4.1.2 Power Supply for the S5-95F Basic Unit
The
S5-95F
must be operated with an electrically isolated power supply. The rated voltage is
24
V DC.
24 V DC Power Supply for the S5-95F
If your automation system is made up of basic units
095-8FA02
you can use the same power supply
for both basic units. This is possible because basic units
095-8FA02
have high-grade internal
facilities for monitoring the 24 V DC voltage supply.
Note that in the event of an impermissible voltage rise (V
> 33 V DC) a fuse in the basic unit will
blow. This fuse is installed for safety reasons and you must not replace it yourself under any
circumstances.
24 V DC power supplies must have the following characteristics:
. Safe (electrical) isolation to DIN
VDE
0551/EN 60742 and DIN
VDE
0160
For special applications, it might be necessary to observe additional requirements (see rules and
regulations in Chapter 1 )
. 24 V DC rated voltage
- Permissible tolerance: 20 V to 30 V (including ripple)
. Mains buffering
> 20 ms
We recommend you to use the power supplies of our
SITOP
range in the
S5-95F.
How to Connect the Power Supply to the
S5-95F
Basic Unit
) Connect terminals L + and M of the power supply to the corresponding terminals of the basic
unit (see Figure 4-4).
} Connect terminal 5 of the
S5-95F
basic unit with the standard mounting rail.
