6.4 E-STOP CONTACT
The TS HV 70 Outdoor has a quick shut-down (e-stop) function. The unit has a Wago 734-162 two-pin plug
that is accessible from the outside for this purpose. This electrical connection can be connected to an
external control system using the matching Wago 734-102 socket. If necessary, the external control sys-
tem can switch off the unit as quickly as possible using a separate (i.e. completely independent) switch-
ing path. The shutdown is much faster than the normal shutdown process. The wiring connection may
only be implemented using a floating contact.
ATTENTION! Possible damage to the unit due to use of the e-stop.
The e-stop contact is used to quickly shut down the system. As the TS HV 70 Outdoor is not switched off
properly when the e-stop is used, this may lead to damage to the storage system components. For this rea-
son, never use the e-stop to switch off the unit under normal circumstances.
ATTENTION! Possible damage to the APU or external components due to an unsuitable switching
device.
The e-stop contact is at a voltage of 24 V
DC
relative to the potential of the casing. This voltage is created
from the battery voltage by the power supply unit in the APU HV1000-S. Connecting a non-floating
switching device can result in damage to the APU and/or external components.
E-stop states
1.
Contacts 1 and 2 of the Wago plug are connected, e.g. by an external relay; the e-stop is inactive
and the APU HV1000-S is thus switched on.
2.
Contacts 1 and 2 on the Wago plug are open, e.g. after activation of the external switch; the e-stop
is active (this is shown on the APU HV1000-S display); the DC connection between the
TS HV 70 Outdoor and the SMA STPS 60 is interrupted.
Request to the external control system
As the e-stop uses an internal voltage of 24 V
DC
within the unit, external relay switching by means of a
floating contact must be used for correct functioning. This switching can be adapted to match the
requirements of the external control system. The possible circuit situations are shown in the figures
below.

NOTE:
If you are not using the e-stop function, the bridged plug must be fitted to the e-stop connection

as the storage system will otherwise remain inactive!
