Grounding cable installation methods
When routing, fastening and connecting grounding cables, the following requirements must be
met:
•
Grounding conductor runs are as short, straight and smooth as possible, with bends and
curves kept to a minimum.
•
Grounding cables must not be installed with drip loops.
•
All bends must have a minimum radius of 203 mm (8 in) and a minimum angle of 90°. A
diagonal run is preferable to a bend, even though it does not follow the contour or run
parallel to the supporting structure.
•
All bends, curves and connections must be routed towards the grounding electrode system,
ground rod, or ground bar.
•
Grounding conductors must be securely fastened.
•
Braided grounding conductors must not be used.
•
Approved bonding techniques must be used for the connection of dissimilar metals.
Siting ODUs and antennas
ODUs and external antennas are not designed to survive direct lightning strike. For this reason
they must be installed in Zone B as defined in
PTP 650 Series User Guide
. Mounting in Zone A
may put equipment, structures and life at risk.
Optical SFP module
The optical SFP module is a Class 1 Laser product. When installing it, observe the following
safety precautions:
•
Do not look into the source of the laser beam (optical receptacle) directly or through an
optical system, as this is highly likely to damage vision.
•
Always remove power from the system before the optical connection is made or unmade.
•
When installing the optical interface, either cap the optical connector, or mate the connector
to an appropriate equipment connector.
•
Ensure that the indoor end of the optical cable is appropriately labeled to ensure that service
personnel are aware the same Class 1 Laser hazard exists.
