5. Superimposed surge of power
supply (PM4H series common)
For the superimposed surge of power
supply, the standard waveform is taken
as the standard value for surge-proof
voltage.
If external surge occurs exceeding the
specified value, the internal circuit may
break down. In this case, use a surge
absorption element.
applied each five times between the
power pins.
The typical surge absorption elements
include a varistor, a capacitor, and a
diode. If a surge absorption element is
used, use an oscilloscope to see
whether or not the foreign surge exceed-
ing the specified value appears.
The positive and negative voltages are

6. Acquisition of CE marking
Please abide by the conditions below
when using in applications that comply
with EN61812-1.
1) Overvoltage category III, pollution
level 2
2) This timer employs a power supply
without a transformer, so the power and
input signal terminals are not insulated.
(PM4H-A only)
(1) When a sensor is connected to the
input circuit, install double insulation on
the sensor side.
(2) In the case of contact input, use dual-
insulated relays, etc.
3) The load connected to the output con-
tact should have basic insulation.
This timer is protected with basic insula-
tion and can be double-insulated to meet
EN/IEC requirements by using basic
insulation on the load.
4) Please use a power supply that is pro-
tected by an overcurrent protection
device which complies with the EN/IEC
standard (example: 250 V 1 A fuse, etc.).
PRECAUTIONS IN USING THE PM4H SERIES
5) You must use a terminal socket or
socket for the installation. Do not touch
the terminals or other parts of the timer
when it is powered. When installing or
un-installing, make sure that no voltage
is being applied to any of the terminals.
6) Do not use this timer as a safety cir-
cuit. For example when using a timer in a
heater circuit, etc., provide a protection
circuit on the machine side.
