1. SAFETY STANDARDS
WARNING!
This is a product for commercial and industrial applications in an industrial environment – installation restrictions
or additional measures may be needed to prevent interference.
CAUTION IF DAMAGED
NON-SPILLABLE BATTERIES
Torn, crushed or damaged packaging which exposes the contents should be set aside in an isolated area and
inspected by a qualified person. If the package cannot be shipped the contents must be promptly collected, segre-
gated, and either the sender or recipient contacted.
All packaging material must be recycled in compliance with the laws in force in the country where the system is installed.
1.1.1. Only for ITYS 1-3 kVA
• Since the UPS power cord functions as an isolating device, ensure ready access to the mains power socket where the UPS is
connected, and/or the rear panel of the UPS, so the unit can be easily unplugged.
• The UPS generates a leakage current of approximately 3 mA. To guarantee the maximum leakage current of 3.5 mA, ensure the
leakage current generated by the load is no greater than 0.5 mA. Should the leakage current from the load exceed this limit, instruct
a skilled engineer to install an industrial type connection (to IEC 309 standard) between the UPS and the a.c. mains supply, sized
to handle a current compatible with the rating of the appliance.
1.1.2. Only for ITYS 6-10 kVA
If the UPS does not have an automatic protection device against
current back feed, the operator/installer must:
- add warning labels to all the mains power disconnecting switches
installed at a distance from the UPS area; this serves to remind
technicians of the fact that the circuit is connected to a UPS.
- install an external isolating device as shown in figure.
ISOLATE THE UPS BEFORE
