Power supply connection
The pump can be connected to the power supply in
different ways, depending on the model.
Pumps above 140 W power consumption (UPMXL,
UPMXXL) are supplied with mounted short high-
temperature resistant cables with external NTC box
plus different adapters for MOLEX, VOLEX or TE
Superseal supply cables to reduce the inrush level to
the specified one.

Alternative pumps are available with mounted power
cables (1 m and 2 m) with NTC but without connector.
Pumps up to 140 W power consumption have
integrated NTC to reduce to the specified inrush level
of the chosen variant. These pumps can be delivered
with mounted plug connector like MOLEX, VOLEX or
TE Superseal. An additional NTC adapter cable can
reduce the inrush level additional by approx. 4 A.
Note: All cables and connectors used must comply
with EN 60335-1.
Signal cable
Medium UPM AUTO pumps are internally speed-
controlled and have no signal cable connection. We
recommend to order these pump types with signal
blind plug. Medium UPM PWM/LIN pumps are
externally speed-controlled. To enable pump control, a
signal cable is required, otherwise the pump always
runs at maximum speed (profile A for heating).
The signal cable has three leads, signal input, signal
output and signal reference. The cable must be
connected to the control box by a Dubox housing with
a FCI terminal block and terminals. The optional signal
cable can be supplied with the pump as an accessory.
The cable length is customised to specific
requirements (maximum 3 metres).
The installation of a ferrite core around the cable is not
necessary.

SOLAR PML pumps do not run without
signal (PWM profile C for solar).
Connect the signal wires to the correct
poles. Otherwise the pump might be
damaged.
