• Whether the HZI855 is sold as a loose product, as a spare, in a kit or as part of an enclosed solution
or in any other configuration, this device must always be installed and commissioned by qualified and
experienced personnel, in line with the manufacturers recommendations, following good engineering
practices and after having read and understood the details in the latest release of the relative product
instruction manual.
• Maintenance on the product and any other associated equipment including but not limited to servicing
operations must be performed by adequately trained and qualified personnel.
• Each product is shipped with a label or other form of marking including rating and other important
specific product information. One must also refer to and respect markings on the product prior to
installation and commissioning for values and limits specific to that product.
• Using the product outside the intended scope, outside Hager recommendations or outside the
specified the specified ratings and limits can cause personal injury and/or damage to equipment.
• This instruction manual must be made accessible so as to be easily available to anyone who may
need to read it in relation to the use, installation or maintenance of the HZI855.
• The HZI855 meets the requirement for the IEC 60947-6-1 standard for transfer switching equipment
and the IEC 61010-2-201 standard for control equipment; the product includes the labels and marking
with details on each standard.
• No covers on the HZI855 should be opened (with or without voltage) as there may still be dangerous
voltages inside the product such as those from external circuits.
•
Do not handle any control or power cables connected to the HZI855 when voltages may be
present on the product directly through the mains or indirectly through external circuits.
• Voltages associated with this product may cause injury, electric shock, burns or death. Prior to
carrying out any maintenance or other actions on live parts in the vicinity of exposed live parts, ensure
that the switch including all control and associated circuits are de-energized.
2. Standards
• HZI855 complies with the following international standards:
- IEC 60947-6-1 - Transfer switching equipment
- IEC 61010-2-201 - Control equipment
- IEC 61010-1 - Electrical safety requirements
- Annex C of GB/T 14048.11
3. Introduction
HZI855 is compliant to international product standards and is designed specifically for use in low
voltage power applications to ensure the safe transfer of a load supply between a normal and an
alternate source.
