[Selecting Non-Fuse Breaker (Nf) Or Ground Fault Circuit Interrupter (Gfci)]; Connecting Remote Controller, Ahu Controller, And Outdoor Unit Transmission Cables - Mitsubishi Electric CITY MULTI PAC-AH001-1 Installation Manual

[Selecting non-fuse breaker (NF) or ground fault circuit interrupter (GFCI)]

To select NF instead of a combination of Class B fuse with switch, use the following:
• In the case of Class B fuse rated 15 A or 20 A,
NF model name (MITSUBISHI): NF30-CS (15 A) (20 A)
Use a GFCI with a sensitivity of less than 30 mA 0.1 s.
CAUTION
Do not use anything other than the correct capacity breaker and fuse. Using fuse, wire or
copper wire with too large capacity may cause a risk of malfunction or fire.
7.2 Connecting remote controller, AHU controller, and outdoor unit
transmission cables
The AHU controller can be installed to operate using either a Mitsubishi remote controller or a 3rd party
controller. The AHU controller cannot be operated by a Mitsubishi remote controller and a 3rd party
controller at the same time.
NOTE
Ensure that the wiring is not pinched when fitting the terminal box cover. Pinching the
wiring may cut it.
CAUTION
Install wiring so that it is not tight and under tension. Wiring under tension may break, or
overheat and burn.
• Fix power source wiring to control box by using buffer bushing for tensile force. Connect transmission
wiring to transmission terminal block through the hole of control box using bushing.
• After wiring is complete, make sure again that there is no slack on the connections, and attach the cover
onto the control box in the reverse order removal.
CAUTION
Wire the power supply so that no tension is imparted. Otherwise disconnection, heating or
fire result.
Specifications are subject to change without notice.
