Installation, Commissioning and Operation

Before installing and operating the product, please read the Operation Manual
carefully to ensure correct use. If you have any questions, please contact our
After-sales Service Department in time.
When installing the product, please check if the specifications, model, voltage
and other parameters of the product are in compliance with the technical
requirements specified in the wiring diagrams.
Wiring and maintenance activities should be carried out only by qualified
personnel.
Never use the product beyond the specifications indicated on the nameplate,
otherwise it may result in damage to the switch or circuit hazards.
Input operating conditions:
Attention should be paid to the operating voltage range and the correct polarity
●
(positive and negative terminals).
To ensure the normal operation of SSRs, the input current should be increased
●
at a low ambient temperature, or reduced at a high ambient temperature.
When using integrated circuits (ICs) to directly drive SSRs, it is important to
●
ensure the IC has sufficient load capacity and "0" level output as low as possible.
Output operating conditions:
To ensure the reliable operation of SSRs, it is important to use their limit
●
parameters correctly and implement necessary protective measures.
Selection of peak voltage: inductive load: take 2-3 times the circuit voltage
●
(effective value); pure resistive load: take 1-2 times the circuit voltage (effective
value).
