the analyzer is left
installed without power, the unit’s components become susceptible to acid condensation that will
cause corrosion.
Be sure to observe all installation limits and precautions described in this chapter. Pay particular attention to the
ambient temperature range of –25 to +50°C (–13 to +122°F) specified for the instrument.
WARNING!
To ensure safe operation of the CGA 351, the unit must be installed and operated as described in this
manual. Also,
be sure to follow all applicable local safety codes and regulations for installing electrical equipment.
In addition, all procedures should be performed
by trained service personnel.
