DIB-500 R4.1 Requirements concerning the electrical system
Voltage supply
One Schuko plug in compliance with CEE 7/VII for each integrated rectifier module is
included in the scope of delivery and already installed upon delivery. The voltage supply
cable(s) are identified according to the related rectifier module, e.g. "PSU1".
Removing Schuko plugs
The Schuko plug can be removed when the DIB-500 R4.1 system is to be connected to
a fixed connection (e.g. distributor box). In this case, the strand ends of the voltage sup-
ply cable/s must be fitted with end sleeves for strands.
5.2.2.2 Cable specifications of voltage supply cables (V
AC
)
In the version of the product/system with V
AC
voltage supply, one voltage supply cable
per rectifier module is available via the mounting frame. The voltage supply cable(s) is/
are routed out through the grommet of the equipment rack. This/these voltage supply
cable(s) is/are already connected to the mounting frame and can be connected to the
voltage source on site.
5.2.2.3 Fuse protection (V
AC
)
Each equipment rack (apart from the equipment rack(s) of the cavity variant) of the
DIB-500 R4.1 features a connection panel, via which the integrated components are
supplied with voltage and grounded.
Insufficient fuse protection of the power supply may impair the operation of the product.
The construction of automatic circuit breakers depends on the characteristics of the
required voltage supply cable (power consumption, refer to section 5.2.1.2 on page 34)
as well as the length of cable.
Standards and Guidelines
Required measures for the construction of automatic circuit breaker can be found in
IEC 60950-1, Information technology equipment – Safety, part 1: General Require-
ments.
In the case of a V
AC
voltage supply, the voltage supply source on site must be protected
by an appropriate overload protection for each supply line independent of the connec-
tion variant.
Table 5.7 describes the requirements concerning the overload protection on site by an
external fuse. This overload protection protects the cable between the voltage source
and the mains socket/fixed connection.
