DANGER
Danger when connecting the SIPROTEC 5 device
Noncompliance with the safety notes will result in death, severe injury, or considerable material
damage.
²
The device must be situated in the operating area for at least 2 hours before you connect it to the
power supply for the first time. This prevents condensed water from forming in the device.
²
If the device has been in storage for more than 2 years, connect it to an auxiliary voltage for 1 to
2 days. This will cause the electrolytic capacitors to form on the printed circuit board assemblies again.
²
Perform the electrical inspection.
