HE663909-31828數(shù)控模塊，ABB使用教程
并非所有外圍電纜都配有MVME712M。您可能需要制造或購買某些電纜。到盡量減少輻射，摩托羅拉建議使用屏蔽電纜可能的情況下進(jìn)行外圍連接。MVME761過渡模塊安裝本節(jié)適用于MVME2700的MVME761兼容型號VME模塊。安裝MVME2700后，請參閱圖1-23和按照以下步驟安裝MVME761過渡模塊：1、將靜電帶系在手腕上。
HE663909-31828數(shù)控模塊連接ESD的另一端將皮帶系在底盤上作為接地。靜電放電帶必須固定在在整個過程中，您的手腕和地面。執(zhí)行操作系統(tǒng)關(guān)機。接通交流或直流電源斷開并從系統(tǒng)中卸下交流電源線或直流電源線。根據(jù)需要卸下機箱或系統(tǒng)蓋，以便訪問VME模塊。
如果MVME2700和MVME761兼容型號被損壞錯誤地連接到MVME712系列板，而不是糾正MVME761過渡模塊。
在通電的情況下插入或拆卸模塊可能會導(dǎo)致?lián)p壞至模塊組件。在這種情況下，存在可能導(dǎo)致死亡的危險電壓設(shè)備搬運、測試和調(diào)整時要格外小心。
機箱的前部或后部。（您可能需要將其他模塊移入機箱為MVME761的布線留出空間。）4.將P2適配器板連接到插槽處的P2背板連接器被MVME2700 VME模塊占用。圖1-24。MVME761/MVME2700電纜連接5.將配備MVME761的64芯電纜從P2適配器板上的J3到過渡模塊上的P2。確保用連接器針腳1.6定位電纜針腳1。用提供的螺釘將MVME761固定在機箱中，與橫向安裝軌道接觸良好，以將射頻發(fā)射。
Not all peripheral cables are provided with the MVME712M.
You may need to fabricate or purchase certain cables. To
minimize radiation, Motorola recommends shielded cable for
peripheral connections where possible.MVME761 Transition Module Installation
This section applies to MVME761-compatible models of the MVME2700
VME module. With the MVME2700 installed, refer to Figure 1-23 and
proceed as follows to install an MVME761 transition module:
1. Attach an ESD strap to your wrist. Attach the other end of the ESD
strap to the chassis as a ground. The ESD strap must be secured to
your wrist and to ground throughout the procedure.
2. Perform an operating system shutdown. Turn the AC or DC power
off and remove the AC cord or DC power lines from the system.
Remove chassis or system cover(s) as necessary for access to the
VME modules.
!
Caution
The MVME2700, MVME761-compatible models, will be damaged if it is
mistakenly connected to the MVME712 family of boards instead of the
correct MVME761 transition modules.
!
Caution
Inserting or removing modules with power applied may result in damage
to module components.
!
Warning
Dangerous voltages, capable of causing death, are present in this
equipment. Use extreme caution when handling, testing, and adjusting.
3. Remove the filler panel(s) from the appropriate card slot(s) at the
front or rear of the chassis. (You may need to shift other modules in
the chassis to allow space for the cabling to the MVME761.)
4. Attach the P2 adapter board to the P2 backplane connector at the slot
occupied by the MVME2700 VME module.Figure 1-24. MVME761/MVME2700 Cable Connections
5. Route the 64-conductor cable furnished with the MVME761 from
J3 on the P2 adapter board to P2 on the transition module. Be sure
to orient cable pin 1 with connector pin 1.6. Secure the MVME761 in the chassis with the screws provided,
making good contact with the transverse mounting rails to minimize
RF emissions.
