Grounding and Connecting Devices

3.1.4
Grounding the Devices
The SIPROTEC 5 devices are protection class I equipment must be connected with the system ground before
commissioning.
!
DANGER
Danger due to device being improperly grounded
Incomplete and careless grounding leads to death, severe injury, and considerable material damage!
The device must be situated in the operating area for at least 2 hours before you connect it to the
²
power supply for the first time. This method prevents condensation of water in the device.
If the device has been in storage for more than 2 years, connect it to an auxiliary voltage for 1 to 2
²
days. This will cause the electrolytic capacitors to form on the printed circuit board assemblies again.
Ground each module with solid low-impedance system grounding (cross-section ≥ 4.0 mm
²
grounding area ≥ M4).
Connecting Devices
Connect all cables and leads. Use the connection diagrams in the Hardware and Device manuals.
²
Tighten the terminal screws to the prescribed torques.
