MNS低压抽屉柜框架为组合式结构，基本骨架由C型钢材组装而成;MNS型组合式低压开关柜的每一个柜体分隔为三个室，即水平母线室(在柜后部)，抽屉小室(在柜前部)，电缆室(在柜下部或柜前右边)。其操作步骤为：
The frame of MNS low-voltage drawer cabinet is a combined structure, and the basic framework is assembled from C-shaped steel; Each cabinet body of MNS type combined low-voltage switchgear is divided into three rooms, namely, horizontal bus room (at the rear of the cabinet), drawer room (at the front of the cabinet), and cable room (at the bottom of the cabinet or at the right of the front of the cabinet). The operation steps are:
a：在远程、就地旋纽旁边的有一小孔(右下方)，用小螺丝刀伸进小孔向下压挡板。
a: There is a small hole (lower right) beside the remote and local buttons. Use a small screwdriver to reach into the small hole and press down the baffle.
b：在一次关左侧有一小孔，同样用另一小螺丝刀伸进去顶开。
b: There is a small hole on the left side of the door at one time, and another small screwdriver is also used to push it in and open it.
c：两螺丝刀同时用力解锁，打开抽屉门。
c: Unlock the drawer door with two screwdrivers at the same time.
d：手动调整一次开关前面连杆(有时往往打不开，就是因为该处连杆卡住)断开主开关。
d: Manually adjust the front connecting rod of the primary switch (sometimes it can't be opened because the connecting rod is stuck) to disconnect the main switch.
e：再确认主开关下方的机械连杆是否已释放到位，若没到位，活动一下即可。
e: Then confirm whether the mechanical linkage under the main switch has been released in place. If not, move it.
f：旋开二次开关按钮，抽出位置
f: Release the secondary switch button to the safe withdrawal position
g：抽出抽屉，然后复位，恢复送电。
g: Pull out the drawer, then reset it and resume power supply.
h：只有一次开关与二次开关啮合到位抽屉才能抽拉自如、开关才能旋转流畅。
h: Only when the primary switch and the secondary switch are engaged in place can the drawer be pulled freely and the switch can rotate smoothly.
MNS low-voltage drawer cabinet has the advantages of simple interlocking mechanism, safety and reliability, and flexible drawer exchange. If you have any needs or doubts, please come to our website http://www.tongyuhengcheng.com Consult and understand!
