■Ratings
Note: 1. Single-phase, full-wave-rectified power supplies can be used.
2. When using the H3YN continuously in any place where the ambient temperature is in a range of 45°C to 50°C, supply 90% to 110% of
the rated supply voltages (supply 95% to 110% with 12 VDC type).
3. Set the reset voltage as follows to ensure proper resetting.
100 to 120 VAC: 10 VAC max.
200 to 230 VAC: 20 VAC max.
100 to 110 VDC: 10 VDC max.

Precautions
■Correct Use
The operating voltage will increase when using the H3YN continu-
ously in any place where the ambient temperature is in a range of
45°C to 50°C. Supply 90% to 110% of the rated voltages (at 12 VDC:
95% to 110%).
Do not leave the H3YN in time-up condition for a long period of time
(for example, more than one month in any place where the ambient
temperature is high), otherwise the internal parts (aluminum electro-
lytic capacitor) may become damaged. Therefore, the use of the
H3YN with a relay as shown in the following circuit diagram is recom-
mended to extend the service life of the H3YN.
The H3YN must be disconnected from the Socket when setting the
DIP switch, otherwise the user may touch a terminal imposed with a
high voltage and get an electric shock.
Do not connect the H3YN as shown in the following circuit diagram
on the right hand side, otherwise the H3YN’s internal contacts differ-
ent from each other in polarity may become short-circuited.
Use the following safety circuit when building a self-holding or self-
resetting circuit with the H3YN and an auxiliary relay, such as an MY
Relay, in combination.
In the case of the above circuit, the H3YN will be in pulse operation.
Therefore, if the circuit shown on page 91 is used, no auxiliary relay
will be required.
Do not set to the minimum setting in the flicker modes, otherwise the
contact may become damaged.
Be careful not to apply any voltage to the terminal screws on the
back of the Timer. Mount the product so that the screws will not come
in contact with the panel or metal parts.
Do not use the H3YN in places where there is excessive dust, corro-
sive gas, or direct sunlight.
Do not mount more than one H3YN closely together, otherwise the
internal parts may become damaged. Make sure that there is a
space of 5 mm or more between any H3YN models next to each
other to allow heat radiation.
The internal parts may become damaged if a supply voltage other
than the rated ones is imposed on the H3YN.
In order to conform to UL and CSA requirements when using the
H3YN-4/-41 or H3YN-4-Z/-41-Z, connect the Unit so that output con-
tacts (contacts of different poles) have the same electric potential.
In cases such as PLC input where the load is extremely small for the
control output of a timer containing a power relay (using other than
gold-plated contacts), reliability can be increased by using contacts
of the same poles (e.g., the H3Y-2) in parallel.
■Precautions for EN61812-1
Conformance
The H3YN as a built-in timer conforms to EN61812-1 provided that
the following conditions are satisfied.
Handling
Do not touch the DIP switch while power is supplied to the H3YN.
Before dismounting the H3YN from the Socket, make sure that no
voltage is imposed on any terminal of the H3YN.
The applicable Socket is the PYF@A.
Only basic insulation is ensured between the Y92H-3 Hold-down
Clips and H3YN internal circuits.
Do not allow the Y92H-3 Hold-down Clips to contact other parts.
The insulation test voltage between different pole contacts for the 4-
pole model is the impulse voltage of 2.95 kV.
Wiring
The power supply for the H3YN must be protected with equipment
such as a breaker approved by VDE.
Basic insulation is ensured between the H3YN’s operating circuit and
control output.
Basic insulation: Overvoltage category II,
pollution degree 1 (H3YN-4/-41, H3YN-4-Z/-
41-Z), pollution degree 2 (H3YN-2/-21)
(with a clearance of 1.5 mm and a creepage
distance of 2.5 mm at 240 VAC)
