1.7 Mounting the Hygrometer System

Mounting the hygrometer system consists of mounting the electronics unit, the probes, and the sample
systems.

1.7.1 Mounting the Electronics Unit

Use the outline and dimension drawings in the Certification and Safety Statements at the end of this manual to
mount the moisture.IQ. These drawings provide clearance and other mounting dimensions needed to prepare
the site for mounting.
WARNING! If the power mains switch on the unit remains accessible to the user after installation, a
disconnect device is not required. However, if the installation blocks access to the power mains switch,
compliance with the EU's Low Voltage Directive (IEC 61010) 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.
Be sure to follow the guidelines outlined in "Choosing an Installation Site" on page 2 before mounting the
enclosure.
Note: If the installation location does not provide enough room for connections to be made easily after
installation, you may want to make connections to the MIS or M-Series probes, Delta F Oxygen Cell,
Outputs and Alarms before mounting the instrument.

1.7.2 Mounting a Sample System

BHGE sample systems are normally fastened to a metal plate that has four mounting holes. BHGE can also
provide the sample system in an enclosure, if requested. In either case, fasten the sample system plate or
enclosure with bolts in the mounting holes at each of the four corners. If you ordered sample system outline
and dimension drawings, they will be included in your shipment.
Connect the sample system inlet to the process and the outlet to the return, using the appropriate fittings or an
appropriate NPT adapter.
CAUTION! Do not start a flow through the sample system until all probes and transmitters are
properly installed.
