Mounting the Remote I/O Module in the Component Enclosure
If you ordered the remote I/O module with your 9/260 control, it comes
already mounted in the component enclosure. If you have ordered the
remote I/O module separately, use this procedure to mount the remote I/O
module in the component enclosure.
Important: You can not use the remote I/O module in a 9/260 system that
contains either a 9/Series Data Highway Plus communication module or a
9/Series MMS/Ethernet communication module. A 9/260 system can
contain only one Remote I/O, DH+, or MMS/Ethernet module.
ATTENTION: To prevent damage to the module, wear an ESD
wristband while you unpack and install the module. Connect the
wristband to the ground screw on the control’s component
enclosure.
