Fig 2.8 Wiring of Power Supply
A fuse (typical 1A/250Vac) should be used in the auxiliary power supply
loop. No.24 terminal must be connected to the safety earth system of
switchgear. An isolated transformer or EMI filter should be used in the auxiliary
power supply loop if there is a power quality problem in the power supply.

.
Note: A filter should be used if there is an EMI problem.
Voltage Input
Meter input voltage should be 40~230Vac L-N,
60~400Vac. L-L. The voltage input could be directly
connected to the meter terminal without the use of PT if
the voltage system is less than 400Vac (L-L). If the input
Voltage is higher than 400Vac, a PT or VT should be

Make sure the power
supply voltage is the
same as what the meter
needs for its auxiliary
