<Cautions>
• The rear face of the FP unit is not a part of an enclosure. This unit must be used as a built-in component of an end-use
product that forms a UL/c-UL-compliant enclosure.
• For indoor use only.
• This unit should be installed in the front face of a metal panel.
• If this unit is installed so as to cool itself naturally, be sure to install it in a vertical panel.
Also, be sure that the FP unit is mounted at least 100 mm away from any adjacent structures or equipment. If these
requirements are not met, the heat generated by the FP unit’s internal components may cause the unit to fail to meet
UL/c-UL standard requirements.
• For use on a flat surface of a Type 1 Enclosure (FP3500-T41-24V/FP3600-T41-24V only).
• For use on a flat surface of a Type 4X (Indoor Use Only) and/or Type 12 Enclosure (FP-3710T/3900T Series only).
• Type 4X (Indoor Use Only) and/or 12 Enclosure, when the hatch for Front USB Port is secured by screw.
Type 1 Enclosure, when the hatch for Front USB Port is open.(FP3710-T41-U, FP3710-T42-U, FP3900-T41-U only)
• Receivable signals are only from isolated secondary source.
• All interface ports (except for Front USB Connector (Type A) ) are not intended to be directly connected to a signal
source greater than 30 volts and available current greater than 5mA.
<Compliance and Handling Cautions in Hazardous Locations>
• Suitable for use in Class I, Division 2, Groups A, B, C, and D Hazardous Locations only.
• WARNING: Explosion hazard - substitution of components may impair suitability for Class I, Division 2.
• WARNING: Explosion hazard - do not disconnect equipment while the circuit is live or unless the area is known to be
