On-site requirements

The Cabinet Modules are designed for installation in closed, electrical operating areas
according to EN 61800-5-1. A closed electrical operating area is a room or area containing
electrical equipment which can be accessed by trained personnel only. Access is controlled
by a door or other form of barricade which can be opened only by means of a key or other
tool. The room or area is also clearly signed with appropriate warning notices.
The installation location must be dry and dust-free. The air supplied must not contain any
electrically conductive gas, vapors, or dust, which could impair operation. It may be
necessary to filter the air supplied to the installation room. If the air contains dust, filter mats
(option M43) can be installed in front of the ventilation grilles in the cabinet doors. Option
M55 offers additional protection against water splashed against the housing from any
direction and corresponds to IP55 degree of protection.
The permissible values for climatic ambient conditions must be taken into account.
Derating is required for ambient temperatures > 40 °C (104 °F) or installation altitudes
> 2000 m (→ refer to the derating data in the "System overview").
The basic version of the cabinet units complies with the IP21 degree of protection in
accordance with EN 60529.
Note
Requirements for IP21
Cabinet Modules do not fulfill the requirements for IP21 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)!
