Notes:

1、It is better to fasten the bolts again thoroughly every 10 minutes after screwing down them.

2、Screwing down the bolts of the box should strictly act

according to “installation instruction”

3、please check whether the pothook connector has been installed or not before screwing down the box for aerial application
