14 15InstallationCautions for Proper Use(1) Because the control circuit is sensitive to temperature and impact, read this instructionmanual carefully for proper installation.(2) The brushless amplifier switches the power element at a high speed to control themotor. When the motor runs, leaking current will increase, which may activate theleakage breaker. If this is the case, use a leakage breaker provided with measureagainst high frequency for inverter.(3) To start and stop the brushless motor, use the RUN switch on the front panel or theRUN command input (see the function of terminal on page 20).Avoid operating the motor by turning on / off the power supply, since the life of theinternal circuit will be shortened.Installation of brushless amplifier• Install the product up and down correctly in the direction shown below.• Tightening torque of the product mounting screw should be selected appropriately soas not to be loose or damaged considering the strength of the screw to be used andthe material of the installation destination.Recommended tightening torque (When install to steel plate with steel screw):M4 0.8 N・m to 1.2 N・m• In order to cool effectively, please secure ambient space.• Measure the ambient temperature 50 mm away from the side and bottom of thebrushless amplifier.If measurement can not be made at 50 mm distance, including when using brushlessamplifiers side by side, measure at the midpoint of the gap between the obstacle andthe brushless amplifier or the gap between the brushless amplifier and the adjacentbrushless amplifier.When the motor is driven, the brushless amplifier generates heat, but be sure to keepthe temperature within the range including the heat generation.• Install in an environment where the pollution degree around the product is 2 or less,such as putting it in a control panel with IP 54 or higher.VerticalLocation of fixing screwLocation of fixing screwCaution
