6 Use

6.1 Before energizing the relay, confirm whether the voltage level and current value of the connected relay are consistent with the actual parameters, otherwise the relay may be damaged; check whether the relay is damaged during transportation and storage, and the relay screw fasteners should not be loose; There are damaged parts, please contact us to replace them.

6.2 The relay needs to be wired according to the wiring diagram. Note that the polarity of the start coil (I or U) and the return coil (UF) cannot be reversed.

6.3 For AC signal relays, RYF depends on the AC voltage. When 380VAC, RYF=10KΩ/20W, when 220VAC, RYF=0.
