Epsilon
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.

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.
Identification of Safety Information
Safety related information through out this manual is identified with the following markings.
“Warning” indicates a potentially hazardous situation that, if not avoided, could result in death or serious injury.
“Caution” indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate injury.
“Caution” used without the safety alert symbol indicates a potentially hazardous situation that, if not avoided, may result in property damage.
Note
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
