配電室內(nèi)安裝變極器-中英
如果你在同一配電柜中安裝兩個或者更多變極器，請注意以下事項(xiàng)
•確保一個變極器的左邊和另一變極器的右邊之間至少有5分米的距離。
•如果將變極器水平排列而未留出任何間距（一個緊挨一個安裝），去除變極器頂部的通風(fēng)密封，并在40℃或40℃以下溫度中操作（3.7 kW模式或更低），或50℃（5.5 kW模式或更高）。
•確保分別在變極器的頂部和底部至少留出20分米的空間。
•安裝一個空氣偏移板，以確保熱量從變極器底部上升的時候不會影響到其頂部。

禁止拆卸 •不允許拆卸，修改或修理。這樣做會導(dǎo)致電擊，火災(zāi)和人身傷害。需要修理時，請與您的銷售代理處聯(lián)系。
被禁止的 •切勿在設(shè)備運(yùn)行時將手指伸入其中，例如：電纜接線孔和冷卻風(fēng)扇蓋。這樣做會導(dǎo)致電擊或人身傷害。
•請勿將任何種類的物體放置或插入變極器內(nèi)。這樣會導(dǎo)致電擊或火災(zāi)。
•請勿讓變極器與水或任何其他液體接觸。那樣會導(dǎo)致電擊或火災(zāi)。
警告
被禁止的 •當(dāng)運(yùn)輸或搬動時，不要用前面板支撐。
將蓋子可能會落下，而且裝置會滑落導(dǎo)致意外傷害。
2.1 接線警告
危險(xiǎn)
被禁止的 •當(dāng)接通電源時，請勿移開前蓋或打開關(guān)在配電柜內(nèi)的門。本裝置包括許多高壓部件且與這些部件接觸會導(dǎo)致電擊。強(qiáng)制性的 •在裝上前蓋后接通電源或關(guān)閉配電柜內(nèi)的門。如果在未安裝前蓋或未關(guān)閉配電柜內(nèi)的門的情況下接通電源，會導(dǎo)致電機(jī)或其他傷害。
•電器施工工作必須由合格的專家完成。
由不具備專業(yè)只是的人員完成輸入電流的連接可能會導(dǎo)致火災(zāi)或電擊。
•正確連接輸出端（電機(jī)的側(cè)面）。
如果相位序列不正確，電機(jī)將反相運(yùn)行，容易導(dǎo)致人身傷害。
•在安裝完成之后接線。
如果在安裝完成之前接線可能會導(dǎo)致傷害或電擊。
•在接線前，按照以下步驟執(zhí)行。
（1）關(guān)閉輸入電源
（2）至少等待10分鐘并檢查確保充電指示燈不再發(fā)亮。
（3）使用能夠測量直流電壓（800 VDC或更大）的檢測器，同時，檢查并確保與直流主電路接通的電壓為45V或更小。
如果沒有按照以上步驟正確執(zhí)行，接線將引起電擊。
•按指定的扭矩?cái)Q緊接線端子板上的螺絲。
如果沒有按指定的扭矩?cái)Q緊螺絲，可能會導(dǎo)致火災(zāi)。
危險(xiǎn)
接地 •必須安全接地。
如果沒有安全接地，出現(xiàn)故障或泄露時就可能會導(dǎo)致電擊或火災(zāi)。
警告
被禁止的 •切勿將帶有內(nèi)裝式電容器（例如：降干擾過濾器或電泳吸收器）的裝置安裝至輸出（電擊側(cè)面）終端。
這樣可能會導(dǎo)致火災(zāi)。
■ 防止無線電干擾
為了防止電器干擾，如：無線電干擾，使用分開的束線連接至主電路的電源終端（R/L1，S/L2，T/L3）以及將電線接至電機(jī)終端（U/T1，V/T2，W/T3）。
■ 控制和主電源
VFS9的控制電源和主電路電源是相同的。
如果故障或跳閘導(dǎo)致主電路不得不關(guān)閉，控制電源也將被關(guān)閉。當(dāng)檢查故障或跳閘的原因時，使用跳閘保持選擇參數(shù)。
接線
•由于主電路終端之間的間隙很小，使用有套的壓力終端進(jìn)行連接。連接終端以便臨近的終端不會互相碰觸。
•對于接地終端 使用與表10.1中給出的大小相同或比其更大尺寸的電線，并始終將變極器接地（200V電壓等級：D型接地[以前的接地類型是3]；400V電壓等級：C型接地[以前的接地類型是3]）。
使用盡可能使用粗而端的接地線，且盡量靠近變極器接線。
•有關(guān)電線尺寸請參看表9-1.
•在表10-1中列出的主電路線路的長度應(yīng)該不應(yīng)長于30米。如果電線超過30米，電線的尺寸（直徑）必須增加。

