Chint ND16 Pilot Light ND16-22D/2 ND16-22CS ND16-22DS ND16-22FS ND16-22BS 24V 220V CHNT LED Indicator

1. General

Degree of protection: IP65,IP40,IP20(Buzzer);
Standard: IEC/EN60947-5-1

2. Operating conditions

2.1 Ambient temperature is -5℃~+40℃, the average temperature during 24 hours couldn’t exceed +35℃.
2.2 Altitude: ≤2000m.
2.3 Atmosphere condition:
Relative humidity of the atmosphere couldn’t exceed 50% when the highest temperature is +40℃; much higher relative humidity is allowable under the condition of lower temperature, for example, when the temperature reaches +20℃, the relative humidity is up to 90%. As for dews, which contingently appear due to change of temperature, special steps should be taken.
2.4 Pollution degree: 3
2.5 Overvoltage category: Ⅲ
2.6 Tightening torque is 0.8~1.2N·m for the cable terminals, and 1.5~1.8N·m for the fixing nut. Cross section of the cable
connection is 0.5~2.5mm2, and 8mm conductor length is eeded.
