Page 5: Specified Application
Preface 1.3 Specified application The COMBIVERT R6-S serves exclusively for the supply of frequency inverters with DC input and/or feedback of excess energy into the supply system. The operation of other electrical consumers is prohibited and can lead to malfunctions or to the destruction of the units. -
Page 6: Safety Instructions
COMBIVERT R6 power supply und regenerative units contain dangerous voltages which can cause death or serious injury. COMBIVERT R6 can be adjusted by way that energy is refeed into the supply system in case of power failure at generatoric operation. Therefore a dangerous high tension can be in the unit after switching off the supply system. -
Page 7: Electrical Connection
This is permissible in compliance with the standard, Insulation Mea- since all inverters are given a high voltage test in the end control at KEB in accordance with surement EN 50178. When using components without isolated inputs/outputs, it is necessary that equipotential bonding exists between the components to be connected (e.g. - Page 8 Safety Instructions A trouble-free and safe operation of the COMBIVERT R6 is only guaranteed when the con- nection instructions below are strictly followed. Incorrect operation or damage may result from incorrect installation. • Pay attention to mains voltage. • • Install power cables and control cables separately (>15 cm separation).
- Page 9 Safety Instructions If personnel protection of the system is required, the COMBIVERT R6-S must be protected according to EN 61800-5-1: • • 3-phase inverters (with B6 bridge-connected rectifier) by RCMA’s with separation (used privileged) or RCD’s type B (all-current sensitive FI’s) The tripping current should be 300mA or more, in order to avoid a premature triggering by discharge currents (about 200mA. Dependent on the load, the length of the motor cable and the use of a radio interference filter, substantially higher leakage current can occur.

Keep connection cables straight (do not bundle). Install a non-assigned wire at one sides to the protective earth conductor. • The flow and return circuit must be twisted when the lines are not shielded, in order to dampen common-mode noise. • The cable for phase synchronisation between mains choke and COMBIVERT R6-S may not exceed a line length of 1 m. • Further informations are found in the internet, see „www.keb.de“. -

3) If the DC‑infeed current > 85 A DC use two by two of the DC terminals (++ and ‑‑) to meet the requirements of the UL standard. The connection cables are parallel connected. 4) Please contact KEB for higher values. Voltage stabilization must be activated at the inverter if a harmonic filter is used. -
