ZyAIR G-5100

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.

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.

Use the included spanner with the mounting screws and nuts.

Note: Make sure the screws are securely fixed to the wall or mast and strong enough to hold the weight

of the ZyAIR with the connection cables.

4.5.1 ZyAIR Mast Mounting

You can mount the outdoor component of your ZyAIR directly to a pole with an outside diameter of 37.5mm ~

62.5mm (1.5" ~ 2.5").

To assemble the ZyAIR mast mounting components:

1 Insert the U-bolt into the mast-mounting bracket and attach the two nuts with one lock washer and one

split-lock washer.