2.2 標(biāo)準(zhǔn)連接
危險(xiǎn)
被禁止的 •切勿將輸入電源連接到輸出終端（U/T1，V/T2，W/T3）。將輸入電源連接至輸出終端可能會導(dǎo)致變極器發(fā)生火災(zāi)。
•請勿將電阻器連接至直流電終端（通過PA-PC或通過PO-PC）。
這樣可能會導(dǎo)致火災(zāi)。
按照操作說明書的“獨(dú)立制動電阻”章節(jié)中的指導(dǎo)連接電阻器。
•第一次關(guān)閉輸入電源時，在至少等待10分鐘之后方可觸摸設(shè)備（MCCB）上與變極器電源側(cè)面相連接的電線。
在此規(guī)定時間以前觸摸電線可能會導(dǎo)致電擊。
始終接地 •使用接地線安全連接。
如果沒有進(jìn)行安全的接地連接，出現(xiàn)故障或泄露時就可能會導(dǎo)致電擊或火災(zāi)。
I Installing more than one unit in a cabinet
II you are Installing two or more inverters in one cabinet, pay attention to Ihe folloing.
• Ensure a space of at least 5 centimeters on the left and right sides of the inverters.
• If the inverters are horizontally arranged with no space between them (side-by-side installation), re¬move the ventilation seals on top of the inverters and operate at 40°C or less (model ot 3.7kW or less) or 5CTC (model ol 5.5kW or more).
• Ensure a space ot at least 20 centimeters on the top and bottom of the inverters.
• Install an air deflecting plate so that the heat rising up from the inverter on the bottom does not affect the

result in electric shock or other Injury. • Electrical construction work must be done by a qualified expert. Connection of input power by someone who does not have that expert knowledge may result in fire or electric shock. • Connect output terminals (motor side) correctly. If the phase sequence is incorrect, the motor will operate in reverse and that may result in injury. • Wiring must be done after installation. If wiring is done prior to installation that may result in injury or electric shock • The following steps must be performed before wiring. (1) Shut off all input power. (2) Wait at least ten minutes and check to make sure that the charge lamp is no longer lit. (3) Use a tester that can measure DC voltage (800VDC or more), and check to make sure that the voltage to the DC mam circuits (across PA-PC) is 45V or lass. If these steps are not properly performed, the wiring will cause electric shock. . Tighten the screws on the terminal board to specified torque. If the screws are not tightened to the specified torque, it mav lead to fire.

I Preventing radio noise
To prevent electrical interference such as radio noise, separately bundle wires to the main circuit's power terminals (R/L1, S/L2. T/L3) and wires to the motor terminals (U/T1, V/T2, W/T3).
I Control and main power supply
The control power supply and the main circuit power supply lor the VF59 are the same.
If a malfunction or trip causes the main circuit to be shut off. control power will also be shut off. When Checking ihe cause of the malfunction or ihe trip, use the trip holding retention selection parameter.
I Wiring
• Because the space between the main circuit terminals is small use sleeved pressure terminals for the connections. Connect trie terminals so that adjacent terminals do not touch each other.
• For ground terminal i use wires of the size that is equivalent to or larger than those given in table 10 1 and always ground the inverter (200V voltage class. D type ground [former type 3 ground]; 400V class: C type ground [former special type 3 ground)).
Use as large and short a ground wire as possible and wire it as close as possible to the inverter.
• See Ihe table in 9-1 for wire sizes.
• The length of the main circuit wire In 10-1 should be no longer than 30 meters. If the wire Is longer than 30 meters, trie wire size (diameter) must bi

2.2 Standard connections
Danger
Prohibited • Do not connect input power to the output (motor side) terminals (UTl . V/T2, W/T3). Connecting input power to the output could destroy the inverter or cause a lire. • Do not connect resistors to DC terminals (across PA-PC or across PO-PC). It could cause a fire. Connect resistors as directed in the instructions for "Installing separate braking resistors.' • First shut oft input power and wait at least 10 minutes before touching wires on equipment (MCCB) that is connected to inverter power side. Touchinq the wires before that time could result in electric shock.
Always connect to ground • Securely connect to ground with a ground wire. If a secure connection to ground is not made, this could cause electric shock or (ire when a malfunction or leak current occurs.
