Mounting- and Operating Instruction CEAG DualGuard-S
40071860347 January 2020 www.ceag.de
6 Assembly and installation of the DualGuard-S
strand monitors may be connected to the Battery Control
Module BCM.1. Its cable must be routed separately to the
battery bank. A 2- to 8-core cable can be used for this pur-
pose, with a cross-section of 0.5 mm2 for lengths < 50 m.
WARNING!
The battery power supply is nominal 216 V DC! Improper
handling can lead to life-threatening electric shocks or burns
(due to arcing)!
Ensure that the polarity of the battery banks is correct.
Switch off all connected consumers beforehand („Block
the system via the colour touch display“) so that no elec-
tric arcs occur when the battery circuit is disconnected (or
connected)!
NOTE!
Sequence of connection:
• Connect the cable marked „+“ to the positive terminal of
the battery bank.
• Connect the cable marked „-“ to the negative terminal of
the battery bank.
• When disconnecting the battery power supply, the reverse
order applies.
Connecting the Battery Supply
The connecting cables for the battery power supply supply
supply the modules of the DualGuard-S (or sub-distribution
boards) and the emergency lighting circuits (switched via
the SKU.1.1 modules). Furthermore, the charging of the
connected battery banks is controlled via the BCM.1 module.
Only when the control is blocked may the connections of the
battery power supply be switched off without danger via the
load-break switch (Batt). Charging modules and all circuits
of the SKU.1s are then disconnected only after the mains
power supply has been switched off. Please note that the
connection cables from the battery bank (battery cabinet/
frame) may still be live!
NOTE!
The connections (+ / -) are accessible when the moving part
of the switch-disconnector (Batt) has been removed (removal
is analogous).
Connect the cables for the battery power supply of the
DualGuard-S switch cabinet:
Make sure that the system and the supply lines are discon-
nected!
Connect the positive conductor to the positive terminal of
the switch-disconnector.
Connect the negative conductor to the negative terminal of
the switch-disconnector.

Sub-distributor connection
Connection of the battery supply of a sub-
station
Substations are supplied via the power supply of the asso-
ciated DualGuard-S system. An outgoing distributor can be
used for a battery power supply. The middle terminal and
associated fuse are not used.
NOTE!
To make work easier, outgoing distributors can be removed
from the busbar to the front when the lock on the anderside
of the housing is released.
Once the outgoing cables have been connected, the out-
going distributor can be reattached to the busbar with slight
pressure and snapped into place.
