Specification
For the purpose of this manual and product, “Note” indicates essential information about the product or the
respective part of the manual.
Throughout this manual, the word “drive” refers to an Epsilon EP drive.
“Caution” used without the safety alert symbol indicates a potentially hazardous situation that, if not avoided,
may result in property damage.
General warning
Failure to follow safe installation guidelines can cause death or serious injury. The voltages used in this unit can
cause severe electric shock and/or burns, and could be lethal. Extreme care is necessary at all times when
working with or adjacent to this equipment. The installation must comply with all relevant safety legislation in the
country of use.
Supply isolation device
The AC supply or high voltage DC supply must be removed from the drive using an approved isolation device or
disconnect before any servicing work is performed, other than adjustments to the settings or parameters
specified in the manual. The drive contains capacitors which remain charged to a potentially lethal voltage after
the supply has been removed. Allow at least 6 minutes for Epsilon EP206 and 3 minutes for Epsilon EP202/204
after removing the supply before carrying out any work which may involve contact with electrical connections to
the drive.
Products connected by plug and socket
A special hazard may exist where the drive is incorporated into a product which is connected to the AC supply by
a plug and socket. When unplugged, the pins of the plug may be connected to the drive input, which is only
separated from the charge stored in the bus capacitor by semiconductor devices. To avoid any possibility of
electric shock from the pins, if they are accessible, a means must be provided for automatically disconnecting the
plug from the drive (e.g., a latching contactor).
Grounding (Earthing, equipotential bonding) - High Leakage Current
The drive must be grounded by a conductor sufficient to carry all possible fault current in the event of a fault. This
equipment has high earth leakage current. You must comply with local safety regulations with respect to
minimum size and special installation requirements on the protective earth conductor for high leakage current
equipment. The ground connections shown in the manual must be followed.
Fuses
Fuses or over-current protection must be provided at the input in accordance with the instructions in the manual.
Isolation of control circuits
The installer must ensure that the external control circuits are isolated from human contact by at least one layer
of insulation rated for use at the applied AC supply voltage. External control circuits identified as PELV circuits do
not need this isolation when they are completely within a zone of equipotential bonding, generally within a single
enclosure or group of enclosures bonded together.
