SS2100i-1 Analyzer
3–2 4900002260 rev. B 12-20-17
The SS2100i-1 is intended to be mounted to a wall or secured upright frame.
Secure the analyzer frame in position using bolts or screws of the size indicated
in the system drawings.
Protective chassis ground connections
Before connecting any electrical signal or power, the chassis grounds must be
connected. Safety 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 system drawings for exact locations of the chassis ground connections.
1. Connect the chassis ground to the marked bottom right corner of the
right-side enclosure.
2. Connect the chassis ground to the lower left corner of the underside
of the enclosure.
3. Connect the system ground to the ground bus bar as shown in Figure
5–2 during the electrical power connection. Refer to the SS2100i-1
Hardware Installation and Maintenance Manual (P/N 4900002224)
for instruction.
Electrical Wiring Requirements
It is critical to mount the analyzer so that the supply and return
lines reach the supply and return connections on the chassis,
while still maintaining flexibility, so that the sample lines are not
under excessive stress.
Failure to properly ground the analyzer may create a high-voltage
shock hazard.
Interconnection of the analyzer enclosure and cell enclosure shall
be accomplished using wiring methods approved for Class 1,
Division 2 hazardous locations as per the Canadian Electrical Code
(CEC) Appendix J and the National Electric Code (NEC) Article
501, or methods described in the Standard IEC/EN 60079-0 and
IEC/EN60079-14. The installer is responsible for complying with
all local installation codes.
