Please note the following to comply with EN60730 for
remote mounting of the KDM and/or remote reset module.
It is necessary to provide electrical separation using
insulation at least equivalent to double or reinforced
insulation. This can be accomplished by either:
1. Optically isolating the communication and/or
remote reset lines from the control cabinet or
2. Providing physical separation from the
communication and/or remote reset lines using
electrical conduit and a 204718A Remote Display
Cover Assembly or other suitable enclosure that
meets NEMA4 class of protection.

Continuous Operation Note
Non-check amplifiers cannot be used in continuous
operation (per EN298). For continuous operation only
ampli-check or shutter/self-check flame amplifiers are
used.
Non-check amplifiers trigger the device to automatically
recycle after 24 hours when in a continuous run mode.
IMPORTANT
1. Wiring connections for the relay modules are unique;
refer to Fig. 4 and 5 or the appropriate Specifications
for individual subbase wiring.
2. Wiring must comply with all applicable codes, ordi-
nances and regulations.
3. Wiring must comply with NEC Class 1
(Line Voltage) wiring.
4. Loads connected to the EC/RM7830A and
EC/RM7850A must not exceed those listed on the
relay module 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).
