IMPoRtAnt
1 Wiring connections for the relay modules are unique; refer
to page 8 (4.2.3 Fig. 2. Wiring subbase and operating
sequence chart for RM/EC7890) or the appropriate Specifica-
tions for individual subbase wiring.
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 RM/EC7890 must not exceed those
listed on the RM/EC7890 label or the Specifications; see page
5 (3.5.3 Table 3. Terminal Ratings.), page 5 (3.5.4 Table
4. Combinations for Terminals 8, 9, and 10.), and page 7
(4.2.1 Table 5. Static Checkout.).
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 componentrecognized by
authorities who have proper jurisdiction.
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
following exceptions:
• C7927 Ultraviolet Detector
• C7915 Infrared Detector
9 This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accord-
ance with the instructions, can cause interference with 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
can cause interference, in which case, the users, at their own
expense, may be required to take whatever measures are
required to correct this interference.
