Technical data
2.3 Mechanical data
2.4 Electrical data: single-phase motor
When you start a cold pump, the motor draws the start-up current shown in Table 1 for less than one second. To
prevent unnecessary fuse failure during start-up use a slow-blow fuse. Within five minutes, as the oil in the pump
warms up, the start-up current reduces to the full-load current specified in Table 1.
2.5 Electrical data: three-phase motors
Refer to the data in Table 2. You can configure the dual voltage motors to operate with either the high range or low
range electrical supply: refer to the diagram specified in Table 2. Dual voltage motors are supplied preset to the
highest of the selectable voltages.
When you start a cold pump, the motor draws the start-up current listed in Table 2 for less than one second. Within
five minutes, as the oil in the pump warms up, the current drawn slowly reduces to the full-load current specified in
Table 2.
When you restart a hot pump, the motor draws the start-up current specified in Table 2 for up to 0.5 seconds. The
current drawn then immediately falls to the full-load current value.
