Connection of the Mains Power Supply to EURO ZB.1
Mains Connections to Substations EURO US.1
Power is supplied to a EURO ZB.1
system via the general power system or
the batteries of a battery bank (battery
cabinet or rack).
In case of a 1-phase operation only a
load-current line is connected to the sy-
stem and the input terminals (see Fig. 22,
Item 2) are bridged on the isolator.
Note:
Only carry out the connecting work
described here.
Switching on and testing the po-
wer supply systems is described
in Chapter 12 „Commissioning
and Miscellaneous Work“!
Connect the lines for mains power
supply to the EURO ZB.1 control
cabinet as follows:
– Make sure the system and inco-
ming feeders have been discon-
nected and safeguarded (cf.
Chapter 12)!
– Connect the protective conductor
to the PE terminal block (Fig.19,
Item 3).
– Connect the neutral conductor to
the N terminal block (Fig.19, Item
2).
– Connect the load lines to the L
terminals (Fig. 22, Item 2) of the
load-break switch.

Substations EURO US.1 are energized
via the power supply of the pertinent
EURO ZB.1 system (see outgoing distri-
butor in Fig. 20, Item 3 and outgoing lines
in Fig. 22, Item 4).
An outgoing distributor (reference No.
400 71 347 160) can be employed for
three 1-phase power supply systems.
Notes:
Only carry out the connecting
work described here. Switching
on and testing the power supply
systems is described in Chapter
12 „Commissioning and Miscella-
neous Work“!
To facilitate work outgoing
distributors may be removed from
the conductor rail in forward di-
rection after the catch on the top
casing wall is released (see arrow
in Fig. 23).
After the outgoing lines have been
hooked up the outgoing distribu-
tor can be replaced in position on
the conductor rail and carefully
snapped into place.
Connect the lines for mains power
supply to a EURO US.1 substation as
follows:
– Make sure the system and inco-
ming feeders have been discon-
nected and safeguarded (cf.
Chapter 12)!
– Lay the incoming lines to/within
the EURO ZB.1 control cabinet
and in its cable ducts (Fig. 18,
Item 3 and Fig.22, Item 3) and to/
within the control cabinet of the
EURO US.1 substation.
– Connect the protective conductor
(PE conductor) to the terminal
block (Fig.19, Item 3).
– Connect the N conductor to the
terminal block (Fig.19, Item 2).
– Connect the L conductors to the
terminals of the outgoing distribu-
tor (Fig. 20, Item 3).
Note:
The mains power supply is
hooked up within the control ca-
binet of the EURO US.1 substati-
ons, as described under 11.2.
Example 2:
ZB-S 10C3 with 17 circuits and 10 lumi-
naires per circuit and a RCD with 30mA
in the incoming mains.
17 x 10 x 0.5mA = 85mA leakage
The addition of the single leakages of the
connected user to the RCD exceeds a
value of 30mA and can cause the RCD.
