function or burning.
• When transporting any Unit, use the special packing box for it. Also, do not subject the Unit to ex-
cessive vibration or shock during transportation.
Mounting
• Always turn OFF the power supply before mounting a Unit. If the power supply is not OFF, the Unit

that the terminal blocks, expansion cables, and other items with locking devices are properly locked
into place.
