<Example of "F2" calculation>
*Condition PEFY-NMSU × 4 + PEFY-NMAU × 1, C = 8 (refer to right sample chart)
F2 = 18.6 × 4/8 + 38 × 1/8
= 14.05
→
16A breaker (Tripping current = 8 × 16A at 0.01s)
*3 Current sensitivity is calculated using the following formula.
G1 = V2 × (Quantity of Type1) + V2 × (Quantity of Type2) + V2 × (Quantity of Type3) + V2 × (Quantity of Others)
+ V3 × (Wire length[km])

6.4. Connecting remote controller, indoor and
outdoor transmission cables (Fig. 6-3)
• Connect indoor unit TB5 and outdoor unit TB3. (Non-polarized 2-wire) The “S”
on indoor unit TB5 is a shielding wire connection. For specifications about the
connecting cables, refer to the outdoor unit installation manual.
• Install a remote controller following the manual supplied with the remote
controller.
• Connect the remote controller’s transmission cable within 10 m, 33 ft using a
0.75 mm
2
(AWG22) core cable. If the distance is more than 10 m, 33 ft, use a
1.25 mm
2
(AWG16) junction cable.
1
MA Remote controller
• Connect the “1” and “2” on indoor unit TB15 to a MA remote controller. (Non-
polarized 2-wire)
• DC 9 to 13 V between 1 and 2 (MA remote controller)
2
M-NET Remote controller
• Connect the “M1” and “M2” on indoor unit TB5 to a M-NET remote controller.
(Nonpolarized 2-wire)
• DC 24 to 30 V between M1 and M2 (M-NET remote controller)
3
Wireless remote controller(When installing wireless signal receiver)
• Connect the wire of wireless signal receiver (9-pole cable) to CN90 of indoor
con-troller board.
• When more than two units are run under group control using wireless remote
controller, connect TB15 each with the same number.
• To change Pair No. setting, refer to installation manual attached to wireless re-
mote controller. (In the default setting of indoor unit and wireless remote control-
ler, Pair No. is 0.)
