DANGER
Danger when connecting the SIPROTEC 5 Compact device
Noncompliance with the safety notes will result in death, severe injury, or 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 prevents condensed water from forming 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.
Perform the electrical inspection.
²
Activating the Battery
NOTE
i
i
The battery is covered by a protective film, which also prevents premature discharge.
The battery compartment is on the underside of the device. Take the battery out of the battery compart-
ment to remove the protective film. Do not pull the insulating film out when the battery slide is closed, as
this may damage the contacts in the battery holder.
NOTE

i
Use only insulated tools to open and close the battery cover and to remove and insert the battery.
Activate the battery for SIPROTEC 5 Compact devices as follows:
Open the battery compartment on the bottom of the device.
²
Fix the insulated tool in the film tab area. Push the battery out using the tool.
²
Remove the protective film.
²
Reinsert the battery.
²
Close the battery compartment on the bottom of the device.
²
Grounding a Device
All SIPROTEC 5 Compact devices, are protection class I equipment and must be connected to the system
ground prior to commissioning.
Ground each module with solid low-impedance system grounding (cross-section ≥ 4.0 mm
²
in
2
), grounding area ≥ M4, torque: at least 1.2 Nm).
In order to ensure the electromagnetic compatibility (EMC) of the device, connect the protective
²
grounding terminals of the modules to each other in series connection. Use the double protective
grounding terminals of the individual modules for this purpose.
Connect the protective conductor of the protection device (connected modules) to the protective
²
grounding terminal of the installation (for example control cabinet) with a single connection to the base
module of the protection device.
