IS230TNTRHIC通用电气卡件,IS230TNTRHIC说明书文档
通用模块安装说明133.35毫米模块可以安装在水平或垂直DIN导轨。什么时候安装在垂直DIN导轨上的NIU必须位于底部。打开牛的门。串行端口电缆。
留出充足的电源空间装电线。配有电源的NIU进入70mm深的外壳。
额定热规格基于在5.1cm（2in）以上的间隙上设备下方2.54cm（1in）在NIU模块的左侧。危险场所安装
•该设备适用于I类2类，仅限A、B、C、D组或非危险场所。
IS230TNTRHIC通用电气卡件•警告-爆炸危险-替代部件可能会影响I类分区的适用性
•警告-爆炸危险-处于危险状态时位置，在更换或接线模块前关闭电源；
•警告-爆炸危险-请勿连接或除非电源已关闭，否则断开设备或者已知该区域无危险。面板安装为了获得最佳稳定性，DIN导轨应使用螺钉间距约为5.24cm（6in）。
如果过度振动是一个因素，则还应拧紧NIU安装面板。
注：公差为+/-0.13mm（0.005in）非累积。
注：M3.5（#6）应施加1.1-1.4Nm（10-12英寸/磅）的扭矩-32）拧入含有内螺纹和
最小厚度为2.4mm（0.093in）。
General Module Installation Instructions

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).
