Compliance Declarations 

FCC Compliance Information 

This equipment has been tested and found to comply with the limits for a Class A digital device, 

pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection 

against harmful interference when the equipment is operated in a commercial environment. This 
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in 

accordance with the instruction manual, may cause harmful interference to radio communications. 
Operation of this equipment in a residential area is likely to cause harmful interference in which 

case the user will be required to correct the interference at his own expense. 

 

Industry Canada Compliance Statement 

ICES-003   This Class A digital apparatus meets all requirements of the Canadian Interference-

Causing Equipment Regulations. 

 

Cet appareil numérique de la Classe A Respecte toutes les exigences du Règlement sur 

le matérial brouiller du Canada. 

 

UL Compliance Information 

 

 

This product conforms to the following UL requirements: 

 

UL916: Energy Management Equipment 

 

CAUTION – Risk of Electric Shock – More than one disconnect switch may 
be required to de-energize the equipment before servicing 

 

AVERTISSEMENT – Risque d'électrocution. Plus d'un interrupteur général 
peut être requis pour mettre l'équipement hors tension avant de procéder 

à son entretien 

 

All terminals are acceptable for Class 2 circuit connection only 

 

CAUTION – Input Class 2 Power Supplies are interconnected.  To Reduce 
the Risk of Fire or Electric Shock, Use only Class 2 sources Suitable for 

Interconnection 

 

AVERTISSEMENT – Les alimentations de classe 2 sont interconnectées. 

Pour réduire le risque d'incendie ou de décharge électrique, n'utiliser 
qu'une source d'alimentation de classe 2 adaptée 

 

Use Copper Conductor Only 

 

Select an external power supply that is certified for safety for the correct 

destination country and that has an output rating, which is considered an 
NEC Class 2 or Limited Power Source with the rating not to exceed 30 V 

rms, 42.4 V peak, 100 VA. 

 

Apply minimum 6.0 lb-in torque for tightening field wires into the terminal 

blocks.
