Chapter 8 Installing the PV550 Terminal
The following PV550 terminals have an operating temperature code of
T2 (maximum operating temperature of 300
°
C or 572 °F).
•
keypad terminals (series G or earlier)
•
keypad and touch screen terminals (series G or earlier)
•
touch screen only terminals (series A)
Do not install these terminals in environments where atmospheric
gases have ignition temperatures less than 300 °C (572 °F).
The following PV550 following PV550 terminals have an operating
temperature code of T4 (maximum operating temperature of 135 °C or
275 °F).
•
keypad terminals (series H and later)
•
keypad and touch screen terminals (series H and later)
•
touch screen only terminals (series B and later)
Do not install these terminals in environments where atmospheric
gases have ignition temperatures less than 135 °C (275 °F).
Enclosures Mount the PV550 terminal in a panel or enclosure to protect the
internal circuitry. The terminal meets NEMA Type 12/13 and 4X
(indoor use) ratings only when mounted in a panel or enclosure with
the equivalent rating.
Allow enough space within the enclosure for adequate ventilation.
Consider heat produced by other devices in the enclosure. The
ambient temperature around the terminals must be between 0… 55 °C
(32…131 °F).
Make provisions to access the back panel of the terminal for wiring,
maintenance, installing a memory card and troubleshooting.
