Precautions
Backup Power Supply for Memory Protection
during Power Failure
The Model H5L Time Switch has 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 or puncture 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
time switch mounted on a board, remove the time switch body to iso-
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.
Water or oil spray.
Dust.
Direct sunlight.
Organic solvents (thinner or benzine), strong acids or bases.
If operating conditions exceed the above values, be sure to connect
a surge absorber. When switching inductive loads, counterelectro-
motive force is generated. When using the H5L as a switch contac-
tor or for similar functions, connect a surge absorber to prevent mal-
functions or damage to the timer.

Perform wiring so that the potential across the output contacts is the
same. This prevents short circuiting of the contacts as shown below.
Correct
The optional cover (Y92A-96A) is recommended for dusty condi-
tions.
Do not take the case off the body.
When using the time switch in conditions subject to static electricity,
(caused by transportation of molding materials and liquid materials
with pipes), isolate the time switch from the source of the static elec-
tricity.
The storage temperature range for the time switch is --25"C to 65"C.
If the time switch is stored at temperatures below --10"C leave if
more than 3 hours at the room temperature and then apply the pow-
er.
WARNING
!
Fire, Explosion, and Severe Burn Hazard
The H5L has a built-in lithium battery. Be sure to dispose of the
old H5L properly, as lithium batteries are likely to explode if in-
cinerated.
