Protection of the System
Instructions for Solving Possible Ground Return Problems
To avoid ground return signals from remote systems use the same phase for the dif-
ferent systems' power supply.
If the building's features make this impossible, use an intermediate transformer to
detach the external system so that damage may be avoided during operation.
Protective Ground Connection
Danger
!
The HiPath1130/1150/1190 power supplies must be protected by an earth ground in
a separate safety ground conductor (PE - green/yellow) (TN-S system, minimum sec-
tion = 2.5 mm
Any additional servicing of low voltage networks (100 - 240 V AC) must be done by
qualified technical personnel only.
Do not use as a grounding point:
- Central heating systems
- Sewer systems
- Ground wire for antennae systems.
Failure to comply with these recommendations may lead to hazardous conditions.
