Precautions
J SETTING CHANGES
J POWER SUPPLIES
Note: To avoid malfunction, do not change the time unit, time
scale, operating mode, or output type selector switch
while the Timer is in operation.
The H3DE Series is provided with a transformerless power
supply system. An electric shock may be received if the input
terminal or the output type selector switch is touched while power
is being supplied.
J MOUNTING/REMOVING
The H3DE should be mounted as horizontally as possible.
When mounting the H3DE on a socket mounting track, hook
portion (A) of the Timer to an edge of the track first, and then
depress the Timer in the direction of (B).
Use the bar terminal for wiring the H3DE. Using a stranded-wire
terminal may cause a short-circuit due to a stray wire entering
into the Timer.
Both AC and DC power supplies can be connected to the power
input terminals without regarding polarity.
With the H3DE only, a DC power supply must be connected to
the power input terminals as designated according to the polarity
of the terminals.
(A)
(B)
When removing the H3DE, pull out portion (C) with a flat-blade
screwdriver and remove the Timer from the mounting track.
A DC power supply can be connected if its ripple factor is 20% or
less and the mean voltage is within the rated operating voltage
range of the Timer.
Connect the power supply voltage through a relay or switch in
such a way that the voltage reaches a fixed value at once or the
Timer may not be reset or a timer error could result.
For the power supply of an input device, use an isolating
transformer, of which the primary and secondary windings are
mutually isolated and the secondary winding is not grounded.

surface of other equipment located below the H3DE.

J MOUNTING CLEARANCE
J INPUT/OUTPUT
If the load current is continuously being supplied to the Timer for
a long period of time, be sure to provide the mounting clearance
as shown in the figure below. If used under conditions without
this mounting clearance, an excessive rise in the internal
temperature of the components may result in a shortened
component life.

A2
Since the input circuit and the power supply circuit are
configured independently, the input circuit can be turned on or off
irrespective of the on/off state of the power supply. Note that a
voltage equivalent to the power supply voltage is applied to the
input circuit.
A Relay or Transistor as an External
Signal Input Device
When connecting a relay or a transistor as an external signal
input device, consider the following points (exemplified in the
diagrams that follow) to prevent short-circuiting due to a sneak
current to the transformerless power supply.
If a relay or transistor is connected to two or more Timers, the
input terminals of those Timers must be wired properly so that
they will not be different in phase, or the terminals will be
short-circuited to one another (refer to the figures below).

J INPUT WIRES
J RELAY LIFE EXPECTANCY
The input wires must be as short as possible. If the floating
capacity of wires exceeds 2,000 pF (approx. 17 m for cables with
120 pF/m), the operation will be affected. This is particularly
important to note when using shielded cables.
Built-in relay for the H3DE: G6RN; 50,000 operations min.
(8 A at 250 VAC, resistive load at 360 operations/h.)
J VDE CONFORMANCE
The H3DE as a built-in timer conforms to VDE 0435/P2021
provided that the following conditions are satisfied:
The output section of the H3DE is provided only with basic
isolation. To ensure reinforced isolation required by the VDE
standards, provide supplementary basic isolation on the load side
connected to the output.
The H3DE itself is designed according to the following:
•
•
Overvoltage category III
Pollution degree 2
The following facts are based on the above standards:
• Operation parts on the front and bottom: Reinforced isolationwith clearance of 5.5 mm and creepage distance of 5.5
mm at 230 VAC
• Output: Basic isolation with clearance of 3 mm and creepage
distance of 3 mm at 230 VAC
J ENVIRONMENT
When using the Timer in an area with excess electronic noise,
separate the Timer, wiring, and the equipment which generates
the input signals as far as possible from the noise sources. To
further prevent electronic interference, shield the input signal
wiring.
Organic solvents (such as paint thinner), as well as very acidic or
basic solutions, can damage the outer casing of the Timer.
Do not use the Timer in places where it is exposed to dust,
corrosive gas, or direct sunlight.
When storing the Timer, ensure that the ambient temperature and
humidity are within the rated values. Leave the Timer at room
temperature for at least three hours before using the Timer if it
has been stored at an ambient temperature of --10°C or below.
NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters to inches divide by 25.4.
