Trumeter APM CT Meter User manual

APM
CT Meter
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.
DIP Switches
The DIP switches are on the back of the unit.

Use the DIP switch to set the CT Meter bar graph range,
and the current transformer (CT) ratio if used. The CT
ratio is shown as the target value. Use the software to set
other value CTs.

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.
