Internal fan mounting plate
3-4 When Adjustable Louver is used Standard type Lateral mounting only
Attaching the Adjustable Louver enables to direct output air to a desired direction.
*Cooling capacity may decrease by as much as 5% when the louver is used.
*To keep the set angle not to be affected by eternal impact including vibration,
the base plate and the louver top is rather tightly fitted.
When straight wind is desired, use the base plate only.
The head of base plate will protrude from the fan mounting plate surface by 4 mm.
When angled wind is desired, attach the louver top on the base plate and adjust direction by turning the louver top.
Louver blades are angled at 5 degrees. The locking system of louver top works at every 45 degrees. Pay attention
that short circuit described
☞ See
page 35 can occur depending on the louver position.
The head of louver top will protrude from the fan mounting plate surface by 7 mm.
4. Wiring
Caution
Please observe all the related regulations of your country in installing and wiring COOLCABI.
Supply voltage should be as specified on the rating plate.
Allowable power fluctuation in operation is b5% and - % of the rated voltage. It means only
instantaneous voltage fluctuation is allowed and does not mean that any voltage within this range can be
constantly supplied.
Be sure to install an earth leakage breaker exclusively for COOLCABI. As a guide of selection, a sensitivity
current of 3 mA or around is recommended.
→ ailure to this can cause tripping of the earth leakage breaker for the enclosure in case of electric
leakage.
Make sure that grounding has been properly done.
Starting current is applied for about one second when the power is connected to COOLCABI or when
COOLCABI starts cooling operation.
Selection of a circuit breaker should be made so as to assure stable operation not affected by such starting
current as well as providing effective protection against overcurrent.

Before connecting power, make sure that there is no problem with the supply voltage, wiring and ground
connection.
In wiring works, the possibilities of contacting with sharp edges, corroding of terminals, aging of materials
and impact by vibration should be considered.
4- Wiring
Process the cable ends.
Stranded wire: AW 4 to , . mm to 4mm Strip length 7mm
Rod terminal: . 5mm to 4mm
errule terminal: . 5mm to 4mm
Remove the terminal cover
all prevention screw is used for Roof mounting models .
3 Put a cable though the hole in the terminal cover and insert it into
the cable entry port of the terminal block. Use the
knockout hole s provided in the terminal cover as necessary.
4 Tighten the screw with a flat-head screw driver to secure the wire.
