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.
• An external fuse must be fitted in-line with the PSU. Recommended fuse: 0.5A/300V
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.
• Observe maximum allowable voltages. USB, Modbus and output must be limited
energy and insulated from voltage and current inputs by double/reinforced insulation
according to IEC 61010-1:2010.
• All current transformers must be certified to IEC 61010-1:2010
• To reduce risk of electric shock always disconnect the power circuit being monitored
before installing or servicing current transformers.
• If this device is used outside it must be installed in an IP65 rated enclosure.
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
