OUTLINE DIMENSIONS
CAUTION
1. Please avoid installing in strong magnetic fields (transformers, magnets around) or hot objects.
2. Use the environment temperature -40ºC~+85ºC, humidity 5%~85%RH.
3. Electrical life test under L/R ≤1ms condition.
4. Please be attention: If parallel diode on coil will increase relay release time and decrease electrical life.
5. Please avoid the adhesion of oil and other foreign material on the lead sheet, please use the cable with 100mm2 or above, otherwise it may cause the abnormal fever in the lead-out part.
6. In order to prevent loosening, please use the washer screw to lock when the relay is installed, and the screw locking torque of each part should be controlled in the following range: a) Relay shell installation department Recommend M5 screw: 3N.m~4N.m b) Main loading installation part Recommend M6 screw: 6N.m~8N.m
7. When screw installation, depth of match should not be too shallow, otherwise may lead to screw loose, recommend 2/3 of length of thread at least. 8. Relay installation baseboard hole can't be chamfered too much, recommend Ø5.5mm, otherwise relay shell bushes will loose, please refer to below:
