Connect it directly to a three-phase 400V AC power supply. The STO safety circuit must be wired according to the machine's safety design and relevant regulations (e.g., ISO 13849-1). The self-cooled design requires adequate space around the unit for air circulation. Due to the IP00 rating, the cabinet must provide protection from environmental contaminants.\u003c\/p\u003e\n\u003ch3\u003eExpert FAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the primary purpose of the STO function?\u003c\/strong\u003e\u003cbr\u003eSTO is a safety feature that safely disables the motor torque, allowing for maintenance or intervention without unexpected startup, which is required for many modern safety-rated machines.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the \"A4\" and \"RJ070\" suffix indicate?\u003c\/strong\u003e\u003cbr\u003e\"A4\" typically denotes a 400V class amplifier. \"RJ070\" often specifies a particular regenerative braking resistor or a regional product variant.
