operation conditions refers to the ambient temperature and relative humidity value that

may occur during an air-conditioning system failure, and normal operation conditions

should be recovered within 5 hours.

2.1.1.3 Power Supply

It is adopted module switch power for the switch, the input parameters of power are

shown below:

The AC input voltage: 90~300VAC

The frequency: 47Hz ～ 63Hz

The DC input voltage: 12V/3.3A

Before powering on the power supply, please check the input power to ensure proper

grounding of the power supply system. The input power for the switch should be reliable

and secure; a voltage adaptor can be used if necessary. The building's circuit protection

system should include in the circuit a fuse or circuit-breaker of no greater than 240 V, 10 A.

It is recommended to use a UPS for more reliable power supplying. .

Caution!

Improper power supply system grounding, extreme fluctuation of the input source,

and transients (or spikes) can result in larger error rate, or even hardware damage!

Static electric can cause damage to internal circuits, even the entire switch. Follow

these guidelines for avoiding ESD damage:



Ensure proper earth grounding of the device;



Perform regular cleaning to reduce dust;



Maintain proper temperature and humidity;



Always wear an ESD wrist strap and antistatic uniform when in contact with circuit

boards.

2.1.1.5 Anti-interference

All sources of interference, whether from the device/system itself or the outside

environment, will affect operations in various ways, such as capacitive coupling, inductive

coupling, electromagnetic radiation, common impedance (including the grounding system)
