6.3 Installation of the components
DANGER! Life-threatening electric shock if ground is insufficient or absent!
If an error occurs in the unit, an insufficient or absent ground can cause damage to the unit. This poses the risk of
a lethal electric shock.
1
First, ground the battery cabinet. To do this, connect the ground cable
7 .5
to one of the grounding points of the
cabinet.
NOTE Before installing the SMA HV APU, note its serial number. This is located on a sticker on the underside
of the cabinet.
2
Grounding the SMA HV APU is absolutely essential. Connect the
ground cable
4 .4
to the grounding bolt on the back of the
SMA HV APU
14
via the M 6 ring terminal. Use a torque wrench and a
tightening torque of 6 Nm.
3 Place the SMA HV APU in the left half of the cabinet onto the third slide
rail from the top. Connect the M 8 ring terminal at the free end of the
ground cable
4 .4
to the grounding point on the rear upper cabinet
frame (see marking in the figure). Use a torque wrench and a tightening
torque of 10 Nm.
4
Now place the SMA HV APU in the left half of the cabinet on the
uppermost slide rail. Fasten it to the pre-fitted cage nuts with four
M 6 x 16
11 .4
screws incl. washers.
5
The two-pin plug for the e-stop connection on the SMA HV APU must be
plugged in for operation. The SMA HV APU will remain inactive until the
plug is connected. For more information on the e-stop, please refer to
section “6.4 E-stop contact“ on page 27 of these installation and
operating instructions.
6
All battery modules in a STORAGE-67-TS-10 battery storage system must have exactly the same state of charge.
Make sure you check the voltage of the battery modules before assembly. The correct voltage of a battery mod-
ule upon installation must be 50.0 +/- 0.1 V
DC
. Should you identify any discrepancies, please contact our service
center.
