Installing NX Units
This section describes how to mount two NX Units to each other.
Always turn OFF the power supply before you mount NX Units.
Always mount NX Units one at a time. If you attempt to mount multiple NX Units that are already con-
nected together, the connections between the NX Units may separate from each other and fall.
Precautions for Safe Use
• Do not apply labels or tape to the Unit. 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.
