Installation and Connection

3.2 Good EMC Installation Techniques

1) Mount the COMBIVERT F5 on a conductive

(zinc or nickel plated not painted) subpanel.

This sub plate serves as the central grounding

point for the machine.

2) Always connect the shield of motor and

control cables with maximum surface area,

use a metal cable clamp to contact cable

shield on all sides. Using a single strand of

the shield or the drain wire from the shield

as the only connection can reduce the

shield’s effectiveness by 70%.

3) The distance between control and power

cables should be at least 10..20 cm / 4...8

inches.

4) Keep the motor and power cable spatially

separated especially if running parallel.

5) If it cannot be avoided, cross control and

power cables and motor cables at a right

angle.

6) Install all cables as close as possible to the

mounting plate - ideally in a metal wireway.

7) Ridged metal conduit can be used as a

shield for the motor cables. Always observe

the following points:

• Remove all paint from the control panel where the conduit is to be secured.

• Securely fasten all conduit fittings.

• Run only the motor wires through the conduit. All other wires must be pulled

through a separate conduit.

• Connect the control panel to the sub panel with a heavy ground strap.

8) If a KEB EMI (CE) filter is used, it must be mounted as close as possible and to the

same subpanel as the COMBIVERT F5 motor control. The filter must have large bare

surface contact with the subpanel. Use only the wires from the filter to connect to the

inverter. Never add additional lengths of wire.

9) All ground connections should be as short as possible. Always avoid creating ground

loops. NEC requires a ground conductor connected to every COMBIVERT F5 controller

in spite of the metal on metal connection to the subpanel.
