a) End-of-Line devices (P/N REL-47K) are not required; however, the releasing device circuit
is not supervised against shorts.
b) Limited energy cable cannot be used for wiring of a releasing device circuit.
c) Maintain a 0.25 inch (6.35 mm) spacing between the releasing circuit device wiring and any
power-limited circuit wiring.
d) In non-power-limited applications, program the releasing circuit for Type Code
