Chapter 2 Installation
The terminals have a temperature code of T4 when operating in a 55
°C (131 °F) maximum ambient temperature. Do not install the
terminals in environments where atmospheric gases have ignition
temperatures less than 135 °C (275 °F).
USB Ports
The terminals contain universal serial bus (USB) ports that comply
with hazardous location environments. This section details the
field-wiring compliance requirements and is provided in accordance
with the National Electrical Code, article 500.
