4.2 Soldering the Variable Resistor Terminals
Do the following to solder leads into place on the variable resistor terminals.
①
Pass the leads through the terminal hole and wrap around two to three times.
②
Solder the lead wire to the terminal.
③
Cover the soldered area with a heat shrink tube.
4.3 Installing the Variable Resistor
①
Insert the Variable resistor into the Mounting panel (insulation material) as shown in the figure below.
②
Put on the scale plate and inner clip washer and fasten with the Nut. (Tightening torque: 0.45N
･
m [4.5kgcm] max.)
③
Mount the Knob and fix it in place with the Stop screw M4. (Tightening torque: 0.4N
･
m [4kgcm] max.)
Note:
Do not run a series of fans off a single Variable resistor. Circuit damage may result.

4.1 Mounting the fan
To mount the fan, drill holes in the machinery in which it will be installed referring to Panel-Cut-Out (see General Catalog)
and then fasten the fan with screws (these must be furnished by the user).
Use screws of M5 to install the fan.
The recommended tightening torque for mounting is 1.2N
･
m (12 kgcm).
The direction of airflow is indicated by the AIRFLOW mark on the side of the fan frame.
The arrow points in the direction of the outlet. The rotation arrow indicates the direction of rotation.
