Power wiring

Standard connection

Supply voltage must be connected to the terminals

X1.1, X1.2 and X1.3. The adjustable frequency drive

supply terminals L1, L2, and L3 must be connected to

the filter module terminals X2.1, X2.2, and X2.3.

Paralleling of AFDs

If several adjustable frequency drives are to be

connected to the harmonic filter, the connection

is similar to the standard connection - The supply

terminals L1, L2 and L3 of several adjustable

frequency drives must be connected to the filter

module terminals X2.1, X2.2 and X2.3.

NOTE

If several AFDs are to be connected to

the same filter, the harmonic filter must

be sized according to the sum of the

calculated input current to the AFDs.

Paralleling of filters

If the line input current of the adjustable frequency drive

exceeds the nominal current of the largest harmonic

filter, several harmonic filters can be paralleled to

achieve the necessary rating. Supply voltage must

be connected to the terminals X1.1, X1.2 and X1.3

of the filters. The adjustable frequency drive supply

terminals L1, L2 and L3 must be connected to the

filter modules terminals X2.1, X2.2 and X2.3.

NOTE

Filters of different current ratings can be

paralleled. The rating of the filter becomes the

sum of the individual current ratings.

Capacitor disconnect

The power factor of the harmonic filter AHF 005/010

decreases with decreasing load. At zero load, the

power factor becomes zero and the capacitors produce

approximately 30% leading current compared to the

rated current of the filter. The reactive current generated

by the filter at partial load is normally not of any concern,

mainly because of the small current compared to the

system capacity (max 30%) as well as the fact that other

load normally compensates the capacitive current.

In applications where this reactive current may not be

accepted, Terminals X3.1, X3.2, X3.3 and X4.1, X4,

X4.3 give access to the filter capacitors. By default

(on delivery), the wiring will shorten Terminal X3.1

with X4.1, X3.2 with X4.2 and X3.3 with X.4.3. In

the case that no capacitor disconnect is required, no

changes should be made. If capacitor disconnect

is required, a three-phase contactor should be

placed between terminals X3 and X4. Size the

contactor and wiring to 50% of the nominal current

and use the AC3 rating of the contactor

NOTE

Only switch the contactor at less than 20% load.

Allow minimum 5 minutes for the capacitors

to discharge before turning on again.

Use cables complying with local regulations.
