5 INSTALLATION
You may be electrified if you install/remove a module or connect/disconnect a
cable when power is ON by inadvertently touching a power supply terminal due to
the presence of a high voltage. Also, note that a short circuit or noise may render
the machine defective. To avoid these problems, make sure to turn OFF the
power before install/removing a module or connect/disconnecting a cable.
Static electricity may damage the modules. Remove static electricity from
your body before setting various switches, connecting or disconnecting cables
or connectors.
When insert or remove a module, observe the following precautions to prevent
the module from being damaged:
• Before connecting a module to the mount base connector, check for dirt or
other foreign matters adhered on the terminals.
• When insert/remove a module, ensure that it is vertical to the mount base as
shown below. If you insert/remove a module while it is tilted, the connector
may be damaged.
