			Section
Safety	□	Does the vehicle system have a fail-safe in case of a relay failure?	ｐ1/1-1、ｐ1/2-4
	□	Has it been confirmed by testing under actual load, actual circuit, and	ｐ2/4-1
		actual condition?
	□	Have load type, load current characteristic, and current value been	ｐ2/4-2～4-9
		checked?
	□	Isn't the applied contact current too small ? (Small current is likely to	ｐ2/4-10
		decrease the contact reliability.)
	□	Has connecting load polarity been checked?	ｐ2/4-11
	□	Is the load likely to cause instant voltage drop?	ｐ2/4-12
	□	Isn't the applied contact voltage too high? (High voltage decreases	ｐ3/4-13
		electrical life.)
	□	Isn't applied coil voltage too high? (High voltage affects electrical life.)	ｐ3/4-14
	□	Isn't short pulse applied to coil?	ｐ3/4-15
Load/	□	Isn't the switching frequency too high even including at abnormality?	ｐ3/4-16
Electrical life	□	Doesn't switching continue for a long time?	ｐ3/4-17
	□	Does it switch under high temperature?	ｐ3/4-18
	□	Have precautions been checked for using of coil surge absorption	ｐ3/4-19
		circuit?
	□	Have you checked there is no sneak current or voltage to the relay coil?	ｐ3/4-20
	□	Is there stray capacitance between lead wires?	ｐ3/4-21
	□	Have precautions been checked for using of contact protective circuit?	ｐ4/4-22
	□	Is there a risk of dead short in the power supply?	ｐ5/4-23
	□	Is there a risk of short circuit in the power supply at load rejection?	ｐ5/4-23
	□	Is there a risk of insulation and breakdown voltage between contacts in	ｐ5/4-24
		each pole when high voltage is applied to a twin relay?
	□	Has hot start been considered?	ｐ5/5-1
	□	Is the ambient temperature within the range of use? Also, is the ambient	ｐ5/5-2
		temperature characteristics considered?
Coil operation	□	Is the applied voltage below the maximum continuous applied voltage?	ｐ5/5-3
voltage	□	Is there a risk of using PWM control? (PWM control requires careful	ｐ5/5-3
		attention.)
	□	Doesn't coil of twin relay operate at the same time?	ｐ6/5-4
	□	Hasn't the current continuously applied to coil over a long period?	ｐ6/5-5
	□	In case of relay operation by electric circuit, is the circuit designed in	ｐ6/6-1、ｐ8/6-2
Coil operation		consideration of mal-function?
	□	Doesn't the surge voltage of relay cause mal-function or destruction of	ｐ6/6-1、ｐ8/6-2
circuit		transistor circuit?
	□	When relay is applied to an electric circuit, has voltage drop caused by	ｐ6/6-1、ｐ8/6-2
		other electric components on the circuit been considered?
