Precautions for Safe Use
• Do not drop any Unit or subject it to abnormal vibration or shock. Doing so may result in Unit malfunc-
tion or burning.
• When transporting any Unit, use the special packing box for it. Also, do not subject the Unit to exces-
sive vibration or shock during transportation.
• Mount terminal blocks and connectors only after checking the mounting location carefully. Be sure
that the terminal blocks, expansion cables, and other items with locking devices are properly locked
into place.
• Do not apply labels or tape to the Units. When the Unit is installed or removed, adhesive or scraps
may adhere to the pins in the NX bus connector, which may result in malfunctions.
• Do not touch the pins in the NX bus connector on the Unit. Dirt may adhere to the pins in the NX bus
connector, which may result in malfunctions.
