to connect the protection earth, ensure that this is correctly installed before
powering up the input to the equipment.
• The installation of UPS equipment should only be carried out by qualified
personnel experienced in low voltage installations.
• The cross section of the power supply and output cables to the loads should
be determined according to the rated current given on the equipment’s
specifications plate and complying with the local low voltage electro technical
regulations.
• The power supply cables to the equipment as well as to the loads, interfaces,
etc. should be fixed to non-movable parts.
• The neutral cable must be connected only with the clamp provided. Note that
all neutral cables for input, output and the center tap of the battery inside the
UPS are connected together. The UPS works without a transformer. A leakage
current of 160 mA can occur.
3. Safety interactions for battery equipped products
• A UPS is a continuous power supply equipment. If the mains supply fails while
the equipment is operating, the output lines will continue to supply output
voltage depending on the autonomy times provided by the batteries.
• The 10 – 40 kVA UPS can be delivered with built in batteries. Optionally
batteries can be delivered separately and then installed at your location by
authorized personnel.
• For proper operation the battery cabinet must be located beside the machine.
• The battery supply can involve the risk of electric shock and can produce high
short circuit current. Observe the following preventive measures before
manipulating any terminal block identified in the labeling as “Battery”.
- Disconnect the corresponding protection elements.
- When connecting a battery cabinet with the equipment, respect the cable’s
polarity and color (red-positive; black-negative) indicated in the manual and in
the corresponding labeling.
- Wear rubber gloves and shoes.
- Use tools with insulted handles.
- Removes watches, rings or other metal objects.
- Do not place metal tools or objects on the batteries.
- Never manipulate with your hands through conducting objects, do not short
the battery terminal block or the battery enclosure.
