GPS overvoltage concept
When using the GPS protector, the GPS supply lines at the entry into the building
should be safeguarded against high overvoltages by a grounded lightning surge protec-
tor.
The GPS protector is a passive and thus maintenance-free hardware component
mounted on the GPS antenna connection of the equipment rack.
Installing the GPS protector
Preparation:
The site must be prepared in compliance with the document "Site Requirements".
The equipment rack must be connected to the grounding system.
The toggle switches must be set to the "Off" position ("downward" switch position).
Carry out the following steps:
Risk of damage from electrostatic discharge (ESD)
The base station can be damaged if antennas are connected or disconnected during
the switched-on state. The GPS antenna connection is particularly sensitive to electro-
static discharge (ESD).
Ensure that the base station is switched off before connecting or disconnecting
antennas.
Install the GPS protector on the GPS antenna connection applying a tightening
torque of 100 Ncm using a size 18 dynamometric key.
