5.2.8 Installing Rack-to-Rack I/O Cables
1) Connecting the cable
Caution When connecting the Rack-to-rack I/O cables to the Motion Module, turn OFF the power sup-
ply to all Power Supply Modules.
Connecting the cables while the power is being supplied to the Power Supply Module
may damage the Module or cause a malfunction of the GL120 and GL130.
Caution The total length of the rack-to-rack I/O cable for each station is always 6.0 m or less.
If the total length of the cables exceeds 6.0 m, operational errors may occur at the station.
Caution Make sure that all cable connectors for the Module are securely inserted and tightened.
Insufficient insertion and/or looseness may cause malfunction of the GL120 and GL130.
Rack-to-rack I/O Cables are used to connect Expander Modules mounted on adjacent
Racks. This section describes how to connect Rack-to-rack I/O Cables towards the Expander
Module.
1) Remove the cover from the Expander Module, then install the Expander Module on the
Mounting Base.
