DC/DC converter module (R8i) 4.
BDCL filter module 5.
Shielded 3-conductor or 4-conductor cable and 360 degree grounding of the cable shield at the cable
entry. If you use parallel cables, make sure they are identical (type, cross-sectional area, length, etc.).
If you use 4-conductor cable, a separate PE conductor or cable is required if the shield conductivity
does not meed the requirements of IEC 61439-1.

Notes:
Connection of the DC/DC converter unit with parallel power modules: Each module must
have the output cabling of its own. The cablings must also be identical (cable type,
cross-sectional area, and length).
For the cable selection instructions, see Selecting and routing the energy storage
cables (page 56) .
For tightening torgues, see the technical data.
For connecting parallel-connected DC/DC converter modules, see the hardware description.
