6.4 E-stop contact
The STORAGE-67-TS-10 has a quick shutdown (e-stop) function. An externally accessible two-pin plug (type
734-162 manufactured by WAGO) is provided on the device for this purpose. This electrical connection can be
connected to an external control system via the corresponding WAGO 734-102 socket. If necessary, the exter-
nal control system can switch off the unit as quickly as possible using a separate, i.e. completely independent,
switching path. This shutdown is considerably faster than the normal shutdown process. The switching may only
occur via a potential-free contact.
ATTENTION! Risk of damage to the unit through use of the e-stop!
The e-stop is used to quickly shut down the system. Since the battery storage system is not switched off properly
when the e-stop is used, damage may be caused to components of the STORAGE-67-TS-10. you must therefore
never use the e-stop to switch off the unit under normal circumstances.
ATTENTION! Risk of damage to the APU or external components due to an unsuitable switching
unit.
The e-stop contact has a voltage of 24 V
DC
relative to the potential of the casing. The voltage is drawn by the
power supply unit of the SMA HV APU from the battery voltage. Connecting a potential-free switching device
can cause damage to the APU and/or the external component.
E-stop states
1 . Contacts 1 and 2 of the Wago plug are connected, e.g. via an external relay, the e-stop is inactive and the
SMA HV APU is therefore switched on.
2 . Contacts 1 and 2 from the Wago plug are open, e.g. after activation of the external switch, the e-stop is
active (shown on the display of the SMA HV APU), the DC connection between STORAGE-67-TS-10 and
STPS 60-10 is interrupted.
Requirement for the external control system
Since the e-stop uses an internal voltage of 24 V
DC
, external (relay) switching via a potential-free contact must be
employed to ensure proper functioning. This switching can be adapted to match the requirements of the external
control system. The possible electrical connections are shown in the figures below.
