Install the PanelView 5500 Terminal
Required Circuit Port Parameters for USB Peripheral Devices
This product contains USB host ports that comply with hazardous location environments. Field-wiring compliance
requirements are provided in compliance with the National Electrical Code, Article 500.
Figure 2 - PanelView 5500 Control Drawing
PanelView 5500 terminals provide two, separately powered USB host ports.
defines the circuit parameters of these
USB host ports.
Application Information
Per the National Electrical Code, the circuit parameters of associated field-wiring apparatus for use in hazardous locations
shall be coordinated with the host product such that their combination remains nonincendive. PanelView 5500 terminals
and the USB peripheral devices shall be treated in this manner.
The USB peripheral devices and their associated cabling shall have circuit parameters with the limits given in
for
them to remain nonincendive when used with the PanelView 5500 USB host ports.
If cable capacitance and inductance are not known, use the following values from ANSI/ISA-RP 12.06.01-2003:
C
cable
= 197 pF/m (60 pF/ft)
L
cable
= 0.7 μH/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.
