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 condensate 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 on the printed circuit-board assemblies to form again.
²
Perform the electrical inspection.
Activating the Battery

Grounding a Device
The SIPROTEC 5 devices are protection class I equipment must be connected with the system ground prior to
commissioning.
²
Ground each module with solid low-impedance system grounding (cross-section ≥ 4.0 mm
2
(≥ 0.0062 in
2
), grounding area ≥ M4, torque: at least 1.2 Nm).
Connecting a Device
²
Connect all cables and lines. Use the connection diagrams in the Hardware and Device manuals.
²
Tighten the terminal screws to the prescribed torques (see chapter Tightening Torques for Terminal
Screws, Page 213).
Grounding an On-Site Operation Panel
²
Join several on-site operation panels to one another with firm contact.
Siemens recommends the use of contact washers on painted metal mounting walls. If the mounting wall
is not metallic, place a metal layer, for example a metal sheet, between the mounting wall and the on-
site operation panels. Then connect this sheet to the system grounding.
