Trumeter Shunt Series User manual

APM
SHUNT METER
* Non-Isolated,
for Low Side
DC Applications
Only *
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.

Use the DIP switches to set the Shunt 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 hazardous voltage must have external switching or
disconnect mechanisms fitted that provide at least 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
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
wiring and tighten any loose connections.
•To clean the unit, use a dry cloth to wipe the casing.
•Take great care connecting the supply. If you connect power to the wrong terminals,
it may destroy the unit.
