Precautions
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 1
10%).
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 elec-
trolytic
capacitor) may become damaged. Therefore, the use of the
H3YN
with a relay as shown in the
following circuit diagram is rec
-
ommended
to extend the service life of the H3YN.
MY Relay
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 dif
fer-
ent
from each other in polarity may become short-circuited.
Correct Incorrect
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.
Auxiliary relay:
MY Relay
: H3YN
In the case of the above circuit,
the H3YN will be in pulse operation.
Therefore, if the circuit shown on page
11
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 oth
-
er
to allow heat radiation.
The
internal parts may become damaged if a supply voltage other
than the rated ones is imposed on the H3YN.
Precautions for VDE Conformance
The
H3YN as a built-in timer conforms to VDE 0435/P2021 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.
Wiring
The
power supply for the H3YN
must be protected with equipment
such
as a breaker approved by VDE.
Only
a load with basic isolation can be connected to the output con
-
tact.
The H3YN is a model with basic isolation. Therefore, the H3YN
and the load will ensure reinforced isolation, thus meeting VDE
standards.
Insulation
requirement:
Overvoltage category II,
pollution degree 2
(with a clearance
of 1.5 mm and a creep
-
age distance of 2.5 mm at 240 V
AC)
Output terminals next to each other on the H3YN-4, H3YN-41,
H3YN-4Z,
or H3YN-41-Z must have the same electric potential.
