1
Remove the expansion protective cover from the IG-1000 (main unit).
2
Install the amplifiers (expansion units) on the DIN rail.
Refer to "DIN rail mount type (Main unit)" for details about how to mount.
3
Push the expansion unit into the main unit connector until a clicking
sound can be heard.
The expansion unit additionally installed next to the main unit is referred to as
expansion unit 1. Subsequent expansion units are referred to as expansion unit 2,
expansion unit 3, etc.
4
Install the end units (OP-26751: 2 units in a set) (sold separately) on both
sides of the amplifiers (main and expansion units). Secure the end units in
place with screws on top (2 on each end unit).
The end units are mounted in the same way as the amplifiers.
Note Fix the amplifiers securely using the end units (OP-26751: 2 units
in a set) (sold separately) or commercially available DIN rail fixing
tool to prevent the amplifiers from slipping the DIN rail or coming
off from the DIN rail due to machine vibration.
