Storage

NOTICE

HAZARD OF NOT RESPECTING THE STORAGE CONDITIONS

Respect the following storage conditions:

• The equipment must be stored in a dry area free from dust and with limited

temperature variations.

• The equipment must remain in its original packing.

• The equipment must be stored under shelter, on a dry floor or on a material

insulating it from the damp.

Failure to follow these instructions can result in equipment damage.

Installation and Operation Recommendation

Switchgear Ageing Withstand

NOTICE

HAZARD OF NOT COMPLYING WITH THE MAIN FACTORS ALLOWING

SWITCHGEAR AGEING WITHSTAND

Comply with the three main factors that enable switchgear ageing withstand in

an MV substation:

• Perform proper connection implementation: use the new cold slip-on and

retractable technologies that offer ease of installation, thereby promoting

withstand over time. Their design enables operation in polluted

environments with harsh atmospheres.

• Avoid the influence of the relative humidity factor: install heating resistors in

climates with high relative humidity and large temperature differences.

• Control ventilation: check the grids are sized according to power loss in the

substation. Place the grids near the transformer, so as to prevent air

circulating on the MV switchboard.

Failure to follow these instructions can result in equipment damage.

18 NNZ1587001-04

Generalities SM AirSeT - Up to 24 kV and 630 A Modular Cubicles

Operation

Schneider Electric strongly recommends that you carry out at regular intervals (at

least roughly every 2 years) a few operating cycles on the switching devices.

Outside normal operating conditions (from -25°C to +40°C (from -13°F to 104°F),

absence of dust, corrosive gas, for example), contact your Schneider Electric

service center in order to examine the measures to be taken to help ensure proper

installation operation.

The Schneider Electric service center is at your disposal at all times:

• To conduct an installation diagnosis.

• To suggest the appropriate maintenance operations.

• To offer you maintenance contracts.

• To suggest adaptations.
