2.6 Install ground cable
2.6.1 Ground cable installation principles
1.The chassis must be well connected to the ground, so that the induction and leakage electricity can flow into
the ground safely, and improve the anti-electromagnetic interference ability of the whole machine.
2.The normal connection of equipment ground wire is the primary guarantee of lightning protection and
interference prevention.
2.6.2 The steps to install ground cable
There is a ground terminal behind the device. The steps of the ground wire connection are as following:
1. Screw down the nut on the ground terminal of the chassis.
2.Put one end of the grounding wire on the grounding post of the rear panel.Tighten the retaining nut.
3.Connect the other end of the ground wire to the wiring terminal.
Warning: the equipment must be well grounded (protection ground), otherwise the equipment can not be reliable
lightning protection, may cause damage to the equipment and the end of the equipment!

Install power cable
2.7.1 Working with power principles:
When working with electricity,one should obey the following principles:
1.Before operation, remove jewelry such as ring, watch, bracelet, etc. Metal items may cause short circuit
when they come into contact with "power" and "ground", which may lead to damage of components.
2.The wrong connection between device and power socket may cause dangerous situation.
3. Only trained and qualified personnel are allowed to operate and maintain the equipment.
It is recommended to use a single-phase three-wire power socket with a ground point.
2.7.2 The steps to install power cable
Before installing the equipment, it is necessary to confirm whether the ground point of the building's
power supply system is buried, and then install the equipment after confirming the burial. It is recommended
to use a single-phase three-wire power socket with a ground connector, and the ground should be reliably
grounded.
Confirm the AC power input range: 100V-240V AC;50HZ-60HZ.
1. Make sure the ground cable has been installed right.
2. Cut off the AC supply power ,keep the power switch being off.
