Chapter 7 Installing the PV300 Terminal

The PV300 terminals have an operating temperature code of T4

(maximum operating temperature of 135 °C or 275 °F). Do not install

these terminals in environments where atmospheric gases have

ignition temperatures less than 135 °C (275 °F).

Enclosures

Mount the PV300 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.

Required Tools

Other than the tools required to make the PV300 panel cutout, the

tools required for installation are:

• 7 mm (M4) deep well socket wrench or nut driver

• small slotted screwdriver

• torque wrench (lb-in)
