between 59°F and 77°F (+15°C and +25°C).
2. Provide protection against moisture or avoid altogether if possible.
3. Ensure there is at least 4 inches (100mm) behind and 2 inches (50mm) on each side of the
UPS for ventilation.
4. Ensure that the front of the UPS remains unobstructed for access to the control panel and
LCD display.
5. External Battery Packs must be installed next to or under the UPS.
5.2 AC Power and Load Connections
Vertical and Wall-Mount Installation
Only qualified technicians should carry out installation of this equipment. The installation must
further comply with all local legislation and regulations.
Follow all installation and safety instructions very carefully to avoid the existence of a hazardous
situation and damage to the UPS and/or loads.
The high voltage and current contained within this equipment can injure or be fatal to
personnel and can damage associated equipment.
Various input (and sometimes output) cables are supplied with all models:
1. Ensure that the UPS is disconnected from the AC supply when connecting External Battery
Packs.
2. Use the battery cable that is supplied with the External Battery Pack when connecting it to the
UPS. Connect the second battery cabinet to the first and so forth, assuming more than one is
to be used.
3. Take note of UPS parameters when adding external battery packs and adjust accordingly
(see Ch. 7).
4. Connect the input cable to the UPS and connect the other end to a grounded AC power
supply. The batteries will automatically begin to charge. Please note that while the UPS may
be used immediately, maximum back-up time may not be available until the batteries have
been charged for a minimum of 8 hours. See Table 1 for input circuit breaker rating and
conductor size.
5. If the unit displays "Site Wiring Fault", have the wiring fault corrected or alternately, disable the
related alarm on the UPS.
6. After initial charging is complete, connect the loads to the UPS.
7. Do not connect any load that may overload the UPS such as equipment containing AC electric
motors or loads that have a high inrush current.
8. Make computer and/or alarm interface connections according to Chapter 6 of this user manual
and that provided with the interface option. These connections are made on the rear panel.
9. Installation is now complete.
