Technical Data - EBARA HERTZ ONE Manual

3. WARNINGS
Read these instructions carefully before proceeding with the installation.
The electrical system and connections must be made by qualified personnel according to the safety
regulations pertaining to the installation and maintenance of technical systems in force in the country
where the product is installed.
In addition to generating dangers for personal safety and damage to the equipment, failure to comply
with the safety regulations will result in the invalidation of all service coverage under the warranty.
By qualified personnel we mean those people who, possessing the required training, experience and
skills, as well as knowledge of the pertinent regulations, provisions and prescriptions regarding
accident prevention and operating conditions, have been authorized by the plant safety supervisor to
carry out any activity aimed at preventing safety hazards. (IEC 364 definition for technical personnel).
Make sure that the HERTZ ONE and the unit have not suffered any damage during transportation or
storage. In particular, make sure that the external casing is undamaged and in perfect conditions. All the
internal parts of the HERTZ ONE (components, wires, etc) must be completely free of humidity, oxides or
dirt: if this is not so, carefully clean all components within the HERTZ ONE and ensure they are working
correctly and if they are not, replace them. It is of the utmost importance that all HERTZ ONE wires are
correctly tightened in their terminals. In the event of long storage (or replacement of any of the
components) all the tests specified by EN standard 60204-1 should be conducted on the HERTZ ONE.
READ THE PLATE INSIDE THE HERTZ ONE CAREFULLY.
Disconnect the HERTZ ONE from the mains power supply and wait 3 minutes before performing any
work inside the electrical panel.
