Warning
In certain local mains networks, the neutral wire (marked with "N") is not connected to
ground potential. In this case, the neutral (N) and all three phases (L1 to L3) must be con-
trolled by a four-phase automatic circuit breaker. In case of an error, the circuit breaker
must disconnect all power lines (N, L1, L2 and L3) from the mains network. (Please refer to
your local regulations.)
Warning
If the potential of your neutral wire (N) is floating compared to ground (PE) in such a way
that the voltage between ground (PE) and any of the remaining power lines (L1, L2, L3)
may exceed 254 V, you need an isolating transformer connected upstream of the S8. In
order to maintain tolerable voltage levels tie the secondary winding (N') to ground (PE).
If a residual current circuit breaker is used, it must be designed for a triggering current of at least
30 mA.
For the installation, a wall outlet or terminal box should be located no further than 5 m (16') from the
S8 TIGER.
Moreover, additional protective grounding (grounding resistance d 0.5 :) in accordance with the local
regulations may be provided.
Figures 1-2 through 1-5 show various mains connection options of the S8-3kW/4kW system. The fig-
ures 1-6 and 1-7 show the mains connection options of the S8-1kW system.
