Connection To Battery Power Supply; For A Zb-S Station; Connecting The Battery Supply Of A Us-S Substation - Eaton CEAG ZB-S Mounting And Operating Instructions

6 Installation
WARNING!
The battery power supply is a nominal 216V DC!
Improper handling can lead to life-threatening shocks
or burns (arcing)!
Ensure that the battery banks are connected with the
O O
correct polarity.
Turn off all connected loads first («Disable system») to
O O
prevent arcing when the battery circuit is disconnected
(or connection)!
Sequence for making the connections:
Connect the cable labelled „+" to the positive terminal
O O
of the battery bank.
Connect the cable labelled „-" to the negative terminal
O O
of the battery bank.
The battery supply is disconnected in reverse order of
connection.

6.5.1 Connection to battery power supply

for a ZB-S station

The connection cables for the battery power supply
are used to supply the modules in the ZB-S (or US-S)
cabinet and the emergency lighting circuits (switched
across the SKU modules). They are also used to charge
the connected battery banks controlled by the charging
module.
Only when the controller is disabled (at the ZB-S central
battery system and its US-S substations) can the
connections of the battery power supply be safely isolated
with the load disconnector (Batt). The charge modules
and all circuits of the SKUs are not offload until the mains
supply is isolated.
Remember that the connecting cables of the battery bank
(battery cabinet/rack) may still be live!
NOTES:
The connections (+ / –) are accessible when the moving
part of the load disconnector (Batt) is removed (remove
occurs analogical).
Connecting the cables for the battery supply to the ZB-S
control cabinet:
Ensure that the system and feeders are isolated and
O O
locked out!
Connect the positive conductor to the positive terminal
O O
on the load disconntector.
Connect the negative conductor to the negative
O O
terminal on the load disconnector.

6.5.2 Connecting the Battery supply
of a US-S substation
US-S substations are supplied from the power supply of
their associated ZB-S system. An outgoing distributor can
be used for a battery power supply. The central terminal
and related fuses are not used.
NOTES:
To assist operations, outgoing distributors can be pulled
forward off the busbar when the lock on the lower hous-
ing 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.
