Notes
•
In the case of voltages above 30 VAC/DC and if inductive
components are to be connected to relays switching
more often than once every 2 minutes, these com-
ponents must be prevented from causing harmful
interference to radio or television reception (conformance
with EN 55014).
•
Max. voltage for UL 864-compliant applications is 24 V.

manual overrides: one for each relay output. These sliding
switches can manually be set to either "auto" or "0" or "1".
