Watson-Marlow 120 IP31 pumps: general information 9
1.9 Power supply
The 120 pump is suitable for single-phase mains
electricity supplies only via the double-insulated
(Class II) 90-264VAC-to-24VDC mains adaptor. Use
only the approved 24VDC Meanwell type GE24I24-
P1JK DC adaptor or the Powersolve ESA24-24 DC
adaptor supplied with the pump.
A well regulated electrical mains supply is required
along with cable connections conforming to the best
practice of noise immunity. It is not recommended
to site these drives alongside “dirty” electrical mains
supplies such as 3-phase contactors and inductive
heaters without special attention being paid to
unacceptable mains-borne noise.
To prepare your power supply
Select the mains input adapter appropriate to
your region—UK, US, Australia or Europe—and
slide it into position on the rear of the unit.
Ensure it clicks into place.
Stop/start power cycles: Do not power up/power
down for more than 100 starts per hour. A mini-
mum interval of 3 seconds is required between power
cycles.
We recommend using com-
mercially available supply
voltage surge suppression
where there is excessive
electrical noise.
