4 Nominal operation conditions
1: Ambient temp. range:-5℃~+40 ℃，average temperature in 24 hours not exceed +35℃
2: Altitude:≤ 2000m;
3: At mounting site, relative humidity not exceed 50% at the max temperature of +40 ℃，higher relative humidity is allowable under lower temperature, for example ,RH could be 90% at +20 ℃
4: Mounting type : Din rail embedded(TH35-7.5)
5: Installation conditions
Any direction of the outer magnetic field of the installation site should not exceed 5 times than earth's magnetic field; residual current operated circuit breaker should be mounted vertically, the installation place should be no significant impact and vibration.
