The MessageView 421 terminal must be mounted in a panel or
enclosure to protect the internal circuitry. The terminal meets NEMA
Type 12 / 13 and Type 4X (indoor use) only when mounted in a
panel or enclosure with the equivalent rating.
The MessageView 421 terminal must be mounted in an environment
that provides IEC-1131-2 Pollution degree 2 protection.
Allow enough space within an enclosure for adequate ventilation.
For some applications, you may have to consider heat produced by
other devices within a panel. The ambient temperature around the
terminal must be between 32
_ and 131_F (0_ and 55_ C).
Make sure that provisions are made for accessing the back and
bottom of the terminal for wiring, routine maintenance, and
troubleshooting.
Other than the tools required to make the panel cutout, the tools
required for installation are:
•
small slotted screwdriver
•
torque wrench (in. / lbs) with 7mm (M4) deep well socket.
The terminal is tightened against the panel with self-locking nuts.
•
six nuts (421D & 421N terminals)
•
eight nuts (421F terminals)
Use a torque of 15 inch-pounds (1.7 Nm). to tighten the terminal
against the panel with the self-locking nuts.
