Checking after Installation
Before electrically starting up the switch, perform the following checkups after the
switch is installed:
(41) If the switch is installed on the cabinet, check whether the installation point
between the cabinet and the switch is strong. If the switch is installed on the
desk, check whether there is enough space for the switch to discharge its heat
and whether the desk is stable.
(42) Check whether the connected power meets the power requirements of the
switch.
(43) Check whether the grounding line is correctly connected.
