IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
1. This Manual Contains Important Instructions that should be followed during Installation and
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.
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 Batte ry 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.
6. WARNING (Fuses): To reduce the risk of fire, replace only with the same type and rating of fuse.
7. WARNING: Intended for installation in a controlled environment. The maximum ambient
temperature is 40°C.
8. CAUTION: When replacing batteries, replace with the same type and number of batteries:
9. CA
UTION: Do not dispose of batteries in a fire, as they may explode.
10. CAUTION: Do not open or damage the battery, electrolyte may be released which is harmful to
the skin and eyes.
11. 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.
12. 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.
13. Battery replacement should be performed or supervised by personnel with knowledge of
batteries. Keep unauthorized personnel away from the batteries.
14. CAUTION: To reduce risk of fire, use only No. 26 AWG or larger telecommunication line cord.
15. CAUTION (For 700-2000VA Models Only): To reduce risk of fire, connect only to a circuit provided with 20 amperes maximum branch circuit over-current protection in accordance with the
National Electric Code, ANSI/NFPA 70”. An AC output disconnect shall be provided by others.
16. CAUTION (For 3000VA Models Only):
with 30 amperes maximum branch circuit over-current protection in accordance with the
National Electric Code, ANSI/NFPA 70”. An AC output disconnect shall be provided by others.
17. CAUTIO
type TW cable, trade size 1 in. conduit, 60°C, copper wire for input an output field wiring. For
3000VA models: Use No. 8 AWG type TW cable, trade size 1 in. conduit, 60°C, copper wire for
input and output field wiring. Use tightening torque of 40Nm to secure wiring to terminal block.
N (For Models with I/P Terminal Block): For 800 - 2000VA models: Use No. 10 AWG
To reduce risk of fire, connect only to a circuit provided
Marathon Power's Track models are ideal for more critical applications where a true sine wave
output while in backup mode is required along with the efficiency of a line-interactive design. Tapchanging AVR (Automatic Voltage Regulation) provides mitigation of sags and swells without the
need to transfer to battery. Battery energy is conserved for more severe disturbances such as
interruptions and outages.
Tight voltage and frequency regulation along with fast transfer ensures the seamless transfer of
uninterrupted power to the load. Included is generic power monitoring & UPS control software.
They feature a unique energy saving “Sleep Mode” that reduces the cost of ownership and
“Cold Start” that allows the UPS to be used as a small emergency power source.
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 require other optional software)
There are dry contacts or solid state signalling via a standard RS-232 port that allows for remote
notification of basic functions such as Power Normal, Backup Mode, & Low Battery states.
* Software is presently available for PC operating systems only.
2. Safety
WARNINGS AND CAUTIONS!
!
Please be aware of, and observe the following:
• To reduce the risk of electric shock, disconnect the UPS from the main AC supply before installing any
interface cables. Reconnect the power cord only after the signaling interconnections have been made.
• The internal energy source (the battery) cannot be de-energized by the user. The output may be
energized when the unit is not connected to the AC supply.
• The correct way to de-energize the UPS properly in an emergency is to move the I/O switch to the
OFF position and disconnect the power cord from the main supply.
• Even when the unit is disconnected, risk of electric shock from parts energized by the battery inside unit
still exists. To avoid this, the battery supply should be disconnected at positive and negative terminals.
• The outlet sockets should be installed near the equipment and easily accessible.
• Do not dispose of batteries in a fire as they may explode. Please contact tech support for proper
disposal instructions.
• Do not open or attempt to dismantle the battery, as electrolyte that is harmful to the skin and eyes
may be released.
• A battery can present a risk of electric shock and high short circuit current. The following precautions
should be taken when working with them:
- Remove watches, rings and other jewelry or metal objects.
- Use tools with insulated handles.
• To reduce risk of fire, replace only with same type and rating of fuse.
• To reduce the risk of fire or electric shock, install the UPS in a temperature and humidity controlled
indoor area free of conductive contaminants.
