Correct wiring is critical. Miswiring the shunt or reversing polarity will damage the meter instantly. Terminal Breakdown
Understanding the exact operational limits prevents device failure and ensures accurate readings. DC 6.5V to 100V Do not exceed the rated voltage of 100V
The PZEM-051 typically has two input blocks on the main module:
This device connects directly to AC Mains power. Installation should only be performed by qualified personnel. Incorrect wiring can result in fire, equipment destruction, or lethal electric shock. Incorrect wiring can result in fire, equipment destruction,
: Connect the two small terminals on the shunt to the current input terminals on the back of the PZEM-051 meter . These are typically labeled 'I+' and 'I-' or similar. Ensure you maintain the correct polarity.
