IMPORTANT
1. Wiring connections for the relay modules are
unique; refer to Fig. 2 or the appropriate Specifica-
tions for proper subbase wiring.
2. Wiring must comply with all applicable codes,
ordinances and regulations.
3. Wiring must comply with NEC Class 1 (Line Volt-
age) wiring.
4. Loads connected to the RM7885A must not
exceed those listed on the RM7885A label or the
Specifications; see Table 1.
5. Limits and interlocks must be rated to simultane-
ously carry and break current to the ignition trans-
former, pilot valve, and main fuel valve(s).
6. All external timers must be listed or
component-recognized 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 exception of Infrared Flame Detectors
(C7015).
9. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and
used in accordance 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.
10.This digital apparatus does not exceed the Class B
limits for radio noise for digital apparatus set out
in the Radio Interference Regulations of the Cana-
dian Department of Communications.
Location
Humidity
Install the relay module where the relative humidity never
reaches the saturation point. The relay module is designed
to operate in a maximum 85% relative humidity
continuous, noncondensing, moisture environment.
Condensing moisture can cause a safety shutdown.
Vibration
Do not install the relay module where it can be subjected
to vibration in excess of 0.5G continuous maximum
vibration.
Weather
The relay module is not designed to be weather tight.
When installed outdoors, protect the relay module in an
approved weather-tight enclosure.
