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 -904)
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
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
Table: Electrical data (single-phase pumps with Part Numbers
for up to several seconds. An appropriate rated and pre-approved time-
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
