Grounding The Switch With A Grounding Strip - NEC QX-S5500G Series Installation Manual

Installation Guide
QX-S5500G Series Ethernet Switches
The power input end of the switch has a noise filter, whose central ground is directly
connected to the chassis to form the chassis ground (commonly known as PGND). You
must securely connect this chassis ground to the earth so the faradism and leakage
electricity can be safely released to the earth to minimize EMI susceptibility of the switch.
You can ground the switch in one of the following ways, depending on the grounding
conditions available at the installation site:

Grounding the switch with a grounding strip


Grounding the switch with a grounding conductor buried in the earth ground

Grounding the switch by using the AC power cord

 NOTE:

3.4.1 Grounding the switch with a grounding strip
If a grounding strip is available at the installation site, connect the grounding cable to the
grounding strip.
1) Cut the grounding cable as appropriate for connecting to the grounding strip.
2) Peel 5 mm (0.20 in) of insulation sheath by using a wire stripper, and insert the bare
metal part through the black insulation covering into the end of the ring terminal
supplied with the switch.
3) Secure the metal part of the cable to the ring terminal with a crimper, cover the joint
with the insulation covering, and heat the insulation covering with a blow dryer to
completely cover the metal part.
