The other trademarks mentioned in this document, registered or not, belong to their respective holders.This user manual only applies to 12 and 17.5 kV Functional Units

ResponsibilitiesOur devices are quality controlled and tested at the factory in accordance with the standards and regulations currently in force.Apparatus efficiency and apparatus life depend on the compliance with the installation, commissioning and operation instructions described in this user manual. Non-compliance with these instructions is likely to affect your guarantee rights. The texts in this user manual make reference to international regulations.Local requirements especially about safety which are in accordance with the indications given in this document, must be observed.

Reminder concerning normal operating conditions In accordance with IEC 60694.

Permissible ambient temperature The ambient air temperature must remain within - 15° C and + 40° C. The average measured value for a 24 hour period must not exceed 35° C.

Installation altitude MV equipment can be operated up to an altitude of 1,000 m. If this altitude is exceeded, account must be taken of the decrease in the dielectric rigidity of the air, leading to a decrease in insulation. If such is the case, use substation switchgear of a higher voltage range.

Atmospheric pollution There must be no dust particles, fumes or smoke, corrosive or flammable gases, vapours or salts.

Permissible atmospheric humidity level The average value of atmospheric humidity in a 24 hour period must not exceed 95 %. The average water vapour pressure over a period of 24 hours must not exceed 22 mbar. The average atmospheric relative humidity value measured over a period of one month must not exceed 90 %. The average water vapour pressure over a period of one month must not exceed 18 mbar. Condensation may appear in case of any sharp variation in temperature, due to excessive ventilation, a high atmospheric humidity level or the presence of hot air. This condensation can be avoided by an appropriate lay-out of the room or of the building (suitably adapted ventilation, air driers, heating etc.). Whenever the humidity level is higher than 75%, we recommend that you take appropriate corrective measures for which Schneider Electric can offer you the necessary assistance. Do not hesitate to contact us.
