Base Unit / Fan Unit

Pay attention to the following items to install the base unit and the fan unit.
 The controller unit is not dust-proof. Store it in the control board that takes
dust-proof into consideration as much as possible.
 Avoid installing it directly above devices that generate lots of heat (such as
heater, transformer and large capacity resistor).
 Do not install it on the same board as the high-voltage devices.
 Put it off the high-voltage wire and the power wire at least 200mm.
 Reserve at least 70mm space for ventilation around the base unit and the fan
unit.
 Put if off high-voltage and power devices as far as possible considering
maintenance and operational safety or block it off with steel plate.
 To install the extended base unit, contact it to the metal frame and fix it so that
the electric potential of the base unit is equal to that of the extended base unit.
 Take grounding into consideration especially near high-voltage and power
devices.
 Install the base unit and the fan unit on the vertical panel surface.
 Use four of M4 screws to install the base unit and the fan unit firmly (rough
indication of tightening torque: 1.47N・m=15kgf・cm).
 Install the back cover of the base unit before installing the base unit on the
control board and tighten screws.
The dimension to install the base unit is shown in the following figure.
