The module must be installed in such a way as to meet electrical safety requirements and prevent accidental contact of contacts under high voltage. The module must be operated under recommended environmental conditions. | The module must be installed in such a way as to meet electrical safety requirements and prevent accidental contact of contacts under high voltage.

== | == Relay operation mode in case of power failure == | ||
Depending on the value written to the storage register 0x06, after the power is turned off and restored, the relays will remain off (if the value is 0, or turn on those that were turned on before the power interruption if the register has a value of 1). This feature appeared in the modules with the firmware, starting with version 1.5.3. | |||

Details of the work with the module via Modbus Protocol is written in [[Relay Module Modbus Management/en| Relay Modules Modbus Management ]]. | |||
You can also find a map of the device registers there. | |||
