DIB-500 R4.1 Requirements concerning the electrical system
Voltage supply
Table 5.4 describes the number of rectifier modules as a factor of the voltage supply.
Recommended connection
For installation and service purposes, the availability of a 230 V
AC
mains socket for
plugs with earthing contact in the operation room is recommended. This power connec-
tion must be identified appropriately.
The following sections describe the requirements concerning the electrical system as a
factor of the power supply:
| Voltage supply (VDC)
| Voltage supply (VAC)
5.2.1 Voltage supply (V
DC
)
To ensure the proper operation of the product, the requirements concerning the follow-
ing location constituents must be met:
| Voltage supply connector (VDC)
| Cable specifications of voltage supply cables (VDC)
| Fuse protection (VDC)
5.2.1.1 Voltage supply connector (V
DC
)
For the proper operation of the product, a voltage supply connection according to the
type of connection must be available in the operation room.
Standards and Guidelines
The requirements to the power supply of telecommunications equipment with direct cur-
rent (DC) can be found in ETSI EN 300 132-2 V2.1.2.
To control voltage fluctuations and to protect the product against voltage failures, the
use of an uninterruptible power supply (UPS) is advisable.
