6.4.1.1 Usage of RCDs in the incoming
mains of ZB-S systems
Using RCDs in the mains lead to protect against indirect
contact acc. to VDE 100 part 410, please observe the
following: Fault activations can be caused by different
actions:
O
O
Activation caused by installation failures.
O
O
Activation caused by external actions.
O
O
Activation caused by capacitive leakages.
When designing and executing, it is important to use the
right RCD. Please attend to the following when using
RCDs in the network supplies of systems:
Capacitive leakage
Outgoing line lengths must be included in to the selection
of RCDs.
Example 1:
ZB-S 10C3 with 17 circuits a 100m line length and a RCD
with 30mA release current in the incoming mains. The
total line length exceeds a value of 1500m and can cause
a RCD by line-bound capacitive leakages.
RCD In = 10mA
max. line length = 500m
RCD In = 15mA
max. line length = 750m
RCD In = 30mA
max. line length = 1500m
RCD In = 300mA
max. line length = 15000m
Maximum number of user
In general the isolation resistance is 0.5M at mains
voltage of 230V. That means a leakage of <0.5mA
(230V/0.5M) per user is permissible.
Example 2:
ZB-S 10C3 with 17 circuits and 10 luminaires 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.
6.4.2 Connection to mains of substations
US-S
If the US-S substations are supplied via the power supply
of the corresponding ZB-S system (Pos. 2) then a branching
distributor (article no. 400 71 347 160) for three 1-phase
or one 3-phase current supply must be planned for
connection.
Connecting the cables for the mains supply to a US-S
substation:
O
O
Ensure that the system and feeders are isolated and
locked out!
O
O
Run the feeders to/in the ZB-S control cabinet and in
its trunking (pos. 8) and to/in the control cabinet of the
US-S substation.
O
O
Connect the earth conductor (PE-conductor) to the
terminal block (pos. 5)
O
O
Connect the neutral conductor to the terminal block
(pos. 4)
O
O
Connect the L conductors to the terminals on the
outgoing feeder (pos. 2)
The mains supply is connected in the control cabinet of
the US-S substations as described in section 6.4.1.
NOTE
To assist operations, outgoing distributors can be pulled
forward off the busbar when the lock on the upper enclo-
sure wall is released. Once the outgoing circuits have been
connected, the outgoing distributor can be pushed back in
position on the busbar with slight pressure and locked in
place.
6.5 Connection to battery power supply
Refer to the battery manufacturer´s datasheets that are
enclosed with the CEAG battery banks!
Comply with the statutory requirements and regulations
ruling at the site of the emergency lighting system!
NOTES:
CEAG battery cabinets are supplied as standard with a
cabinet terminal block to which the connecting cables
(+/–) for the battery power supply and a temperature sen-
sor (F+/F–) are connected.
The PE-connection protects live parts of the battery
cabinet (refer to «Installation instructions for Battery
cabinets and Battery racks»).
The connecting cables to the terminals of the
interconnected batteries are not supplied with battery
racks or cabinets. The connection terminal block is not
supplied with battery racks.
O
O
CEAG recommend the installation of the battery
distribution board with disconnector and fuses for the
battery circuit (see «Installation instructions for Battery
distribution board») that allows safe isolation of the
terminals for the connecting leads that run to the ZB-S.
O
O
The battery connection cables (for the ZB-S cabinet and
its US-S substations) must be run with ground fault
and short circuit protection according to DIN VDE 0100
T520!
O
O
The size of these cables must be rated to meet the
anticipated currents flowing to the connected loads.
O
O
Only one temperature sensor (F+ / F–) may be
connected to the charging module LT.1 of the ZB-S
cabinet. Its lead must be run separately to the battery
bank. This can be a 2-core lead with a cross-section of
0.5 mm
2
for lengths < 50m.
O
O
Only one temperature sensor (F+ / F–) must be
connected to the battery control module. Its cable must
be routed separately to the battery bank. A 2-core cable
can be used for this purpose, with a crosssection of
0.5 mm
2
for lengths < 50 m.
