SIL3Capable 66-1085-04 RM7800E,G,L,M; RM7840E,G,L,M 7800 SERIES RELAY MODULES RM7800E,G,L,M; RM7840E,G,L,M 7800 SERIES RELAY MODULES WARNING Electrical Shock Hazard. Can cause serious injury or death. Disconnect the power supply before beginning installation. More than one power supply disconnect may be required. IMPORTANT 1. Wiring connections for the relay modules are unique; therefore, refer to Fig. 2, 3, 4, or the correct Specifications for proper subbase wiring, and sequence charts. 2. Wiring must comply with all applicable codes, ordinances and regulations. 3. Wiring must comply with NEC Class 1 (Line Voltage) wiring. 4. Loads connected to the RM7800/RM7840 must not exceed those listed on the RM7800/RM7840 label or the Specifications, see Table 1. 5. Limits and interlocks must be rated to simultaneously carry and break current to the ignition transformer, pilot valve, and main fuel valve(s). 6. All external timers must be listed or component recognized by authorities who have jurisdiction for the specific purpose for which they are used. 7. For on-off gas-fired systems, some authorities who have jurisdiction prohibit the wiring of any limit or operating contacts in series between the flame safeguard control and the main fuel valve(s). 8. Two Flame Detectors can be connected in parallel with the exception of Infrared Flame Detectors (C7015, C7915), Ultraviolet Flame Detectors (C7927, C7961) or Visible Light Detector (C7962). 9. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause interference to radio communications. It has been tested and found to comply with the limits for a Class B computing device of Part 15 of FCC rules which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area may cause interference; in which case, the users at their own expense may be required to take whatever measures are required to correct this interference. 10...
