Agency Certification

(when product or packaging is marked)

The commutating dv/dt of the output voltage (OUTPUT to L2) should not exceed 0.2V/

s for loads under 50mA. The

commutating dv/dt rating of the module for loads 50-500mA (OUTPUT TO L2) is 4V/

s maximum. If the commutating

dv/dt rating of the TRIAC is exceeded, the TRIAC could latch on. If the commutating dv/dt rating is exceeded in the

10-50mA range, a resistor may be added across the output and L2. The purpose of this resistor is to increase the total

output current to 50mA (I=V/R). At 50mA and above, the module has a higher commutating dv/dt rating. When adding a

resistor for mthe output to L2, be sure it is rated for the power that it will dissipate (P=(V**2)/R). If the commutating dv/dt

rating is exceeded in the 50-500mA range, the L1 AC waveform could be at fault. Be sure the waveform is a good

sinusoid, void if any anomalies such as distorted or flattened sections.

Maximum wire size will require extended housing - 1756-TBE.

Use this conductor category information for planning conductor routing as described in

the system level installation manual.

FM approved–Class I, Division 2, Group A, B, C, D or nonhazardous locations.

CSA certifies products for general use as well as for use in hazardous locations. Actual CSA certification is

indicated by the product label as shown below, and not by statements in any user documentation.

Example of the CSA certification product label:

To comply with CSA certification for use in hazardous locations, the following information becomes a part of

the product literature for this CSA-certified industrial constrol product::

•

This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D, or non-hazardous locations only.

•

The products having the appropriate CSA markings (that is, Class I, Division 2, Groups A, B, C, D) are

certified for use in other equipment where the suitability of combination (that is, application or use) is

determined by the CSA or the local inspection office having jurisdiction.

IMPORTANT

Due to the modular nature of a programmable control system, the product with the

highest temperature rating determines the overall temperature code rating of a

programmable control system in a Class I, Division 2 location. The temperature code

rating is marked on the product label as shown.

The following warnings apply to products having CSA certification for use in hazardous locations.

ATTENTION

Explosion hazard!

•

Substitution of components may impair suitability for Class I, Division 2.

•

Do not replace components unless power has been switched off or the area is

known to be non-hazardous.

•

Do not disconnect equipment unless power has been switched off or the area

is known to be non-hazardous.

•

Do not disconnect connectors unless power has been switched off or the area

is known to be non-hazardous. Secure any user-supplied connectors that mate

to external circuits on this equipment by using screws, sliding latches,

threaded connectors, or other means such that any connection can withstand

a 15 Newton (3.4 lb) separating force applied for a minimum of one minute.

•

If the Product contains batteries, they must only be changed in an area known

to be non-hazardous.

La CSA certifie des produits pour une utilisation générale aussi bien que pour une utilisation en

environnements dangereux. La certification CSA en vigueur est indiquée par l'étiquette produit et non par des

indications dans la documentation utilisateur.

Exemple d'étiquette de certification d'un produit par la CSA:

Pour satisfaire à la certification CSA en environnements dangereux, les informations suivantes font partie

intégrante de la documentation des produits de commande industrielle certifiés.

•

Cet équipement ne convient qu’à une utilisation en environnements de Classe 1, Division 2,

Groupes A, B, C, D ou non dangereux.

•

Les produits portant le marquage CSA approprié (c'est-à-dire Classe 1, Division 2, Groupes A, B, C, D) sont

certifiés pour une utilisation avec d'autres équipements, les combinaisons d’applications et d’utilisations

étant déterminées par la CSA ou le bureau local d'inspection qualifié.

IMPORTANT

De par la nature modulaire des systèmes de commande programmables, le produit ayant

le code de température le plus élevé détermine le code de température global du

système dans un environnement de Classe 1, Division 2. Le code de température est

indiqué sur l'étiquette produit.
