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 screw.
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. Screws for attaching are not provided.
Please use the proper screws.
4.2 Mounting the capacitor
(
MRS20
Single-phase models and
MRS18/MRS16
and
MRW18
single-phase models with alarm circuits.)
Before mounting the capacitor, check to see that the capacitance of the capacitor provided,
matches the capacitance indicated on the fan's nameplate.
Use M4 screw (not provided) to mount the capacitor.
Note : Tighten the capacitor mounting screw with a torque of 1 N
･
m(141.61oz-in)
or less in order to prevent damaging the mounting leg.
4.3 Mounting the capacitor cap
(
MRS20
Single-phase models and
MRS18/MRS16
and
MRW18
single-phase models with alarm circuits.)
Use the capacitor cap provided for insulation of the capacitor terminal connections.
①
Pass the lead wires through the capacitor cap as shown in figure.
②
Connect the lead wires to the terminals or use terminal ends.
③
Cap the capacitor with the capacitor cap.
4.4 Capacitor Connection
(case of 4-terminal type :
MRW18
type)
The capacitor internal wiring is as follows:
Capacitor terminals are internally electrically connected in twos;
A-B and C-D for easy connection.
For easy to install terminals use #187 series AMP terminals.
For lead wire connection, use one lead wire for each individual terminal.
