DIB-500 R4.1 Requirements concerning the electrical system
Voltage supply
36 Site Requirements 90DIB500R41SR_FCC02 – 99.1
The DIB-500 R4.1 is equipped with an automatic cutout for each transceiver module.
The properties and demands on the fusing to ensure tripping of the automatic cutouts
are described in the following.
Table 5.6 describes the properties and demands on the fusing for a V
DC
voltage supply.
5.2.2 Voltage supply (V
AC
)
To ensure the proper operation of the product, the requirements concerning the follow-
ing location constituents must be met:
| Fuse protection (VAC)
| Cable specifications of voltage supply cables (VDC)
| Fuse protection (VDC)
5.2.2.1 Voltage supply connector (V
AC
)
For the proper operation of the product, a voltage supply connector according to the
connection type in the operation room must be available.
Country-specific laws and provisions
Always observe the applicable laws and regulations of the respective country for setting
up low-voltage systems.
With a V
AC
voltage supply, the product/system can be connected to the voltage source
on site in the following connection variants:
| to a fixed connection (e.g. distributor box),
with this connection variant, an easily accessible separator must be available in the
voltage supply circuit of the voltage source, such as a fuse in the sub-distribution, or
| with Schuko plug at the mains socket(s),
with this connection variant, the mains socket(s) must be easily accessible and
located as close to the product as possible. The length of the voltage supply cable
limits the possible distance. The length of the voltage supply cable provided is
2.5 m.
