Installation & Operation Instructions
1.Installation
- Panel Mounting: Cut a standard 91×91mm opening for the 96×96mm meter. Insert and secure with brackets.
- Wiring: Connect auxiliary power (AC/DC 85–265V).Wire the voltage input terminals (for three-phase, connect L1/L2/L3 phases; for single-phase, connect one phase and neutral).
- Power On: Apply power to confirm the LED display lights up normally.
2.Operation & Maintenance
- Always disconnect power before installation, wiring, or disassembly to avoid electric shock.
- Keep the meter away from water, high humidity, and corrosive environments.
- Do not exceed the rated input voltage range to prevent damage to the meter.
- Periodically check wiring connections for looseness or signs of overheating.
- Clean the display surface with a dry cloth; avoid using chemical solvents.
- If the model includes Modbus communication, check the RS485 connection terminals regularly for stable contact.
