Specifica-		Battery life	Controller power OFF		Approx. 3 years under standard conditions
tions			Controller power ON		Approx. 10 years under standard conditions
	Rated power voltage	90 to 264Vac, 50/60Hz

	Handling Precautions
	When starting up a number of DCP31s simultaneously, ensure ample power is supplied
	or stagger startup times. Otherwise, the controllers may not start normally due to inrush
	current induced-voltage drop. Voltage must stabilize within 2s after power ON.
Power ON operation	Reset time:	15s max. (time until normal operation possible under normal operating
	conditions)
Allowable transient power	20ms max. (under operating conditions)
