ZyAIR B-5000 Quick Installation Guide

4.2 Grounding

A safe grounding system is necessary to protect your outdoor installation from lightning strikes and the build-up of static electricity.

Direct grounding of the antenna mast, Outdoor Access Point & Bridge and Surge Arrester are very important. The ZyAIR has a built in Surge Arrester. The ZyAIR should be connected to the same grounding system as the antenna mast and the AC wall outlet.

The grounding system must comply with the National Electrical Code and safety standards that apply in your country. Always check with a qualified electrician if you are in doubt as to whether your outdoor installation is properly grounded.

4.3 What is Lightning Protection?

All outdoor electronic equipment is susceptible to lightning damage. Proper grounding to national and local codes is instrumental in providing human safety. Lightning Protection is used when a customer wants to maximize the reliability of the electronic system by diverting the excess energy that can be induced on any transmission lines (data, power) though a series of surge protection devices. The energy is dissipated through heat and is also diverted to the ground.

4.4 Why is Additional Protection Recommended?

Lightning, even with the built-in protection, can still damage ZyAIR equipment. This can occur for any number of reasons, such as an improperly grounded installation or if the amount of transient energy from nearby lightning exceeds what the devices can handle.

If the ZyAIR unit fails due to damage from lightning, the link is out-of-service until the unit is replaced or repaired. An external, reverting protection device can provide a higher level of protection, and greater probability of surviving lightning strikes without damage to the ZyAIR equipment.

4.5 Unpacking the ZyAIR

The ZyAIR’s shipping box should be left intact and sheltered until arrival at the installation site. If the shipping container shows signs of damage, immediately notify the transportation company. Upon receipt, inspect contents to make sure that there are no missing or damaged parts (see Packaging Specifications in the appendix of the ZyAIR User’s Guide).

Retain all the packing materials (including all internal boxes). In the unlikely event that the equipment must be returned, use the original packing materials for return shipment. The packing materials are also recommended for transporting the equipment from location to location.
