Electrical Data: Single-Phase Pumps - Edwards RV3 Instruction Manual

3.2.7 Electrical data: single-phase pumps

Note:
We recommend using regional supply protection of the maximum ratings specified in
Table: Electrical data (single-phase pumps with Part Numbers ending in -903 or -906)
and Table: Electrical data (single-phase pumps with Part Numbers ending in
Protection of a higher rating must not be used.
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

ending in -904)
lag fuse must be used to prevent unnecessary fuse failure during pump start-up (in
accordance with local and regional electrical codes). Within five minutes, as the oil in the
pump warms up, the current drawn will slowly reduce to the full load current specified
in Table: Electrical data (single-phase pumps with Part Numbers ending in -903 or -906)
and Table: Electrical data (single-phase pumps with Part Numbers ending in
