Installation and removal of dustproof cover

When the QCPU-A is used, the dustproof cover supplied with the main
base unit must be installed to the I/O module loaded on the right hand
side of the QCPU-A to prevent the ingress of foreign matter into the I/O
module.
Always install the dustproof cover. Without the dustproof cover, foreign
matter will enter the I/O module, causing a failure.
How to install and remove the dustproof cover will be described below.
(1) Installation of dustproof cover
To insert the dustproof cover into the I/O module, insert it into the
connector or terminal side slit first as shown above. Then push the
opposite side of the dustproof cover into the I/O module to
complete installation.
