1.7 - ELECTRICAL CONNECTION
• All electrical connections are to be realized by qualified skilled personnel only.
• In this manual "Earth" is represented with two different symbols:
= Field wiring equipment grounding terminal,
= Grounding terminals.
• The UPS should only be powered from a single phase, three wire AC source equipped with an earth connection.
• Use insulated copper input and output wiring, rated 90°C (194°F) wire size based on the capacities given in Tables
310-16 of the Nation Electrical code, ANSI/NFPA 70-2008. Specified in table 2 and table 3.
• When working on live Uninterruptible Power Supplies, be sure to comply with the applicable national accident
prevention rules.
1.8 - OPERATION
DANGER, do not touch output terminals.
The UPS is connected to batteries. The output terminals may be electrically live, even when the UPS is
disconnected from the utility supply. Dangerous voltages may be present during battery operation.
1.9 - MAINTENANCE AND SERVICING
• All maintenance and servicing is to be carried out by qualified skilled personnel only
• Servicing of batteries should be performed or supervised by personnel knowledgeable of batteries and the required
precautions. Keep unauthorized personnel away from batteries
• A battery can present a risk of electrical shock and high short circuit current
• Never dispose of batteries in a fire: they may explode
• Do not open or mutilate batteries: their contents may be extremely toxic. If exposed to electrolyte, wash immediately
with plenty of water
• The batteries must be disconnected during maintenance or service work.
• When replacing the batteries, use only the same type and size battery.
• The following precautions should be observed when working on batteries:
- Remove watches, rings or other metal objects.
- Use tools with insulated handles.
- Wear rubber gloves and boots.
- Do not lay tools or metal parts on top of batteries.
- Disconnect charging source prior to connecting or disconnect battery terminals.
- Determine if the battery is inadvertently grounded. If inadvertently grounded, remove source of ground. Contact
with any part of a grounded battery can result in electrical shock. The likelihood of such shock will be reduced if
such grounds are removed during installation and maintenance.
The batteries contain lead, which is a harmful substance for the environment.
Proper disposal or recycling of the batteries is required. Refer to your local codes for disposal
requirements.
