Electrical data
Supply voltage and frequency
UPS, USA: 115, 208-230 V, 1 phase 60 Hz,
208-230, 460, 575V, 3 phase 60 Hz.
Motor protection: The pump requires no external motor
protection if the motor is fitted with a protection
module.
Back-up fuse: Max. 10 A.
Electrical Connection
The electrical connection and protection should be
carried out in accordance with the latest edition of the
National Electrical Code, local codes and regulations by
a qualified electrician.
Warning: Never make any connections in the pump
terminal box unless the electrical supply has been
switched off.
• The pump must be grounded
• The pump must be connected to an external main
power switch.
The operating voltage and frequency are marked on the
pump nameplate. Make sure that the motor is suitable
for the electrical supply it is being installed to.
The pump should be grounded to protect against indi-
rect contact and a ground fault interrupter can be used
as extra protection.
Multi-Speed Pump (1 & 3 phase)
All single and 3 phase pumps are equipped with built-in,
automatic resetting, thermal overload protection at all
three speeds.
Two-Speed Pump (3 phase, 3X460V & 575V)
The pump must be connected to the electrical supply via
an external contactor. The contactor must be connected
to the built in thermal overload switch terminals P1 and
P2 (3x460V & 575V) to protect the pump against over-
loading at both speeds.
OR: If the pump is protected by means of a motor starter,
the starter must be set to the current consumption of
the pump at the selected speed. The motor starter
setting must be changed every time the pump speed is
changed. The current consumption at the individual
speeds is stated on the pump nameplate.
Protection module (standard)
The pump is connected directly to line voltage, as the
pump features built-in protection against overheating
at all three speeds.
The figure below shows the electrical connection of
single-phase and three-phase pumps.
*Except 460, 575 Volt
Relay module
The pump is connected directly to line voltage as it incor-
porates protection against overheating at all three
speeds.
The relay module has a signal output for an external
operating or fault signal device. By means of the selector
switch the signal output can be used as operation or
fault signal output:
