H2F-D/-DF Series: Synchronous Motor
Models
Before mounting the Time Switch, set the
frequency switch to the frequency for the
region where the Time Switch will be
used.

Motor Models
• Remove the battery
cover on the back of the
Time Switch. Be sure to
insert the battery
before supplying power.
Operating the Time
Switch without the
battery mounted will
increase the time error.
Always mount the
battery.
• Pay careful attention to the polarity
when inserting the battery. Insert
the battery following the polarity
marked in the battery box of the
Time Switch. Before using the Time
Switch, be sure to close the battery
cover after the battery is inserted.
• The enclosed battery is fully
charged. In the rare event that battery performance decreases due
to natural discharging, the 180-hour power interruption backup
function will back up operation if power has been continuously
supplied for 72 hours after installing the battery in the Time Switch.
If the battery is completely discharged, the Time Switch may not
operate when the battery is installed. If the Time Switch does not
operate, supply power for at least 3 min, and then set the time.
• Turning the power supply ON and OFF will extremely shorten the
service life of the battery. Use the Time Switch with the power
supplied continuously.
• The service life of the battery is approximately three years (at room
temperature). If the battery has been used for three years or more,
replace it as soon as possible. Using the battery close to the end of
its service life will increase the time error.
• The battery may leak or cause corrosion due to excessive
discharge if the H2F is left unused for an extended period with the
battery mounted. Be sure to remove the battery before storing the
H2F.
• Turn OFF the power supply before replacing the battery.
• Use only the specified battery (Y92S-42). The battery may leak or
burst if any other battery is used, possibly resulting in equipment
damage or injury.
Other Precautions
• Always use a thermo-switch on the load circuit when a heater is
used.
• Operate the Time Switch within the specified rating ranges for
vibration and shock.
• The H2F is not waterproof or oil resistant. Do not use the H2F in
locations subject to water splashing or oil contact.

Notice
There is no alternative product for the Y92S-22 Nickle-Cadmium
Battery. Replace the entire H2F Time Switch.
CAUTION
As the result of design changes in March 2006, the backup battery
for the H2F Motor Time Switches was changed from the Y92S-22
Nickel-Cadmium Battery to the Y92S-42 Nickel-Hydrogen Battery.
The Y92S-22 Nickel-Cadmium Battery and the Y92S-42 Nickel-
Hydrogen Battery are not compatible as replacement batteries. If you
attempt to use the Y92S-42 Nickel-Hydrogen Battery with H2F Time
Switches from before the design change (i.e., Switches designed for
a Y92S-22 Nickel-Cadmium Battery), an insufficient charge may
prevent operation.
Or, if you use the Y92S-22 Nickel-Cadmium Battery in an H2F Time
Switch designed for the Nickel-Hydrogen Battery, an overcharge may
cause the battery to leak.
Check the internal battery specifications on the label on the battery
cover on the H2F and on the external markings on the battery.
