Warning / 警告
Do not connect the product to the power
supply via a wall switch.
The shortage of the switch capacity could
cause fire.
請勿通過牆壁開關連接電源。
開關容量不足可能引起火災。
Securely connect the earth and install an
earth leakage circuit breaker.
Failure to do so could cause a malfunction
or an electric shock due to an electrical fault.
請牢固接地並安裝接地漏電斷路器。
否則可能會因電氣故障而造成故障或觸電。
Use a 220 V AC single-phase power supply.
Using a power supply other than 220 V AC
single-phase may cause fire or electric shock.
使用220 V AC單相電源。
使用220 V AC單相電源以外的電源可能造成
火災或觸電。
Electrical work and main unit installation
must be performed safely and reliably
by qualified personnel certified by the
Electrical and Mechanical Services
Department (EMSD).
Incorrect electrical work or installation work
may cause electric shock, fire, or the unit
falling down.
電氣作業及主機安裝必須由符合資質的機電工
程署(EMSD)認證人員以安全可靠的方式執行。
不當電氣作業或安裝作業可能造成觸電、火
災或裝置墜落。
Securely connect the power cable.
An insecure connection may result in
overheating of the connectors and cause fire.
牢固連接電源線。
連接不牢可能導致連接器過熱並引起火災。
Caution / 注意
Earth leakage circuit breaker (leakage
current not exceeding 30 mA) and circuit
breaker shall be directly connected to
the supply terminals and shall have a
contact separetion in all poles, providing
full disconnection under overvoltage
category III conditions (Secure at least 3
mm between contact points). Use a circuit
breaker for 16 A or greater.
接地漏電斷路器（漏電流不超過30 mA）和斷
路器應直接連接至電源終端，並在所有電極上
都設有接觸隔離，確保在III類過電壓下完全斷
開連接(接觸點之間至少留出3mm距離才能保
證安全)。使用16 A或以上斷路器。

2. Connect the power cable to the "terminal
block for power supply".
2. 將電源線連接到「電源接線盒」 。
(1) Peel off around 60 mm of the outer sheath of the power cable.
(2) Make the power line 50 mm.
(3) Peel off 12 mm of the sheath at the end of the cable.
(4) Secure the power cable firmly (VVF cable: ø2 mm) to the
"terminal block for power supply" of the main unit with screws.
(5) Secure the power cable with a cable clip.
(1) 將電源線外皮剝去約60 mm。
(2) 將電源線長度做成50 mm。
(3) 將電纜末端皮剝去12 mm。
(4) 用螺絲將電源線(VVF電纜：ø2 mm)牢牢固定在主機
的「電源接線盒」上。
(5) 用電纜夾固定電源線。
