Connect Signal Cable - Kaden KS09 Installation Manual

Before performing
electrical work, read
these requirements
1. All wiring must comply with local and national electrical
codes, and must be installed by a licensed electrician.
2. All electrical connections must be made according to the
Electrical Connection Diagram located on the panels of the
indoor and outdoor units.
3. If there is a serious safety issue with the power supply,
stop work immediately. Explain your reasoning to the client,
and refuse to install the unit until the safety issue is
properly resolved.
4. Power voltage should be within 90-100% of rated voltage.
Insufficient power supply can cause malfunction, electrical
shock, or fire.
5. If connecting power to fixed wiring, install a surge protector
and main power switch with a capacity of 1.5 times the
maximum current of the unit.
6. If connecting power to fixed wiring, a switch or circuit
breaker that disconnects all poles and has a contact
separation of at least 1/8in (3mm) must be incorporated
in the fixed wiring. The qualified technician must use an
approved circuit breaker or switch.
7. Only connect the unit to an individual branch circuit outlet.
Do not connect another appliance to that outlet.
8. Make sure to properly ground the air conditioner.
9. Every wire must be firmly connected. Loose wiring can
cause the terminal to overheat, resulting in product
malfunction and possible fire.
10. Do not let wires touch or rest against refrigerant tubing,
the compressor, or any moving parts within the unit.

WARNING
Before performing any electrical or wiring work, turn
off the main power to the system.
Step 6: Connect signal cable
The signal cable enables communication between the indoor
and outdoor units. You must first choose the right cable size
before preparing it for connection.
Cable Types
• Indoor Power Cable (if applicable):
H05VV-F or H05V2V2-F
• Outdoor Power Cable: H07RN-F
• Signal Cable: H07RN-F
Minimum cross-sectional area of
power and signal cables
Rated Current of
Appliance (A)
> 3 and ≤ 6
> 6 and ≤ 10
> 10 and ≤ 16
> 16 and ≤ 25
> 25 and ≤ 32
> 32 and ≤ 40
Choose the right cable size
The size of the power supply cable, signal cable, fuse,
and switch needed is determined by the maximum current
of the unit. The maximum current is indicated on the
nameplate located on the side panel of the unit. Refer to
this nameplate to choose the right cable, fuse, or switch.
