Transient and RFI interference
Transient and noise protectors on I/O connections (communications, current
outputs, etc.) are intended to act as a last line of defense against unwanted
transient and RFI interference.
•
Follow proper installation practices. Inductive loads connected to the analyzer
must have transient suppressors installed at the inductive loads.
•
For optimum noise protection, connect the analyzer mains supply wiring to a
circuit separate from any that could introduce transients into the system.
Secondary Process Seals Requirement
"This instrument is supplied with a primary process seal only (single
seal device) in accordance with ANSI/ISA 12.27.01-2003. Proper
installation of this instrument requires a secondary process seal if
failure of the primary process seal could allow process fluids to enter
the conduit or field wiring system.
It is the user's responsibility to provide Secondary Process Seals to prevent
process fluids from migrating through the cable or conduit system to an
unclassified area. The seals must be installed on all conduit entry ports to the
analyzer at the customer-connection box to vent gas/fluids to a location where
they can be handled safely.
Connecting the 5100 HD to Mains Power
There is no power switch or circuit breaker in 5100 HD analyzer configured for
AC power. The analyzer must be protected by installing it on a circuit-protected
line, maximum 15 Amps, with a switch or circuit breaker close to the unit and
within easy reach of an operator. Use the 1/2" conduit entry port in the customer
connection box for the AC mains supply wiring. For the 24 VDC version, 4 amp
fuse is provided.
Mark the switch or circuit breaker as the disconnecting device.
NOTE
The Model 5100 HD analyzer supports 120 or 240 VAC, 50/60 Hz or
24 VDC.
