Section 3 - Installation and Wiring
Instructions in this section and others may require special precautions to ensure the safety of the
personnel performing the operations. Notes, Cautions and Warnings that may cause potential
safety issues are indicated throughout this manual by symbols, please refer to Page 3 of this
manual to view and familiarize yourself with these safety message symbols. Figures 3.2 through
3.7 show the various housings and their dimensions.
Note: Make sure to calibrate and bench check the instruments prior to installation. Also, install
all instruments in their intended application before making any electrical connections. For
DIN rail mounted instruments, allow enough room for pivoting instruments vertically on the rail
for removal in applications involving multiple banks of units. To remove the unit from the DIN
rail you will need a simple tool such as a straight blade screwdriver. Insert the blade of the
screwdriver into the cavity at the bottom of the locking mechanism and rotate it. This will release
the locking mechanism from the DIN rail and allow you to remove the unit.

[HPP] (see gure 3.4) – When using two input sensors, Sensor 1
can be congured as 2-wire or 3-wire sensor. Sensor 2 is then restricted to
a 2-wire sensor.
Note: THZ

[DIN] (see gure 3.2) - When
using two input sensors you are
limited to 2-wire and/or 3-wire sensors.
4-wire sensors (RTDs) cannot be used.
Note: TDZ

– When using two input
sensors you are limited to 2-wire
