Chapter 12: Safety, Power, and Environmental Requirements
707042-002 12-3
For units operating at 200-240V
The power cable required for domestic units is a UL listed, CSA certified, 18/3 AWG,
type SVT or SJT cable (9-foot maximum):
• Terminated on one end by a 250V, 15A grounding type attachment connector
• Terminated at the other end by a 250V, 15A tandem blade, grounding type
attachment plug.
For international units
The power cable required is an 18/3 AWG, type SJT cable (9-foot maximum):
• Terminated on one end by a 250V, 15A grounding type attachment plug body
• Terminated at the other end by a 250V, 15A grounding type cord connector.
The cord set is marked HAR to signify appropriate safety approvals. The socket outlet
must be nearby and easily accessible, per IEC 950 Sec. 1.7.2.
Power outlet requirements
The installation site must provide a properly wired and grounded power outlet. Circuits
connected to air conditioners and devices that generate significant transient electrical
noise should be avoided.
Electrical interference and atmospheric considerations
Electrostatic discharge in the vicinity of the unit should be minimized by avoiding high
resistance floor material and carpeting that does not have anti-static properties, by avoiding
the use of plastic seats and covers, and by avoiding low humidity levels. The unit should
be located away from areas that generate electromagnetic interference (for example,
transformers, power distribution panels, welding equipment, motors, and transmitters).
Do not put the unit next to fluorescent lights. The 1783 NCT should not be installed
where the atmosphere contains corrosive elements that can damage the unit.
Do not run the power cable or signal cables in areas that produce electromagnetic
interference (for example, near transformers, switching equipment, welding equipment,
power distribution panels, and under carpets where vacuum cleaning is done). Also, do
not roll heavy equipment over the cable.
