AcuRev 1300
Choice of wire of power supply is AWG22-16 or 0.6-1.5mm2.
A fuse (typical 1A/250Vac) or small air circuit breaker should be used in the auxillary
power supply loop. Such as the use of small air circuit breaker, it is recommended to use
IEC947 standards and through the CE certification of products. An isolated transformer
or EMC lter should be used in the control power supply loop if there is a power quality
problem in the power supply.
Note: the power before wiring, please confirm that the current power supply and
instrument brand logo on the power supply voltage is up!
Voltage Input:
Maximum input voltage for the AcuRev1300 series meter shall not exceed
400LN/690LL VAC rms for three phase or 400LN VAC rms for single phase. Voltage input
signal circuit must be installed in the air circuit breaker, fuse or small suggestion with 1 a
fuse.
Potential Transformer (PT) must be used for high voltage systems. Typical secondary
output for PTs shall be 100V or 120V. Please make sure to select an appropriate PT to
maintain the measurement accuracy of the meter. When connecting using the star
configuration wiring method, the PT's primary side rated voltage should be equal to or
close to the phase voltage of the system to utilize the full range of the PT. When connecting
using the delta conguration wiring method, the PT's primary side rated voltage should
be equal to or close to the line voltage of the system. A fuse (typical 1A/250Vac) should be
used in the voltage input loop. The wire for voltage input is AWG16-12 or 1.3-2.0mm2.
