Understanding the power unit topology
Figure 14 shows the principles for mains and motor connections of ATV780C20 to ATV780C71.
ATV78C50 has double input devices and requires an even number of supply cables but an uneven
number of motor cables can be used. ATV780C56 to ATV780C71 consist of two power modules and
require an even number of supply and motor cables. See Figure 14 and Table 12.

Mains and motor cables
The mains cables are connected to terminals L1, L2 and L3 and the motor cables to terminals
marked with U, V and W, see Figure 8.
In ATV780C50Y to ATV780C71Y an even number of input cables is required. In converters consisting
of double power modules (FR12) an even number of input cables and an even number of motor
cables is needed.
WARNING
WARNING
In types with double inputs (ATV780C50Y to ATV780C71Y) or outputs (ATV780C56Y to
ATV780C71Y) is it very important that the same cable dimensions, type and routing is used
for all cables. In case the cabling between the converter modules is not symmetrical,
unequal load inside converter might reduce loadability or even damage the converter.
In units with double motor outputs the motor cables must not be connected together in the
converter end. Always connect the parallel motor cables together in the motor end only.
The minimum motor cable length is 5m.
The output cables to the motor must be 360o EMC earthed. The EMC grounding clamps can, for
instance, be installed on the mounting plate in front of the AC choke as shown in the figure below.
The EMC grounding clamps must be suited to the output cable diameter to give a 360o contact with
the cables.

PREPARING FOR EXTERNAL POWER CONNECTIONS

As a rule of thumb, cables and the fuses can be dimensioned according to the frequency converter
nominal OUTPUT current which you can find on the rating plate. Dimensioning according to the
output current is recommended because the frequency converter input current never significantly
exceeds the output current.
Table 12 shows the minimum dimensions of Cu- and Al-cables and the recommended aR fuse sizes.
If the motor temperature protection of the drive (see the Programming Manual, on the CD) is used
as an overload protection, the cable should be chosen accordingly. If three or more cables are used
in parallel (per block) in bigger units each cable requires a separate overload protection.

CONTROL OF MAIN AIR FLOW
CAUTION! It is of utmost importance for the operation and lifetime of the frequency converter
that the enclosure is well ventilated to keep the temperature below the maximum
operating temperature. Repeated overheating will shorten the lifetime of the
converter.
9.1
Arranging ventilation of the enclosure
The enclosure door must be provided with air gaps for air
intake. To achieve sufficient cooling inside the cabinet, the
dimensions for the total area of free openings for
incoming air given in Table 9 must be followed. For
instance, there could be two screened gaps as presented in
Figure 0 (Manufacturer’s recommendation). This layout
ensures a sufficient air flow to the module fans as well as
cooling of the additional components.
2
Air outlet gaps must be situated on top of the cabinet. The
minimum effective air outlet area per converter frame is
given in Table 9.The cooling arrangements inside the cabinet
must be such that they prevent hot output air from mixing
with the incoming fresh air (see page 21 below). The
ventilation gaps must fulfil the requirements set by the
selected IP class. The examples in this manual apply to
protection class IP21.
During operation, air is sucked in and circulated by a fan
blower at the bottom of the power unit. If the power unit is
placed in the upper part of the cabinet, the fan blower will be
in the mid of the cabinet, at the height of the upper
ventilation grid.

Steering the internal air flow
Cooling air must be sucked in through the ventilation gaps on the door and blown out at the top of
the enclosure. To steer the hot air from the power unit to the outlet at the top of the enclosure and
prevent it from circulating back to the fan blower, use either of the following arrangements:
A.
Install a closed air duct from the power unit to the outlet on top of the enclosure (A in
the figure below).
B.
Install shields in the gaps between the power unit and the cabinet walls (B in the
figure below). Place the shields above the air outlet gaps at the sides of the module.
In ATV780C56Y to ATV780C71Y, close the opposing gaps in the upper part of the
cabinets with a sheet metal plate to ensure proper cooling.

Control of main air flow
NOTE!
To allow free air circulation, the touch cover at the bottom of the cabinet must be of type
meshed sheet metal screen. For the same reason, the busbar touch protection cover and
the choke upper support must be equipped with holes. See Figure 17.
NOTE!
If a flat roof is used, mount a V-shaped air guide on the underside of the roof to direct the
air flow horizontally. See Figure 18.

Heat dissipation
The efficiency of the frequency converter is a function of switching frequency, operating frequency
and load (see User’s manual). Based on this information, heat dissipation can be calculated at a
certain operating point. For most cases the following general formula based on frequency converter
load can be used to estimate the heat dissipation of the power module:
Ploss [kW ] = Pmot [kW ]* 0.025
The following table shows the heat dissipation from the AC choke.
