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

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:
