NOTES
• Use ring-type crimp style terminal for connections to the
power terminal block. (
Refer to Fig. 6 )
Also, insulate the crimped area by attaching an insula-
tion sleeve, etc.
If these are not available, see the following section.
(a) Wiring of different thicknesses cannot be connected
to the power terminal block.
(A loose connection could cause abnormal heating.)
(b) When connecting wire of the same diameter, make
the connection as shown in the figure 7.
• Use an appropriate screwdriver for tightening the termi-
nal screw.
Using a screwdriver that is too small could damage the
screw head and prevent proper tightening.
• Over tightening the terminal screw could damage the
screw.
Refer to the Table 4 for the terminal screw tightening
torque.
• When fastening the wire, use the included clamp 2)-1
so as not to apply tensile force to the wire connection and then securely fasten the wire. Also, after wiring
is completed, organize the wiring so that the Electrical Components Box lid does not pop up and then prop-
erly replace the Electrical Components Box lid.
Make sure no wires are pinched when replacing the Electrical Components Box lid.
Always use the wire through hole to protect the wires.
• Do not pass the transmission wiring and power supply wiring through the same locations and outside of the
unit keep them separated by at least 2 in..
Not doing so could cause the transmission wiring to pick up electric noise (external noise) and result in a
malfunction or breakdown.
• After the wiring working is complete, use sealer (field supply) to seal closed the wire through hole.
(Entry by small animals, etc., could cause a malfunction.)
8. INITIAL SETTING
• When the refrigerant piping and wire installation work is completed, make the following settings as required.
1. Setting for when connecting the COOL/HEAT SELECTOR to the BS unit.
〈
Setting description
〉
Set the input signal from the COOL/HEAT SELECTOR (sold separately) to ON/OFF.
〈
Setting method
〉
Set the dip switches (DS1-1) on PCB (A1P) as shown at left before turning on the power to the BS unit.
NOTES
This setting is read by the microcomputer when the BS unit power is turned on.
• Be sure to make the setting before turning on the power.
• Always close the Electrical Components Box lid after making the setting.
2. Setting when changing the “Automatic mode differential” in the Cooling/Heating Automatic Oper-
ation Mode.
