1.5 Wiring
CAUTION: The IAC-24 requires 24VDC. It will fail if 120VAC is used for power. Consult the factory for
directions to convert from an AC to a DC autocalibration system.
The IAC-24 requires a special electrical connector. This is purchased separately as an integral part of
the cable. For a new installation of the ZR402G and ZR22G system the WZ-H-6H-[ ] heater cable should
be used with the analyzer/detector combination. This cable has the wire and connections for both the
detector heater and the 24VDC autocalibration accessory. This cable may be used with both the
ZR402G single point analyzer and the AV550G multipoint analyzer.
