◎
Make sure all modules are operating within their electrical specifications, and the combined operation output power must be less than
the Front-End's maximum output rating: (1200W for NMP1K2; 650W for NMP650)
.
◎
When operated under normal conditions, the NMP has a 5-year global warranty. Please do not change components or make
modifications to the product, otherwise the warranty shall be void.
◎
When the ambient temperature is high or input AC voltage is low, the power supply needs to be de-rated according to curves shown below.

Front-End Mounting
Output wire gauge should be appropriately sized based on the output current of each module. The table below shows the minimum
wire gauge required for the corresponding current. It is recommended to use red wire for +V and black wire for -V.
