4.4 Preparing the DC connections
DANGER!
Risk of death by electrocution!
– Observe the warning notes in
Ä 4.1, p. 102 .
– coolcept: Opposing Multi-Contact connectors must be used for the DC cable to suit the Multi-
Contact MC4 plug connectors (opposing connectors optionally available).
– coolcept-x: Use the SunClix plug connectors provided to ensure that the specified degree of
protection is maintained.
ATTENTION!
Danger of damage to the inverter and the modules. Connect the opposing connectors for the DC
connections to the DC cable, observing the correct polarity.
1. Attach the connector plug counterparts to the DC cable according to the manufacturer's
instructions; see Appendix.
2. If legally prescribed (e.g. France), plug in the optionally available safety sleeves, according to
