WARNING - READ BEFORE INSTALLATION
Vaisala Differential Pressure Transmitter PDT102 is a high-performance
instrument designed primarily for use in life science and cleanroom
applications. PDT102 is not authorized for use as a critical component in life
support devices or systems. Consult Vaisala before installing if there are any
questions or concerns.
Overpressure: Pressure spikes in excess of the rated overpressure capability
of the transmitter may cause irreversible electrical and/or mechanical damage
to the transmitter.
Static electrical charges: To avoid damage to the transmitter the
operator/installer should follow proper ESD (electrostatic discharge)
protection procedures.

MOUNTING
When securing to EN50022 rail first hook the top portion of the rear clip onto
the top of the rail and push gently into place. To remove, simply place finger
behind lower rear lever and pull forward. To remove from the EN50035 rail,
grasp the unit, push up, and rotate the bottom out. For the EN50045, pull
down and rotate the bottom out.
Multiple units can be stacked across the rail. Internal circuitry is vented
through the bottom of each unit. Tag holes are fabricated into the lower rear
lever and the housing below the terminal strip for calibration reference tagging
and/or ID location.
