Siemens recommends that all devices be installed so that they are not exposed to direct sun-
light nor subject to large fluctuations in temperature that may cause condensation to occur.
The protection device is designed for installation in normal relay rooms and plants, so that elec-
tromagnetic compatibility (EMC) is ensured if installation is done properly.
In addition the following is recommended:
• Contacts and relays operating within the same cabinet or on the same relay board with
digital protection equipment, should be in principle provided with suitable fuses.
• For substations with operating voltages of 100 kV and above, all external cables should be
shielded with a conductive shield grounded at both ends. Normally in medium voltage
systems no special procedures are necessary.
• Do not withdraw or insert individual modules/boards while the protective device is ener-
gized. In withdrawn condition, some components are electrostatically endangered; during
handling the ESD standards (for Electrostatic Sensitive Devices) must be observed. They
are not endangered when inserted into the case.
