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
connector, even if the UPS appears to be off.
▪ 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.
▪ Always disconnect the AC input cable from the source of AC power before disconnecting it
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 AC OUTPUT cable and connector:
▪ Do not assume that a hazardous voltage is not present at the terminals of the AC output
connector, even if the UPS appears to be off.
▪ Do not make contact with the terminals of the AC output connector.
▪ Connect the AC output cable to the UPS before the UPS is turned on.
▪ If connection of the load to the AC output cable has exposed conductors, make this connection
before connecting the AC output cable to the UPS.
▪ Connections between the AC output cable and the load should not be accessible.
• 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 AC outputs with
reinforced safety insulation.
▪ 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 off.
