• The intensity of earthquake should not exceed level 8
• Humidity
- Highest average value measured over 24 hours
o Relative humidity
95 %
- Highest average value measured over 1 month
o Relative humidity
90 %
Special operating conditions
SecoGear is suitable for operation in the climate of indoor
type according to IEC 62271-200 standard. Special operating
conditions must be discussed with the manufacturer in advance.
For example: At site altitudes above 1000 m, the effects of the
reduction in density of air on the dielectric properties must be
taken into account.
Increased ambient temperatures must be compensated for in
the design of the busbar and the branch conductors as well as
the withdrawable parts; otherwise the current carrying capacity
will be reduced. Fitting additional ventilation facilities can assist
heat dissipation in the switchgear panel.
Note on any special climatic operating conditions
When the switchgear is operated in areas with high humidity
and/or major rapid temperature fluctuations, there is a risk
of condensation. Preventive actions (e.g. applying an electric
heater) must be consulted with the manufacturer to avoid
condensation and any resulting corrosion or other adverse
effects. The control of the heaters depends on the particular
project are available.
Safety and Environment Protection Requirement
Safety Procedure
•
Wear safety uniform according to electric safety regulations before entering the site
•
Comply with industry work procedure. Power supply shall be operated by authorized staff.
Environment protection requirements
The manufacturer has a product recycle policy in accordance
with related law and ISO14001. Local laws shall be observed
when the switchgear is due for recycle.
