Connecting the device to ground is to quickly release the lightning over-voltage and 
over-current of the device, which is also a necessary measure to protect the body from 
electric shock.

In  different  environments,  the  device  may  be  grounded  differently.  The  following 
will instruct you to connect the device to the ground in two ways, connecting to the 
grounding bar or connecting to the ground via the power cord. Please connect the 
device to ground in the optimum way according to your specific operation environment.

■

If the device is installed in the Equipment Room, where a grounding bar is available, 
you are recommended to connect the device to the Grounding Bar as shown in the 
following figure.
