The push-in length have to be additionally considered for each connector as mentioned below.如不正确安装，将不能达到指定IP 防水防尘等级1. 使用PMACUT 剪切工具剪切软管，剪切面与软管轴心垂直Straight cut with PMA Cutting tool PMACUT, 90o to the conduit axis. 2. 管卡已预先安装，推入时轻微转动直至不能推入为止。
The retaining clip is pre-mounted. Push in with a slight twist until the stop. 3. 轻微回拉软管，确保锁紧Pull back slightly to ensure the locking mechanism is fully engaged. 4. 在振动或相似情况下的应用建议：为保护螺纹最好使用密封胶或黏合剂如：Loctite） Recommendation for applications under vibrations or similar: Protect threads with commercial adhesive or seal compound (e.g. Loctite). 5. 安装管接头的软管部分不要弯曲，如果定位请使用管夹或其他支撑Do not bend off the PMAFLEX conduit directly after the connector. If necessary destine the direction with a system support or similar. 6. 为安全起见： 需用螺丝刀才能开启管夹。

如果密封套没有完全安装好，管卡将不能安装） Push conduit with seal cap with slight twist fully into connector. (For safety reasons, retaining clip will not fit if seal cap is not fully installed.) 6. 推进管卡直至完全配合确保管卡缺口部位在软管侧） Push in the Retaining Oval Clip until the barbed hooks are optimal set. (Ensure that the opening slot of the retaining clip is on conduit side) 7. 在振动或相似情况下的应用建议：为保护螺纹最好使用密封胶或黏合剂如：Loctite） Recommendation for applications under vibrations or similar: Protect threads with commercial adhesive or seal compound (e.g. Loctite). 8. 安装接头的软管部分不要弯曲， 如果定位请使用管夹或其他支撑。
