Hazardous voltage may be present.
Always isolate the electrical power supply before making or changing
connections to the unit.
In case of the usage of an inadequate AC/DC power supply, mains
voltages may be present (even if the system is designed for 48VDC).
The usage of a galvanic separated power supply, which is certified by a
3
rd
party (UL or CE), is highly recommended.
Hazardous voltage may be present.
The controller housing must be properly grounded and placed in a spill
protected electrical cabinet. Use one of the DIN-rail screws on the back
side of the controller housing.
Do not use different and longer screws, which may result in short-circuit
within the controller.
1. The controller casing must be grounded. The screws of the DIN-rail brackets can be used for grounding (see
Figure 26).
2. Connect the two motor connectors (“Power Output” and “Sensoric”) to the controller.
3. Connect the controller type specific connectors: see Section 4.1.3 for standalone operation with the LPC-600.1,
Section 4.1.4 for extended operation with LPC-600.1 and Section 4.1.5 for extended operation with LPC-600.2.
4. The pump system requires 48 DC supply voltage at a maximum power of 600 W. At a lower performance power
supplies with smaller power or bigger supplies to supply several pump systems simultaneously may be used.
Consult Figure 14 to get the power consumption depending on the flow. Contact Levitronix for consulting and
support on the power supply solution.
5. Connect the DC power supply connector with the cable (included in the controller delivery). Make sure that the
polarity is correct (see Figure 24 and Figure 25) and that AC/DC power supply is off.
6. To secure the connectors, tighten all retaining screws according to the torque specifications in Table 9 for LPC-
600.1 and Table 10 for LPC-600.2 controller.
