Before You Begin
ATTENTION: Before installing, configuring, operating, or maintaining this product, read this document and the documents listed in the additional resources
section for installing, configuring, or operating equipment. Users should familiarize themselves with installation and wiring instructions in addition to
requirements of all applicable codes, laws, and standards.
Installation, adjustments, putting into service, use, assembly, disassembly, and maintenance shall be carried out by suitably trained personnel in accordance with
applicable code of practice. In case of malfunction or damage, no attempts at repair should be made. The module should be returned to the manufacturer for
repair. Do not dismantle the module.
This equipment is certified for use only within the surrounding air temperature range of 0...60 °C (32...140 °F) [PA75R, PB75R, PSCA2] -25...+70 °C
(-13...+158 °F) [PAXTR, PBXTR, PSCA2XT]. The equipment must not be used outside of this range.
Annunciator cable length should be less than 10 m (32.8 ft).
Use only a soft dry anti-static cloth to wipe down equipment. Do not use any cleaning agents.
Environment and Enclosure
ATTENTION: This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in
IEC 60664-1), at altitudes up to 2000 m (6562 ft) without derating.
This equipment is not intended for use in residential environments and may not provide adequate protection to radio communication services in such
environments.
This equipment is supplied as open-type equipment for indoor use. It must be mounted within an enclosure that is suitably designed for those specific
environmental conditions that will be present and appropriately designed to prevent personal injury resulting from accessibility to live parts. The enclosure must
have suitable flame-retardant properties to prevent or minimize the spread of flame, complying with a flame spread rating of 5VA or be approved for the
application if nonmetallic. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may contain
additional information regarding specific enclosure type ratings that are required to comply with certain product safety certifications.
In addition to this publication, see the following:
• Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1, for additional installation requirements.
• NEMA Standard 250 and EN/IEC 60529, as applicable, for explanations of the degrees of protection provided by enclosures.
North American Hazardous Location Approval
The following information applies when operating this equipment in hazardous
locations.
Products marked "CL I, DIV 2, GP A, B, C, D" are suitable for use in Class I Division 2 Groups A, B, C,
D, Hazardous Locations and nonhazardous locations only. Each product is supplied with
markings on the rating nameplate indicating the hazardous location temperature code. When
combining products within a system, the most adverse temperature code (lowest "T" number)
may be used to help determine the overall temperature code of the system. Combinations of
equipment in your system are subject to investigation by the local Authority Having Jurisdiction
at the time of installation.
WARNING: Explosion Hazard
• Do not disconnect equipment unless power has been removed or the
area is known to be nonhazardous.
• Do not disconnect connections to this equipment unless power has
been removed or the area is known to be nonhazardous. Secure any
external connections that mate to this equipment by using screws,
sliding latches, threaded connectors, or other means provided with this
product.
• Substitution of components may impair suitability for Class I, Division 2.
• If this product contains batteries, they must only be changed in an area
known to be nonhazardous.
Informations sur l'utilisation de cet équipement en environnements dangereux.
Les produits marqués "CL I, DIV 2, GP A, B, C, D" ne conviennent qu'à une utilisation en
environnements de Classe I Division 2 Groupes A, B, C, D dangereux et non dangereux. Chaque
produit est livré avec des marquages sur sa plaque d'identification qui indiquent le code de
température pour les environnements dangereux. Lorsque plusieurs produits sont combinés dans un
système, le code de température le plus défavorable (code de température le plus faible) peut être
utilisé pour déterminer le code de température global du système. Les combinaisons d'équipements
dans le système sont sujettes à inspection par les autorités locales qualifiées au moment de
l'installation.
