1 SNOW MELTING AND DE-ICING POWER DISTRIBUTION AND CONTROL PANEL For three-phase heating cables Mounting brackets Nameplate HTC energized light Power on light Heater cycle timed control Heater (3R only) G R Heater thermostat (3R only) Door lock handle G Alarm acknowledge C.B. tripped alarm PRODUCT OVERVIEW The Raychem SMPG3 is a three-phase power distribution panel for three-phase heating cables that includes ground-fault protection, monitoring and control for snow melting or roof and gutter de-icing systems. The ETI EUR-5A snow melting and gutter de-icing controller is included with the SMPG. When used with one or more compatible sensors, the EUR-5A automatically controls surface snow melting and roof and gutter de-icing heating cables for minimum energy costs. Applications include pavement, sidewalk, loading dock, roof, gutter, and down spout snow/ice melting in commercial and industrial environments. The adjustable hold-on timer continues heater operation for up to 10 hours after snow stops to ensure complete melting.

It also permits safe testing at outdoor temperatures too high for continuous heater operation. The temperature sensor is included. The EUR-5A provides a complete interface for use in environments supervised by an energy management computer (EMC). This feature can also be used for general purpose remote control and annunciation. All sensor and communications wiring is NEC Class 2. This simplifies installation while enhancing fire and shock safety. Multiple sensors provide superior performance by better matching the controller to site performance requirements. The EUR- 5A can interface up to six sensors. For single-phase heating cable configurations, refer to the SMPG1 data sheet (H57680).

To comply with NEC Article (a), all circuit breakers are equipped with the means for lockout in the Off position. UL STD. 508A CAN/CSA C22.2 NO. 14 GROUND-FAULT PROTECTION To minimize the danger of fire from sustained electrical arcing if the heating cable is damaged or improperly installed, and to comply with the requirements of Thermal Management, agency certifications, and national electrical codes, ground-fault equipment protection must be used on each heating cable branch circuit. Arcing may not be stopped by conventional circuit protection. Many Raychem control and monitoring systems meet the ground-fault protection requirement.

3 CATALOG NUMBER SMPG3 comes in a variety of configurations. The following chart outlines the elements that constitute a configuration and the corresponding catalog number. If standard configurations do not meet your needs, custom SMPG panels are available and processed under the catalog number SMPG-GENERAL, part number P Please contact your Thermal Management representative for a custom SMPG panel quotation. Non-standard configurations will carry ETL Certification, not a UL Listing.
