9. Phase to phase operation
The DRB240 is protected by an internal fuse in the Live line.
When connecting the DRB240 between two phases of a three
phase system an external fuse or circuit breaker must be used
in the Neutral line (N). This is to protect against a fault
between the now 'live' Neutral line and Earth. See section10
for external protection requirements.
Note: The phase-to-phase supply must not exceed the safety
approval input voltage of 100-240VAC+10% and 20A Max
branch circuit current.

10. External Fuse Rating
If required a 250Vac/6.3A rated fuse should be fitted
externally on the input line. Surge current flows when line
turns on. Use slow-blow fuse or time-lag type fuse. Do not
use fast-blow fuse. Fuse rating is specified by in-rush current
value at line turn-on. Do not select the fuse according to input
current (RMS.) values under the actual load condition.
