The neutral line (N pole) at the output of the uninterruptible power supply must be connected to the grounded line directly from the grounding device, repeating the ground. What does it mean to do repeated grounding?
The neutral line (N pole) of the output of the uninterruptible power supply is connected to the grounded line directly connected to the grounding device, i.e., repeating the ground.
The neutral line (N pole) of the output of the uninterruptible power supply is connected to the N of the main power supply. The N of the main power supply is grounded on the power supply side,
In fact, you don't have to. You can use a copper wire. The concrete is a tied in UPS shell screw on the other end tied on the nail with a hammer and nails fixed wall can effectively prevent electrostatic
