Requirements for installation location
The Cabinet Modules are designed for installation in closed, electrical operating areas in
compliance with IEC 61800-5-1. A closed electrical operating area is a room or area
containing electrical equipment that can be accessed by trained personnel only. Access is
controlled by a door or other form of barricade that can be opened only by means of a key or
other tool. The room or area is also clearly marked with appropriate warning notices.
The installation location must be dry and free of dust. The air supplied must not contain any
electrically conductive gas, vapors, or dust that could impair operation. It may be necessary
to filter the air supplied to the installation room. If the air contains dust, filter mats (option
M54) can be installed in front of the ventilation grills of the cabinet doors and also in front of
the optional top hats. Option M54 offers additional protection against water sprayed against
the enclosure from any direction and corresponds to enclosure type IP54 (NEMA12
ventilated).
The permissible values for climatic ambient conditions must be taken into account.
At temperatures greater than 104 °F (40 °C) and installation altitudes above 3,300 ft
(1,000 m) (Booksize Cabinet Kit) or above 6600 ft (2000 m) (Chassis), the devices must be
derated (→ see Section "System overview" under Derating data).
The basic version of the cabinet units complies with degree of protection IP20 in accordance
with IEC 60529.
NOTICE
Requirements for IP20
Cabinet Modules do not fulfill the requirements for IP20 until they have been closed off by
installing a side panel on the right (option M26) and a side panel on the left (option M27).
