HE663909-31828数控模块，ABB使用教程
并非所有外围电缆都配有MVME712M。您可能需要制造或购买某些电缆。到尽量减少辐射，摩托罗拉建议使用屏蔽电缆可能的情况下进行外围连接。MVME761过渡模块安装本节适用于MVME2700的MVME761兼容型号VME模块。安装MVME2700后，请参阅图1-23和按照以下步骤安装MVME761过渡模块：1、将静电带系在手腕上。
HE663909-31828数控模块连接ESD的另一端将皮带系在底盘上作为接地。静电放电带必须固定在在整个过程中，您的手腕和地面。执行操作系统关机。接通交流或直流电源断开并从系统中卸下交流电源线或直流电源线。根据需要卸下机箱或系统盖，以便访问VME模块。
如果MVME2700和MVME761兼容型号被损坏错误地连接到MVME712系列板，而不是纠正MVME761过渡模块。
在通电的情况下插入或拆卸模块可能会导致损坏至模块组件。在这种情况下，存在可能导致死亡的危险电压设备搬运、测试和调整时要格外小心。
机箱的前部或后部。（您可能需要将其他模块移入机箱为MVME761的布线留出空间。）4.将P2适配器板连接到插槽处的P2背板连接器被MVME2700 VME模块占用。图1-24。MVME761/MVME2700电缆连接5.将配备MVME761的64芯电缆从P2适配器板上的J3到过渡模块上的P2。确保用连接器针脚1.6定位电缆针脚1。用提供的螺钉将MVME761固定在机箱中，与横向安装轨道接触良好，以将射频发射。
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.
