Put a transient voltage suppressor (TVS) between each output terminal (A through D) and the common terminals (U).  Do a search of the forum for advice about sources and part numbers.

It's also a good idea to put a circuit breaker or fuse in series with each output terminal.  The best circuit breakers for this application are auto-resetting thermal automotive fuses, which you can find at auto parts stores.  Use a circuit breaker appropriate for the wire size that you are using, but no more than 15 amperes.
