CAUTION: Risk of Danger
Read complete instructions prior to installation
and operation of the unit
CAUTION: Risk of electric shock
Before installation, read the Safety Warnings
overleaf.
Intended Use: The APM has been specifically designed for engineers
requiring an effective way to monitor and display data. The APM
accepts a range of electrical inputs (depending on the model) and
displays the data on its integrated multi-format display. The APM has
been designed for installation into electrical cabinets or display
panels. Output models include two independent outputs that can be
configured by the user to be either digital set-point outputs or 4-20mA
monitor outputs.
Operating SpecificationOperating Specification
Use the DIP switches to set the Temperature Meter bar graph range
and annunciators to standard values. Use the software application to
configure custom settings.
The switch positions are shown in the table where:
0 = OFF and 1 = ON.

Safety Warnings
WARNING: INSTALLATION AND MAINTENANCE
MUST BE CARRIED OUT BY SUITABLY
QUALIFIED AND COMPETENT PERSONEL ONLY.
HAZARDOUS VOLTAGES MAY BE PRESENT ON
THE CONNECTION TERMINALS.
INSTALLATION
• Install this product in accordance with local regulations, codes
and instructions.
• All fuses must be 0.5A / 250V Type F with a breaking capacity
of 35A or greater.
• All conductors carrying
switching or
3 mm of contact separation in all poles.
• Signal cables connected to this device must not exceed 30
metres long.
• If signal cables are routed outside the building, install extra
surge-protection devices.
• Power supply, current input, USB and all outputs: Observe
maximum allowable voltages. All circuits connected to these
connectors must be limited-energy and insulated by double/
reinforced insulation from mains voltages according to IEC
61010-1:2010
disconnect mechanisms fitted that provide at least
hazardous voltage
must have external
Failure to install or operate the unit in
accordance with the above requirements may
impair the electrical safety of the unit. Voltage
measurements: An external UL recognized or
listed overcurrent protection device (fuse or
circuit breaker) must be fitted in-line with the
voltage lead. Recommended fuse: 0.5A Type F
with a breaking capacity of 35A or greater. Fuse
voltage rating must be greater than the maximum
voltage that will be applied to the meter.
MAINTENANCE
• Before cleaning, inspection or maintenance, isolate all power
sources to the unit.
• There are no user-serviceable parts inside this unit. Never
open the case.
• Inspect all external wiring connections at regular intervals.
Replace any damaged
connections.
• To clean
• Take great care connecting the supply. If you connect power
to the wrong terminals, it may destroy the unit.
