4. ELECTRIC WIRING / 電氣工程
(1) Before carry out any electrical work, switch off at mains.
Use double-coated cable of 6.0 mm²
Lead the Power Cable from the indoor power board and
install the Miniature Circuit Breaker outside the bathroom.
(2) Make the wiring to the Unit as following (2a) or (2b)
(2a) Break the fitting rubber attached to the case side and
pass the cable through it.
(2b) Lead the cable from the back of the Back Plate.
Unscrew the cord holder and fix the cable. Strip the
cable (coating) ends and fasten them to the ELB (L,N)
with 1 N•m torque.
(3) Connect wires in correct polarity (L, N)
Connect the wires in wrong polarity (L, N) causes an abnormal
condition which may lead to leaking, burning, etc.
Before wiring, please check polarity (L, N) with voltage range
of a tester or voltmeter by connecting one terminal of the meter
to earth while the other to one of the Power Supply terminals.
When the needle of the meter deflects greatly, the polarity of
the Power Supply terminal is 'L'.
(4) The unit must be earthed. Earth Rod handling procedure.
Select a adapter place to bury the optional Earth Rod (DQ-6H)
The Earth Rod should be buried 70cm at least into the
ground surface.
Make sure that the ground resistance is less than 100Ω
If the ground resistance is not less than 100Ω, drive the
rod deeper into ground surface or use 2 or 3 rods.
(1) 在展開電氣工程前,須確保主要電源經已關閉。
應使用氯乙烯樹脂雙層包覆式 6.0mm²以上。
由室內配線板,而在浴室外面設置電流回路斷開器。
(2) •
對裝置聯結接線時,布線法有兩種,見下面。
(2a) 對或 (2b)。
(2a) 撕開里板側面的橡膠配件,對它串通電纜和端子速接。
(2b) 將電纜由里板的背面連接裝置機身上。
電源供應線應根據如圖所示的長度割除。
打開電線柄然後安好電線。剝下電線的包皮後,以1N•m
的轉矩擰緊ELB (L, N)。
(3) 佈置電線時,可要精確連接極性(L,N)
" 佈置電線時,可要精確連接極性(L,N) "極性(L,N)可
要精確連接,免得機器萬一有毛病時,在未開動條件下發生反
常接通現象,會使到漏電、燒傷等事故發生,多加留意。
極性(L,N)的簡易測驗法。請在佈線預前,必須確認極性
(L,N),再要精確連接於機身。可用電壓測距(range)或
電壓計來測定,先將測定機的一邊端子連接於地線,再使另一
端子接觸到電壓端子。
此時,見到試器的指針振幅較大,其電源端子的極性是L,便將
它連接於機身記號的接點。
(4) 裝置上必須連結地線。接地線割除操作次序。
接地棒(DQ-6H)選擇較濕潤的地點打進為要。
接地棒要打進 土面70公分深度以上。
必須測定檢查接地電阻是否為100Ω(歐姆)以下
如果接地電阻不致100Ω以下時,應要更行打深,
或需要多打進2至3條接地棒。
