ELECTRICAL SHOCK HAZARD
Due to the stray capacitance of the shielded motor cable, the leakage currents exceed 3.5 mA. Failure to connect the drive or filter
properly to protective earth may result in death or serious injury.
Ensure minimum size of the ground conductor complies with the local safety regulations for high touch current equipment.
Ensure reinforced protective earthing (PE) conductor according to IEC 60364-5-54 cl. 543.7 or local safety regulations for
equipment with leakage current >3.5 mA.
The reinforced protective earthing can be done with:
PE conductor with a cross-section of at least 10 mm
2
(8 AWG) Cu or 16 mm
2
(6 AWG) Al, or an additional PE conductor of the
same cross-sectional area as the original PE conductor as specified by IEC 60364-5-54, with a minimum cross-sectional area
of 2.5 mm
2
(14 AWG) mechanically protected or 4 mm
2
(12 AWG) not mechanically protected.
PE conductor completely enclosed within an enclosure or otherwise protected throughout its length against mechanical
damage.
PE conductor that is part of a multi-conductor power cable with a minimum PE conductor cross-section of 2.5 mm
2
(14 AWG)
that is permanently connected or plugged in by an industrial connector. The multi-conductor power cable must be installed
with an appropriate strain relief.

INTERNAL FAILURE HAZARD
An internal failure in the filter can result in serious injury when the filter cover is not properly secured.
Ensure that all safety covers are in place and securely fastened before applying power.

BURN HAZARD
The IP00/Open Type filter model (S1C02–S1C08) does not have protective covers over all components that may still be hot even
after the unit has been powered off. Failure to avoid touching these components can result in serious burns.
Install the IP00/Open Type filter in an enclosed cabinet.
Do not touch exterior areas that are marked by the high temperature symbol (yellow triangle). These areas are hot while the
drive and filter are in use and immediately after being powered off.

ELECTRIC SHOCK
The IP00/Open Type filter model (S1C02–S1C08) does not have protective covers over all high-voltage components. Failure to
avoid touching these components can result in death or serious injury.
Install the IP00/Open Type filter inside a supplementary enclosure or in a restricted-access area that provides protection
against electric shock.
1.5 Required Tools
Lifting aid
Tape measurer
Wrench with extension and various sockets (see the wiring illustrations for the specific size)
Torx, slotted, and Pozidrive screwdrivers (T20, T30, T50, SL1.2, SL2, PZ3)
Wire crimper
1.6 Verifying the Shipment and the Contents
Make sure that the items supplied and the information on the product label correspond to the order confirmation. The product
label is found on the front of the filter.
