The TY series of electric energy meter boxes integrate single-phase and three-phase types, and are suitable for power supply systems with rated current of 10A-250A, AC 50Hz or 60Hz, and voltage of 220V to 690V, and perform single-phase and power electric energy metering and control tasks; its operating environment requires a temperature range of -25℃~+50℃ (average temperature ≤+35℃ within 24 hours), and the relative humidity does not exceed 80% at 40℃ under clean air conditions, and higher humidity levels are allowed under low temperature conditions.
Thoroughly check the structural integrity and component completeness of the cabinet before installation.
Do not contact with strong alkalis, oxidizing acids, amines, ketones, chlorinated hydrocarbons and aromatic solvents.
During use, be careful to prevent collisions and scratches with sharp objects to keep the surface protective layer intact.
Remove the central fixing screw at the bottom and open the box according to the standard process.
Locate the wall drilling point according to the preset hole position, lock the base after implanting the expansion tube, and perform final assembly of the upper cover.
