1. Overview
For use in the most critical applications, these models are true on-line, double conversion designs
that provide a continuous, true sine-wave output with less than 3% total harmonic distortion
(THD). They allow for a wide input voltage range of +-27% and also feature power factor correction
and dual microprocessors for control of all functions.
Unique features include a ‘cold-start’ function that allows the user to power up the load(s) directly
from the UPS without the presence of utility power, a multi-function LCD display and cooling fans
that vary their speed relative to load size.
Independent input and output fuses and circuit breakers protect against overload and shortcircuits and advanced battery management extends battery life by up to 50%. 2000VA and 3000VA,
120V models also come with hard-wire terminal blocks for permanent installation.
Using the UPS with the included software and interconnecting cable allows intelligent control
of the system when linked to a host computer. (Some operating systems may require the use
of other optional software). In addition to the RS-232 function of the communication port, solid
state signalling and remote control of basic UPS functions is available.
When an overload or malfunction occurs, the UPS automatically and seamlessly transfers to bypass
mode and continues to supply the load with utility power. Upon removal of the fault condition, the
unit automatically transfers back to inverter mode once the unit has been restarted.

EMC Statements
FCC Part 15
NOTICE: Pursuant to section 15 of the FCC rules, this product has been tested and thereby complies
with the conditions of a Class B (700-2000VA) and Class A (3000VA) digital device, which have been
established for offering sufficient protection against dangerous interference for installation in a
residential area. Installation and use of the equipment should comply with the instructions provided in
order to avoid such interference due to the amount of radio frequency energy that is radiated and
generated by the equipment. In spite of this, we cannot assure that a certain amount of interference may
not occur in some installations. If, by turning on and off, it can be deduced that your radio or television
reception is found to be influenced by harmful interference from the equipment, it is recommended that
one of the following preventive measures be used:
1. Place the receiving antenna in a separate location or orientation.
2. Ensure a greater distance is achieved between the receiver and the equipment.
3. Ensure that your equipment is connected to an outlet on a separate circuit than the receiver.
4. Contact a technician experienced with radio and TV or call tech support for further assistance.

Maintenance of the UPS and Batteries.
2. The equipment can be operated by any individual. No previous experience is required.
3. CAUTION (UPS with Internal Batteries): Risk of electric shock - Hazardous live parts inside
this unit are energized from the battery supply even when the input AC power is disconnected.
Refer to top, rear and/or underside of the unit for cautionary markings.
4. CAUTION (No User Serviceable Parts): Risk of electric shock, do not remove cover. No user
serviceable parts inside. Refer servicing to qualified service personnel.
5. CAUTION (Non-isolated Battery Supply): Risk of electric shock, battery circuit is not isolated
from AC input; hazardous voltage may exist between battery terminals and ground. Test before
touching. Do not disconnect battery connector/s under load.
6. WARNING (Fuses): To reduce the risk of fire, replace only with the same type and rating of fuse.
7. CAUTION (Live Heat Sink): Risk of electric shock - heatsink is live. Disconnect unit prior to servicing.
8. WARNING (Controlled Environment): Intended for installation in a controlled environment.
The maximum ambient temperature is
9. CAUTION: When replacing batteries, replace with the same type and number of batteries:
One Sealed lead acid battery, rated 12 V, 8.5 Ah max. Do not touch uninsulted battery terminals
10. ATTENTION (Electric Shock Hazard): Even when the unit is disconnected from the AC supply,
hazardous voltage may still exist via the battery supply. The battery supply should be disconnected
at the positive and negative termianls when the UPS needs to be serviced or the batteries replaced.
77°F / 25°C.
11. CAUTION: Do not dispose of batteries in a fire, as they may explode.
12. CAUTION: Do not open or damage the battery, electrolyte may be released which is harmful to
the skin and eyes.
13. CAUTION: A battery can present a risk of electric shock and high short circuit current.
The following precautions should be taken when working with batteries:
a. Remove watches, rings and other jewelry or metal objects.
b. Use only tools with insulated handles.
c. Wear rubber gloves and boots.
d. Do not lay tools or metal parts on top of batteries.
e. Disconnect charging source prior to connecting or disconnecting battery terminals.
14. To reduce the risk of electric shock, disconnect the UPS from the AC input power supply
before installing a communication interface cable. Reconnect the power cord only after
communication interconnections have been made.
15. Battery replacement should be performed or supervised by personnel with knowledge of
batteries. Keep unauthorized personnel away from the batteries.
16. CAUTION: To reduce risk of fire, use only No. 26 AWG or larger telecommunication line cord.
17. CAUTION (High Leakage Current - Ground Connection Essential): The total leakage current
for the UPS and any connected equipment shall not exceed 3.5 mA.
18. CAUTION (Size of Branch Circuit Over-current Protection): To reduce risk of fire, connect only
to a circuit capable of 35 amperes (2000VA models) and 50 amperes (3000VA models) maximum
branch circuit over-current protection in accordance with National Electric Code, ANSI/NFPA 70.
19. CAUTION (For Models with I/P Terminal Block): For 800 - 1500VA models: Use No. 10 AWG
type TW cable, trade size 3/4 in. conduit, 60°C, copper wire for input an output field wiring. For
2000/3000VA models: Use No. 8 AWG type TW cable, trade size 3/4 in. conduit, 60°C, copper
wire for input/output field wiring. Use tightening torque of 29 ft.-lbs./40Nm to secure wiring to block.
