3-20 | IPS-4 Dual Bench (UV / IR) Analyzer
Connecting I/O Signals, Alarm Relay Contacts, and AC Power
The analog input/output signals, alarm relay contacts, and AC power
requirements are specific to each analyzer installation.
For AC electrical supply cable and conduit requirements, refer to –
and comply with – local wiring regulations and electrical codes for the
area.
Refer to the “Electromagnetic Compatibility (EMC)” page in the con-
tents section of this manual for information that discusses the EMC
Directive regarding techniques and wiring practices to be followed.
Electrical Connections
Termination points for power and all signals are located in the Disconnect
and Sample Line Junction box enclosures. Five metric M32 straight thread
conduit entries are provided on the bottom of the Disconnect enclosure.
Three additional entries on the right side of the disconnect enclosure are
used for heated sample line and HAG probe option connections, but may
be used for I/O wiring if these options are not installed.
Five metric M25 straight thread conduit entries are provided on the
Sample Line enclosure. (Two on the right, two on the bottom and one on
the left side of the enclosure. The conduit entries are for power, sample
line heater and RTD wiring. Note that unused holes must be plugged
with M25 or M32 hole plugs applicable to the enclosure. Do not use NPT
hole plugs with thread adapters. Only properly certified conduit connec-
tors must be used.
WIRING SEALS MUST BE LOCATED AT THE WALL OF THE
DISCONNECT ASSEMBLY ENCLOSURE. NO ADDITIONAL
ENTRIES CAN BE ADDED TO THE DISCONNECT
ENCLOSURE WITHOUT VOIDING THE CERTIFICATION.
Figure 3-5 illustrates the general locations of all customer termination
points, while the Interconnect Wiring drawing (part of the analyzer
Final “As-Built” drawings package) specifically details the signal,
relay contact, and AC power connection points. The Final “As-Built”
drawings are located in the analyzer Documentation Package.
