4.1.15 Mounting
There are two options for mounting the Line Filter
correctly:
1. Front mounting
•
Mount the filter in a vertical position with the
terminals at the bottom.
•
Mount the frequency converter on the front of
the Line Filter using 3 M4 bolts.

•
Ensure metal-to-metal contact between filter and
frequency converter.
NOTE
Metal-to-metal contact improves EMC performance and
enables the baseplate of the frequency converter to
function as heatsink for the Line Filter
2. Side mounting
•
Mount the filter side-by-side with the frequency
converter.
There is no requirement for spacing between
filter and frequency converter.
•
Mount the back of the Line Filter to a cooling
surface, such as a metal wall. Alternatively, derate
the Line Filter by one size: For example use a
0.75 kW Line Filter with a 0.37 kW Micro Drive.
CAUTION
High temperatures
Risk of fire or device damage
•
Do not mount the Line Filter in close proximity to
other heating elements or heat-sensitive material
(such as wood).
4.1.16 Wiring
WARNING
Risk of electrical shock due to high leakage currents
•
Do not power up the Line Filter before it is
connected to protective earth (PE)
1.
Connect Line Filter to protective earth (PE). Use a
cabinet mounting panel or similar to achieve
optimum earthing conditions.
2.
Connect input terminal to mains power (cable
not supplied)
3.
Connect output cable to the input terminals of
the frequency converter
4.
Ensure solid electrical contact between Line Filter
and frequency converter (high frequency
earthing)
