Filter placement and mounting
Lift the heavy reactors which have lifting eyes (>25kg) with appropriate lifting aids –smaller types may
be lifted
manually by two persons.
RWK 3044 /RWK 3062 AC line reactor are 3-phase devices
and must be positioned and wired in series
to the input side of the VFD (Variable Frequency Drives). All terminals are marked. L1, L2, and L3 are
the input terminals, which should be connected to the grid side.
L1’, L2’, and L3’ must be connected to
the motor drive input side.
The mounting of RWK3044/RWK3062 shall be made on a metal plate which has a
reliable protective earth
(PE) connection.
Always connect RWK3044/RWK3062 to the protective earth (PE) first, and then
continue with the wiring of line terminals. When decommissioning the
RWK3044/RWK3062 remove the PE connection at the end.
RWK3044/RWK3062 reactors can reach surface temperatures up to 175°C when driven
under maximum allowed load. Avoid burnings by waiting long enough after that the
application is switched off.

Ambient temperature and clearance
RWK3044 and RWK3062 shall be installed where the ambient temperature does not exceed 45°C. Do
not locate the reactor next to any other component with operating surface temperature above
125°C.
RWK3044 and RWK3062 reactors can be used to a maximum altitude of 2000m without derating, and
with derating (current and voltage) above 2000m according to IEC 60664-1.
RWK3044/RWK3062 reactors are designed to be floor-mounted or wall-mounted. In principle,
the reactors shall be mounted vertically to respect a proper heat dissipation flow. To ensure an
optimal ventilation and thermal radiation, it is recommended to leave enough space towards
surrounding equipment, walls or components in all directions.
For floor-mounting, clearance above the filter of >150mm and >50mm aside is required.
For wall-mounting, clearance above and below the filter of >150mm and >50mm aside is
required.
The recommended, permitted and prohibited mounting positions are shown in Figure 2 to Figure 5. The
mounting on a vertical plate is limited to products with a maximum weight of 25kg. Larger reactors
must be mounted in a horizontal position.

Use all available mounting holes
and select the correct screws and washers (more information please
refer to the product datasheet) in order to ensure a reliable mounting and take into account
the weight
of these products. Apply torques appropriate for the strength class of the screws and
washers you are
using. Specifications can be obtained from the supplier of the screws and washers.
