Uninterruptible power supply output of the neutral line (N pole), must be directly connected by the grounding device connected to the ground connection, do repeat the ground. What does this mean by repeating the ground?
In fact, you do not have to use a metal copper wire on it.
The neutral line (N pole) of the uninterruptible power supply output terminal is connected to the N pole of the main power supply. The N pole of the main power supply is grounded on the power supply side, so that the neutral line of the uninterruptible power supply output ) Is connected to the earthing line directly connected to the grounding device.
Specifically with a head tied to the UPS shell on the other end of the screw tied with nails and then use the hammer to the nail fixed wall can effectively prevent static electricity
