Setting The Input Voltage - Eaton STS Manuel D'installation Et D'utilisation

Setting the input voltage

Before making any connections, make
sure that the sources selected to
supply the STS are compatible with its
characteristics.
STS 16: 208 V - 220 V - 230 V - 240 V.
STS 1400: 120 V.
The factory input voltage setting for STS
16 is 230 V. If necessary, set the voltage
to another value (208 V, 220 V, 230 V or
240 V) using the voltage selector 14 (see
figure 3).
In the event of an electrical fault, a circuit
breaker on each of the source inputs
protects the STS module.
The voltage selector 14 may be
used only when the STS module
is de-energized, i.e. power
cables 7 not connected to the
sources.
Once the module has been correctly set
up, connect the two power cables 7 to
the two sources.
To facilitate the upstream connection
from the STS 16 to a FR or Schuko
socket, EATON provides, as option, a
2 power cable kit IEC C 19/FR-Schuko
male inlet, 1,90 m length whose part
number is 66397.
