The motors conform to degree of protection IP 55 as per IS 4691 / IEC 60034-5. Higher protection on request.
The standard design for horizontal mounting is suitable for indoor and protected outdoor installation (temperature of coolant -20°
to + 50°C).
For unprotected outdoor installation or severe climatic conditions (moisture category wet, climate group WORLDWIDE, extremely
dusty site conditions, aggressive industrial atmosphere, danger of storm rain and coastal climate, danger of attack by termites, etc.),
as well as vertical mounting, special protective measures are recommended, such as:
• Protective cowl (for vertical shaft-down motors)
• For vertical shaft-up motors additional bearing seal and flange drainage
• Special paint finish
• Treatment of winding with protective moisture-proof varnish
• Anti-condensation heating (possibly winding heating)
• Condensation drain holes
The special measures to be applied have to be agreed with the factory once the conditions of installation have been settled.
