Installation
400V Models
The ambient temperature of the operating environment for the 400V servo drive is between 0°C
2
(32°F) and 55°C (131°F). When operating the 3 kW models in an ambient temperature between
50°C (122°F) and 55°C (131°F), reduce the maximum load to 80%. If the temperature is over
45°C (113°F), place the product in a well-ventilated environment. During long-term operation,
the suggested temperature of the operating environment should be under 45°C (113°F) to
ensure the servo drive's performance. Mount the product vertically in the distribution board (see
the illustration of the correct mounting direction in Section 2.3) and install a fan on the board for
heat dissipation. Ensure that the temperature for the clearance of 5 cm (1.97 inches) beneath
and on both sides of the servo drive is kept under 50°C (122°F), and the servo drive must be
kept clear of heat sources. Moreover, the airflow velocity at the measuring point which is 10 mm
(0.4 inches) above the servo drive has to be greater than 1 m/s. Make sure the size of the
distribution board and its ventilation condition can prevent the internal electrical devices from
overheating. Besides, check if the vibration of the machine affects the electrical devices of the
distribution board.
