ELECTRICAL CONNECTIONS
Electrical installation must be carried out by qualied personnel
who are conversant with local electricity installation regulations.
Before starting any electrical installation work ensure that the main
electrical supply is adequately isolated.
Ensure that the pump motor is earthed. The pump may be electrically
isolated from the motor depending on the mounting conguration.
Some installations may need an earthing connection on the pump head.
Pumping ammable uids without a proper earthing connection may
cause spontaneous ignition.
Ensure that all electrical connections use a common earth ground to
avoid hazardous ground loops.
MAIN Power In
24 +/- 12Vdc (nominal), voltage ripple must be maintained below 5% peak-to-peak,
from SELV Class2 or Limited Power Source, Micropump always recommends
external overcurrent protection (MODEL MS ~2A, MODEL EL ~3A), internal
hardware-current-limit decreases motor speed to hold at current limit until rotation
stops (stall), in locked-rotor condition maximum stall current is ~1.2A.
If locked rotor operation occurs at full load current in greater
than 70°C ambient temperature conditions can result in winding
temperatures greater than UL 1004 limits. To reduce risk of
exceeding winding temperature limits Micropump recommends
always monitoring the tachometer signal and commanding stop
if the pump shows a locked rotor condition lasting more than
one minute.
Ensure that the voltage of the supply is correct for the motor being
connected, and that the source is SELV Class 2 or a Limited Power
Source. Ensure that the power supply voltage ripple is maintained
below 5% peak to peak.
Ensure that all associated equipment has a form of overcurrent
protection. If a fuse is used see table below for recommendations.
