PanelView Plus 700 to 1500 and PanelView Plus Compact 1000 Terminals and Display Modules
Application Information
Per the National Electrical Code the circuit parameters of nonincendive field wiring apparatus
for use in hazardous locations shall be coordinated with the associated nonincendive field wiring
apparatus such that their combination remains nonincendive. The PanelView Plus terminals and
the USB peripheral device shall be treated in this manner.
The circuit parameters of the PanelView Plus USB port are given in Table 1. The USB peripheral
device and its associated cabling shall have circuit parameters with the limits given in Table 2 for
them to remain nonincendive when used with the PanelView Plus USB port. If cable capacitance
and inductance are not known the following values from ANSI/ISA-RP 12.06.01-2003 may be
used:
C
cable
= 197 μF/m (60 μF/ft)
L
cable
= 0.7 μF/m (0.20 μH/ft)
Nonincendive field wiring must be wired and separated in accordance with 501.10(B)(3) of the
National Electrical Code (NEC) ANSI/NFPA 70 or other local codes as applicable.
This associated nonincendive field wiring apparatus has not been evaluated for use in
combination with another associated nonincendive field wiring apparatus.
Wiring and Safety Guidelines
Use publication NFPA 70E, Electrical Safety Requirements for Employee Workplaces, IEC
60364 Electrical Installations in Buildings, or other applicable wiring safety requirements for the
country of installation when wiring the devices. In addition to the NFPA guidelines:
• Connect the device and other similar electronic equipment to its own branch circuit.
• Protect the input power by a fuse or circuit breaker rated at no more than 15 A.
