Section I Warnings
Hazardous Voltages
The INPUT AND OUTPUT POWER connectors and cables of the SynQor UPS may have
voltages that are unsafe. INJURY OR DEATH ON CONTACT may result. Appropriate safety
precautions should be taken. All connections should be made in accordance with LOCAL
ELECTRICAL CODES.
• The UPS CHASSIS should be connected to earth or system ground with Ground Stud on the
rear panel, see mechanical diagrams.
• For the AC INPUT cable and connector:
Do not assume that a hazardous voltage is not present at the terminals of the AC input
Do not make contact with the terminals of the AC input connector.
Always connect the cable to the UPS before it is connected to the source of AC power.
from the UPS.
If the AC input cable is connected to the source of AC power and not connected to the UPS,
do not contact the exposed terminals of the AC input cable.
Do not assume that the source of AC power is not present.
Connections between the AC input cable and the source of AC power should not be
accessible.
• For the DC3 OUTPUT cable and connector:
Do not assume that a hazardous voltage is not present at the terminals of the DC3 OUTPUT
Do not make contact with the terminals of the DC3 OUTPUT connector.
Connect the DC3 OUTPUT cable to the UPS before the UPS is turned on.
• For the DC INPUT cable and connector (if present):
The rated DC input voltage of the UPS is below the level considered hazardous.
The DC input terminals of the UPS are isolated from the AC input and DC3 OUTPUTs with
However, never assume the terminals of the DC input connector or the wires of the DC input
cable are safe to contact, even if the UPS or DC input source appears to be o.

Hazardous Energies
The INPUT AND OUTPUT POWER connectors and cables of the SynQor UPS may be the source
of high levels of energy. Do not inappropriately make electrical contact between any terminal of
a connector and another, or between any wire of a cable and another, or between any terminal
