Preparatory measures

Automatic

Restart

The COMBIVERT R6 can be adjusted by such way that the inverter restarts automatically

after an error case (e.g. broken phase line). System design must take this into account, if

appropriate, and additional monitoring or protective features added where necessary.

Not Short-Cir-

cuit Proof

(Supply)

The COMBIVERT R6 is not short-circuit proof at the power supply input ! If the I2t-protection

is adapted with a gR fuse, a conditional protection at supply input is possible. The short-cir-

cuit protection at DC output is if applicable ensured by internal or external aR respectively

gR fuses.

Conditionally

Short-Circuit

Proof

(Feedback)

The COMBIVERT R6 is conditionally short-circuit proof (EN 61800-5-1 / VDE 0160). After

resetting the internal protection devices, the function as directed is guaranteed.

Exception:

if an earth-leakage fault or short-circuit often occurs at the output, this can lead to a defect

in the unit.

Cyclic Acti-

vation And

Deactivation

With applications requiring the COMBIVERT R6 to be switched on and off cyclically, main-

tain an off-time of at least 5 min. Switching off during the initialization phase can cause

undenedconditions.IfyourequireshortercycletimespleasecontactKEB.

RCD (Resid-

ual Current

Operated Cir-

cuit-Breaker)

When using systems with RCD, the instructions or the requirements of VDE 0100 -T 530

(IEC 60364-5) must be observed. The recommended tripping current of the RCD type „B“

is 300 mA.
