IS230TNTRHIC通用電氣卡件,IS230TNTRHIC說(shuō)明書(shū)文檔
通用模塊安裝說(shuō)明133.35毫米模塊可以安裝在水平或垂直DIN導軌。什么時(shí)候安裝在垂直DIN導軌上的NIU必須位于底部。打開(kāi)牛的門(mén)。串行端口電纜。
留出充足的電源空間裝電線(xiàn)。配有電源的NIU進(jìn)入70mm深的外殼。
額定熱規格基于在5.1cm（2in）以上的間隙上設備下方2.54cm（1in）在NIU模塊的左側。危險場(chǎng)所安裝
?該設備適用于I類(lèi)2類(lèi)，僅限A、B、C、D組或非危險場(chǎng)所。
IS230TNTRHIC通用電氣卡件?警告-爆炸危險-替代部件可能會(huì )影響I類(lèi)分區的適用性
?警告-爆炸危險-處于危險狀態(tài)時(shí)位置，在更換或接線(xiàn)模塊前關(guān)閉電源；
?警告-爆炸危險-請勿連接或除非電源已關(guān)閉，否則斷開(kāi)設備或者已知該區域無(wú)危險。面板安裝為了獲得最佳穩定性，DIN導軌應使用螺釘間距約為5.24cm（6in）。
如果過(guò)度振動(dòng)是一個(gè)因素，則還應擰緊NIU安裝面板。
注：公差為+/-0.13mm（0.005in）非累積。
注：M3.5（#6）應施加1.1-1.4Nm（10-12英寸/磅）的扭矩-32）擰入含有內螺紋和
最小厚度為2.4mm（0.093in）。
General Module Installation Instructions

3
85.85mm
(3.38in)
Modules may be mounted on a
horizontal or vertical DIN rail. When
mounted on a vertical DIN rail, the NIU
must be located at the bottom.
1. Allow sufficient finger clearance for
opening NIU door.
2. Allow adequate clearance for
serial port cables.
3. Allow adequate space for power
wiring.
The NIU with power supply attached fits
into a 70mm deep enclosure.
Rated thermal specifications are based
on a clearance of 5.1cm (2in) above
and below the equipment and 2.54cm
(1in) to the left of the NIU module.
Installation in Hazardous Locations
?
This equipment is suitable for use in CLASS I, DIVISION 2,
GROUPS A, B, C, D or non-hazardous locations only.
?
WARNING - EXPLOSION HAZARD - substitution of
components may impair suitability for CLASS I, DIVISION
2;
?
WARNING - EXPLOSION HAZARD - when in hazardous
locations, turn off power before replacing or wiring modules;
and
?
WARNING - EXPLOSION HAZARD - Do not connect or
disconnect equipment unless power has been switched off
or the area is known to be non-hazardous.
Panel-Mounting
For best stability, the DIN rail should be installed on a panel using
screws spaced approximately 5.24cm (6in) apart.
If excessive vibration is a factor the NIU should also be screwed down to
the mounting panel.
Note: Tolerances are +/- 0.13mm (0.005in) non-cumulative.
Note: 1.1-1.4Nm (10-12 in/lbs) of torque should be applied to M3.5 (#6-
32) steel screw threaded into material containing internal threads and
having a minimum thickness of 2.4mm (0.093in).
