PTP and lightning protection
The PIDU Plus meets the low level static discharge specifications identified in
EMC
immunity compliance
on page
4-90
but does not provide lightning or surge
suppression.
The amount of lightning protection is dependent on regulatory requirements and the
end user requirements. The standard ODU for the PTP 600 Series is fitted with surge
limiting circuits and other features to minimize the risk of damage due to nearby
lightning strikes. To be fully effective, these standard features require some additional
equipment to be configured as part of the system installation.
CAUTION
The PTP 600 Series is not designed to survive direct lightning strikes. For
this reason the unit should not be installed as the highest point in a localized
area, unless specific precautions are taken. See

Outdoor connections
The term ‘drop cable’ refers to the cable that is used for all connections that terminate
outside the building, for example, connections between the ODU, LPUs (if installed),
GPS receiver (if installed) and the ODU port of the PIDU Plus.
CAUTION
For outdoor connections, always use Cat5e cable that is gel-filled and
shielded with copper-plated steel. This is the only type of outdoor drop cable
supported in this application. See
