The PanelView Plus terminals are suitable for use in an industrial
environment when installed in accordance with these instructions.
Specifically, this equipment is intended for use in clean, dry
environments (Pollution Degree 2
Over Voltage Category II
(1) Pollution Degree 2 is an environment where, normally only non-conductive pollution occurs except that
occasionally a temporary conductivity caused by condensation shall be expected.
(2) Over Voltage Category II is the load level section of the electrical distribution system. At this level transient
voltages are controlled and do not exceed the impulse voltage capability of the product's insulation.
(3) Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commissions (IEC)
designations.
The terminals must be mounted in a panel or enclosure to protect the
internal circuitry. The terminals meet IP54 and NEMA Type 12/13 and
4X (indoor) ratings only when mounted in a panel or enclosure with
the equivalent rating. When the terminal is not mounted in a panel, it
is not secure or safe for operation. You must comply with NEMA Type
4X (indoor) requirements for environmental specifications.
You must allow adequate clearances around the terminal, inside 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 ºF).
Minimum clearances for ventilation are:
• top and bottom clearance: 51 mm (2 in)
• side clearances: 25 mm (1 in)
Maximum side clearance for insertion of memory card and cable
wiring is 102 mm (4 in).
Besides the tools required for the panel or enclosure cutouts, you will
need the following for installation:
• small slotted screw driver
• torque wrench (N•m/in-lb)

and with circuits not exceeding
(2) (3)
(IEC 60664-1).
