DESCRIPTION
Output Frequency Automatic
(50 ± 3 Hz or
60 ± 3 Hz)
Automatic,
50 ± 3 Hz,
50 ± 0.1 Hz,
60 ± 3 Hz,
60 ± 0.1 Hz
The user is able to set the allowable
uninterruptible power supply output
frequency. Whenever possible, the
output frequency tracks the input fre-
quency.
Number of Battery
Packs
1 Number of Con-
nected Battery Packs
(four battery modules
per pack)
The user can define the number of con-
nected battery packs for proper runtime
prediction.
Emergency Power Off (EPO) Option
The output power can be disabled in an emergency by closing a switch connected to the EPO.
Note: Adhere to national and local electrical codes when wiring.
The switch should be connected in a normally open switch contact. External voltage is not required; the switch is powered by a
12 V internal power supply. A closed switch draws 2 mA of current.
The EPO switch is internally powered by the uninterruptible power supply for use with non-powered switch circuit breakers.
Note: The EPO circuit is considered a Class 2 circuit, (UL, CSA standards) and an SELV circuit (IEC standard).
Both Class 2 and SELV circuits must be isolated from all primary circuitry. Do not connect any circuit to the EPO terminal
block unless it can be confirmed that the circuit is Class 2 or SELV.
If the circuit standard cannot be confirmed, use a contact closure switch.
Use one of the following cable types to connect the uninterruptible power supply to the EPO switch:
• CL2: Class 2 cable for general use
• CL2P: Plenum cable for use in ducts, plenums, and other spaces used for environmental air
• CL2R: Riser cable for use in a vertical run in a floor-to-floor shaft
• CLEX: Limited use cable for use in dwellings and for use in raceways
• For installation in Canada: Use only CSA certified, type ELC (extra-low voltage control cable)
• For installation in other countries: Use a standard low-voltage cable according to local regulations
