Note:
Edwards recommends using fuses of the maximum ratings specified in
and
. Do not use fuses of a
higher rating.
The dual-voltage, dual-frequency motor is designed for a single-phase electrical supply and is suitable for 50 Hz or
60 Hz operation. The motor can be manually switched between nominal supply voltages of 110-120 V and 220-240 V
(refer to
When starting a cold pump, the motor will draw a start-up current for up to several seconds, therefore use a
slow-blow fuse to prevent unnecessary fuse failure during pump start-up. Within five minutes, as the oil in the pump
warms up, the current drawn will slowly reduce to the full load current specified in
and
.
Sound pressure: measured at ultimate vacuum 1 metre from the
end of the pump to ISO 11201, 50 Hz electrical supply
