Installation

 

It is advisable to choose an easy to operate and observe site of the highway level room and install the Control Panel on the wall by 4 ￠8x50mm expansion bolts , where is 1500mm above the ground. See the dimension indicated in the Legend 1.

 

Notes: Follow the electric interlocking construction specifications, pass the post-protection cable through the ￠60 protective tube under the Control Panel; Fasten the skin of the cable on the bolts next to the protective tube orifice; Pour into insulation paste after cable is distributed as same as the Legend.

 

Follow the electric interlocking construction specifications, clean and fasten the both the inside and outside the Control Panel while a power test is a must; lock the Control Panel after all the buttons and indictor lights are tested.
