Follow the prescribed electrostatic discharge (ESD) prevention procedures to prevent damage to the
equipment. Static discharge can cause components to fail completely or intermittently over time.
Install the device in a secure area so that only authorized personnel can access the device.

It is particularly important to provide a properly grounded and shielded
Guidelines
To ensure that signaling functions optimally:
Install wires correctly.
Improperly installed wires can emit radio interference.
Do not exceed the recommended distances or pass wires between buildings.
The potential for damage from lightning strikes increases if wires exceed
recommended distances or if wires pass between buildings.
Shield all conductors.
The electromagnetic pulse (EMP) caused by lightning can damage unshielded
conductors and destroy electronic devices.
To reduce or eliminate the emission of RFI from your site wiring:
Use a twisted-pair cable with a good distribution of grounding conductors.
Use a high-quality twisted-pair cable with one ground conductor for each data
signal when applicable, if you must exceed the recommended distances.
