佈線

This section provides information on wiring the AC 900F controller exclusive of theCI/CM communication interface module. It contains safety instructions, generalguidelines and information on cable routing

本節提供有關 AC 900F 控制器的佈線資訊，但不包括CI/CM 通訊介面模組。它包含安全說明，一般電纜路由指南和資訊

6.1 Safety instructions

安全性說明

The L+ and M terminals are assigned twice. Incorrect wiring may cause shortcircuits and damage the power supply unit or the fuse protection of the power supplyunit. If no suitable protection is provided (suitable module), the CPU module maybe damaged as well. For this reason, the CPU module must be wired in compliancewith the following instructions and an adequately dimensioned fuse must be used

L+ 和 M 終端被分配兩次。不正確的佈線可能導致短路和損壞電源單元或電源的保險絲保護單元。如果沒有提供適當的保護（適當的模組），CPU 模組也可能損壞。因此，CPU 模組必須按照下面的要求接線，必須使用足夠尺寸的保險絲。

6.2 General instructions

通用介紹

Strictly observe the following basic principles and instructions when installing andwiring the controller。

• Keep all connecting lines as short as possible. This is particularly important for the earthing conductors

• 保持所有連線線儘可能短。這對接地導體尤其重要

• Make sure to select sufficiently dimensioned wire cross-sections. This is particularly important for earthing conductors

• 確保選擇足夠尺寸的電線橫截面。這對接地導體尤其重要

• 要實現低阻抗性，即在大表面上的最佳接觸，按以下方式進行：

–establish vibration-resistant connections

建立抗震連線

　　 –use bare contact areas (remove paint, clean surface),

　　 使用裸露接觸區域（去除油漆，清潔表面）

　　 –avoid the use of aluminum parts (oxidize easily)

　　避免使用鋁部件（易氧化）

　　–select solid plug and screw connections

　　選擇實心插頭和螺絲連線

　　–directly earth the cable shields with clips to a well-grounded metallic surface

　　直接接地電纜遮蔽與剪輯到接地良好的金屬表面

　　–do not use drain wires (pig-tails),

　　不要使用接地線（銅辮）？

　　–do not use toothed washers to lock the screw unions

　　不要使用帶齒墊圈來鎖緊螺絲接頭
