In order to prevent the internal temperature of the machine from overheating, please use the wall-mounted installation. It is required to leave enough space above and below as a heat dissipation space. 2. Leave a gap of more than 50mm between the programmable controller host and other equipment or structures. Keep away from high-voltage lines, high-voltage equipment and power equipment as much as possible. 3. Avoid dust, oil, and corrosive environments; pay attention to electrostatic protection (avoid direct contact with the circuit board circuit with your hands). Adopt rail installation. Size(LxWxH): Approx. 88 x 138 x 62mm / 3.5 x 5.4 x 2.4in. Package List: 1 x PLC Control Board1 x User Manual
