Using DC Power
Quantum Spark 1570R Appliance R80.20.XX Getting Started Guide | 17
This equipment is intended for power supplied by DC mains.
n
The product supports 10.2VDC~72VDC, but with no power input tolerance.
Make sure the product is connected with a power supply of output voltage lower than 72VDC. A UPS,
battery or power regulator is recommended.
n
If the power supply cannot provide stable voltage, we recommend to select lower voltage like 48VDC
to prevent damage due to over voltage.
Field Wiring for DC Mains
Only trained service personnel are authorized to install and remove the 12VDC-60VDC Mains or the power
adapter AC2DC, and make the connections to and disconnections from the 12VDC-60VDC Mains.
The customer is responsible for ensuring that only trained service personnel install or remove the 12VDC-
60VDC power cable.
Safety Statement
Caution
To reduce the risk of electric shock or energy hazards:
n
It is the customer's responsibility to supply the necessary power cable.
n
Use a circuit breaker that is rated at 20 amps.
n
Use one of these wires with a minimal temperature rating of 90°C:
l
1.5 mm
2
(14 AWG) single copper wire
l
1.5 mm
2
(14 AWG) multi-core copper
n
Strip the wire, and leave the bare lead approximately 10mm for terminals connection.
n
Torque the wiring-terminal screws to 0.60 Newton/meter (5 Pound/inch).
n
Wire strip length is 4-4 mm.
n
For supply connections, use wires with a minimal temperature rating of 90°C.
n
If the power source requires ring terminals, you must use a crimping tool to install the ring terminals to
the power cord wires.
The ring terminals must be UL approved and must accommodate the wire that is described above.
This equipment is designed to permit the connection the earthed conductor of the DC supply circuit to the
earthed conductor at the equipment. If this connection is made, all of the following conditions must be met:
n
This equipment shall be connected directly to the DC supply system earthed electrode conductor or
to a bonding jumper from an earthing terminal bar or bus, to which the DC supply system earthed
electrode conductor is connected.
n
This equipment shall be located in the same immediate area (such as, adjacent cabinets) as any
other equipment that has a connection between the earthed conductor of the same DC supply circuit
and the earthed conductor, and also the point of earthed of the DC system. The DC system shall not
be earthed elsewhere.
n
The DC supply source shall be located within the same premises as this equipment.
