Precautions
Backup Power Supply for Memory Protection
during Power Failure
TheModelH5LTimeSwitchhas a built-in battery.This backup pow-
er supply allows continuous operation of the internal timer circuit
during a power failure. If the duration of a power failure or service
interruption is within the life-time of the backup battery, no time ad-
justment is required for the timer. Note that during a power failure,
the output contacts are in the OFF state and the display is dark.
The backup battery has a life-time of 10 years assuming normal
usage.
Please do not burn orpuncture the lithium battery included with this
product, since it poses a health hazard.
Others
The load current of the control output should be within the ratings
specified in the connection diagram. If these ratings are exceeded,
the contact service life will be reduced significantly.
When doing impulse voltage or insulation resistance tests with the
timeswitchmountedonaboard,removethetimeswitchbodytoiso-
late the time switch circuit. This will prevent degradation or damage
to the internal circuitry of the time switch.
When using the timer switch under noisy condition, isolate the time
switch from any noise sources or high power lines.
Avoid the following conditions:
Corrosive gases.
Constant vibrations or large shocks.
Wateroroilspray.
Dust.
Direct sunlight.
Organic solvents (thinner or benzine), strong acids or bases.
If operatingconditions exceed theabove values, besureto connect
a surge absorber. When switching inductive loads, counterelectro-
motive force is generated. When using the H5L as a switch contac-
tor or forsimilarfunctions, connect asurgeabsorber to preventmal-
functions or damage to the timer.
Perform wiringsothat thepotential across theoutput contacts is the
same.Thisprevents shortcircuitingofthecontactsasshownbelow.
Correct Incorrect
The optional cover (Y92A-96A) is recommended for dusty condi-
tions.
Do not take the case off the body.
Whenusing thetimeswitch in conditions subjectto static electricity,
(caused by transportation of molding materials and liquid materials
withpipes), isolate the time switchfrom thesource ofthe static elec-
tricity.

WARNING
Fire, Explosion, and Severe Burn Hazard
TheH5L has abuilt-inlithiumbattery.Be sureto dispose ofthe
old H5L properly, as lithium batteries arelikely to explode if in-
cinerated.
