Safety Precautions
Before you start the installation procedure, read all safety precautions described in this document and observe any warning labels affixed to the remote unit. Doing so ensures your safety and protects the remote unit from damage.
Safety precautions provided in this document may not cover every eventuality, so remain mindful of safety at all times.
Only trained and qualified personnel are allowed to install, operate, or maintain Huawei's remote units.
General Safety Guidelines
Always take precautions against ESD whenever you operate a remote unit. For example, wear ESD gloves or an ESD wrist strap. To avoid electric shock or burn, remove conductive objects like jewelry and watch.
- Ground the remote unit before installing it. Do not operate the remote unit in the absence of a properly installed ground conductor.
- Remove the ground cable only after all the other cables and modules have been removed from the remote unit.
- If electric leakage occurs at the ground point, the remote unit may fail to work properly.
Environmental Safety
Do not install a remote unit in an environment with flammable or explosive gases or smoke.
- Install a remote unit in a dry environment away from sources of water, as water or damp may damage circuits of the remote unit.
- The installation site must be well ventilated to prevent remote units from overheating.
Electrical Safety
- Direct contact with a high-voltage power source or indirect contact through damp objects can be fatal. Misoperations on high-voltage facilities may result in fire, electric shock, or other accidents.
- Never install or remove a remote unit or power cables while the power is on. Transient contact between the core of a power cable and a conductor may generate electric arcs or sparks that can cause fire and hurt human eyes.
- To ensure personal and equipment safety, ground the remote unit before powering it on.
Laser Safety
- Never look directly into an optical module or the ends of optical fibers. Optical modules and connected optical fibers emit laser beams that can cause eye damage.
- Cover fiber connectors with dust caps when they are not connected.
Mechanical Safety
Never attempt to lift objects that are too heavy for one person to handle. Instead, seek help or use appropriate tools.
