The units must be mounted, with four screws and in a vertical position, on a 
wall or panel that is made of nonflammable material and is stable enough to 
hold the variable frequency drive’s weight.
On the DC1-…-A6SN version, the main disconnect switch can be locked in 
the OFF position with a standard padlock.
