The time setting ring locks the time setting knob to
store the set time to facilitate its resetting. A maximum
of two time setting rings are connectable per timer.
The protective cover shields the front panel, particularly the time setting section, from dust, dirt, and water,
as well as prevents the set value from being altered
due to accidental contact with the time setting knob.

Safety Precautions
■ Precautions for Correct Use
!CAUTION
This may occasionally cause electric shock, fire, or malfunction.
Never disassemble, repair, or modify the H2C.
How to Change the Time Range
This may occasionally cause electric shock, fire, or malfunction.
Do not allow metal fragments or lead wire scraps to fall inside the
H2C.
Change the time range by turning the knob clockwise using a flatblade screwdriver or an Allen wrench. There are five possible
settings. The selected time is displayed in the time range display
window above the knob.
■ Precautions for Safe Use
Observe the following items to ensure the safe use of this product.
Time range
display window
Environmental Precautions
• Store the H2C within the specified ratings. If the H2C has been
stored at temperatures –10°C or lower, let it stand for 3 hours or
longer at room temperature before turning ON the power supply.
• Use the H2C within the specified ratings for operating temperature
and humidity.
• Do not operate the H2C in locations subject to sudden or extreme
changes in temperature, or locations where high humidity may
result in condensation.
• Do not use the H2C in locations subject to vibrations or shock.
Extended use in such locations may result in damage due to stress.
• Do not use the H2C in locations subject to excessive dust,
corrosive gas, or direct sunlight.
• Install the H2C well away from any sources of static electricity, such
as pipes transporting molding materials, powders, or liquids.
• The H2C is not waterproof or oil resistant.
Do not use it in locations subject to water or oil.
• The life expectancy of internal components may be reduced if the
H2C is mounted side-by-side.
• Do not use organic solvents (such as paint thinner or benzine),
strong alkaline, or strong acids because they will damage the
external finish.
Usage Precautions
• Install a switch or circuit breaker that allows the operator to
immediately turn OFF the power, and label it to clearly indicate its
function.
• Be sure to wire the terminals correctly.
• Do not install input lines in the same duct or conduit as power
supply or other high-voltage lines. Doing so may result in
malfunction due to noise. Separate the input lines from highvoltage lines.
• Internal elements may be destroyed if a voltage outside the rated
voltage is applied.
• Maintain voltage fluctuations in the power supply within the
specified range.
• Use a switch, relay, or other contact so that the rated power supply
voltage will be reached within 0.1 s. If the power supply voltage is
not reached quickly enough, the H2C may malfunction or outputs
may be unstable.
• Leaving the H2C with outputs ON at a high temperature for a long
time may hasten the degradation of internal parts (such as
electrolytic capacitors). Therefore, use the H2C in combination with
relays and avoid leaving the H2C for more than 1 month with an
output turned ON.

How to Mount the Timer on Mounting

Pull out portion C with a round-blade screwdriver and remove the
timer from the mounting track.

Auxiliary relay
(e.g., MY Relay)
Use the voltage applied to the clutch for resetting with the H2C-@R.
Do not allow power to be continuously applied to the motor and
clutch for extended periods of time.
Others
Do not turn the operation time setting knob beyond the range of the
scale. To achieve higher accuracy in setting, measure the operation
time while turning the operation time setting knob.
The deviation and setting error for the operation time shows the
percent of FS. The absolute value of the deviation and setting error
will not change even if the set time is changed. The time
specifications should therefore be selected to use the operation time
as close to FS as possible.
At high temperatures, the operation voltage will be 90% or less if
voltage is applied continuously after timeout. Be sure to keep the
voltage within the allowable voltage fluctuation range.
Precautions for EN61812-1
The H2C (except for H2C-F@) as a built-in timer conforms to
EN61812-1, provided that the following conditions are satisfied.
Handling
Before dismounting the H2C from the Socket, make sure that no
voltage is imposed on any terminal of the H2C.
Applicable Sockets: P2CF-@@, P2CF-@@-E, PF085A, PL@@.
Wiring
Basic insulation is ensured between the motor circuit, clutch circuit,
and control output circuit. (However, the H2C-8 motor circuit and
clutch circuit use the same input.) Basic insulation is also ensured
between the output circuits of models with instantaneous output.
Basic insulation: Overvoltage category III, pollution degree 1 (See
note.)
Operating parts: Reinforced insulation (double insulation)
(with a clearance of 5.5 mm and a creepage distance of 5.5 mm at
240 VAC)
Output parts: Basic insulation
(with a clearance of 3.0 mm and a creepage distance of 3.0 mm at
240 VAC)
Note: Overvoltage category II, pollution degree 1 if the Timer is
mounted to the PL11 Socket.
