Edwards RV3 Instruction Manual

3.2.7 Electrical data: single-phase pumps
Note:
We recommend using regional supply protecon of the maximum rangs specied 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 -904).
Protecon of a higher rang 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 operaon. The motor can be manually switched
between nominal supply voltages of 110‑120 V and 220‑240 V (refer to Check and
congure the motor on page 27). When a cold pump is started, the motor will draw the
start-up current shown 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 -904) for up to several seconds. An appropriate rated and pre-approved me-
lag fuse must be used to prevent unnecessary fuse failure during pump start-up (in
accordance with local and regional electrical codes). Within ve minutes, as the oil in the
pump warms up, the current drawn will slowly reduce to the full load current specied
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 -904).
