Making the electrical connections

NOTE
Select conductor cross-section, safety type and safety value in accordance with the following basic condi-
tions:
Country-specific installation standards; power rating of the device; cable length; type of cable installation;
local temperature
Detailed information on tightening torques: See comprehensive operating instructions under
ergy.com/de/downloads
4.3 Configuring the DC cable
↻ DC cables inserted through the input plate.
↻ CAUTION! Risk of fire due to chemical corrosion. Cable lugs must be suitable
for the conductor material and copper busbars being used .
↻ WARNING! Risk of short circuit due to incorrect size of the cable lug! Observe
the dimensions for the selection. [See figure 4] [} Page 73]
1 Fit the DC cables with a ring cable lug. When crimping, ensure that the ring ca-
ble lug is rotated in accordance with the final installation position. [See figure
5] [} Page 73]
WARNING! Danger to life due to a surge in voltage. If the clearance is insuffi-
cient, shrink tubing (>= 6 kV/mm dielectric strength) must be used.
F Guide the shrink tubing over the uninsulated crimping point and a maximum of
+0/-2
20 mm over the cable insulation and shrink-fit using manual shrink-fitting
equipment.
F Draw in cables to the indicated fixing length and run with cable fitting.
ð DC cable configured. Continue with the connection to DC switch.

Connecting the DC cable to the DC switch
NOTE: For installation of the DC cables, use a torque wrench as well as the in-
cluded open-ended wrench for counter-resistance.
