Watson-Marlow 520DuN IP66/NEMA 4X User Manual

Input line fusing

: type T2,5A H 250V

20mm time-delayed fuse, located in a
fuseholder in the centre of the switch-
plate at the rear of the pump.

Power interruption

: This pump has

an auto-restart feature which, when
active, will restore the pump to the
operating state it was in when power
was lost. See 18.12

Auto-restart

Stop / start power cycles

: Do not

power up/power down for more than
100 starts per hour, whether manually or
by means of the auto-restart facility. We
recommend remote control where a high
frequency of power cycles is required.
