• When mounting, insert the Counter into
the cutout, insert the adapter from the
back and push in the Counter while
making the gap between the front panel
and the cutout panel as small as
possible. Use screws to secure the
Counter. If waterproofing is desired,
insert the waterproof packing.
• When several Counters are installed,
ensure that the ambient temperature
will not exceed specifications.
• The appropriate thickness of the panel
is 1 to 5 mm.

4. Wipe the back of the new Battery before inserting it.
5. Ensure that the + and – terminals are correctly oriented.
6. After replacing the Battery, re-insert the body into its case. (4)
Check that the case is securely held in by the lift-tab.
7. Press the Reset Key before use (not necessary for
H7ER-N,-NV,-NV1). (5)

EN/IEC Standards
The count or timer input, reset input, and backlight power supply ter-
minals of the no-voltage input or PNP/NPN universal DC voltage
input models (H7Ej-N,-N1, H7Ej-NV(-H),-NV1(-H)) are not isola-
ted.
A SELV power supply conforming to Appendix H of IEC61010-1
should be used for the count or timer input, reset input and backlight
power supply terminals. A SELV power supply is a power supply for
which the input and output have double or reinforced insulation, and
for which the output voltage is 30 Vrms with 42.4 V peak or 60 VDC
max. (Only the H7Ej-NVj-H has a backlight.)
The terminals for count or timer input and reset input for AC/DC mul-
ti-voltage input models have basic insulation.
Connect the reset input terminals to a device that does not have
exposed current-carrying parts and has basic insulation for
240 VAC.
Others
If the indicator keeps flickering or is OFF, the internal battery may be
close to the end of its service life. In such a case, it is suggested that
the battery be replaced.

Power Supply
• Use the power supply within the applicable range indicated by
the following waveform, while considering the ripple and voltage
fluctuations of the circuit power source.
Voltage
3.6 V
2.6 V
Battery Replacement
To prevent unwanted reset when replacing the battery, connect the
new battery before disconnecting the old one. Otherwise, the volt-
age supplied to the counter circuit drops, causing the present count
value to reset.
When designing the circuit board, providing two extra terminals for
battery connection will make the switch must simpler. See the sche-
matic diagram below:
• The H7Ej-NjP changes its mode as shown below depending
on the applied supply voltage.

guideline
H7Ej-NjP
Wiring polarity must be carefully observed, in order to prevent per-
manent damage to the Counters. Exercise caution when inserting
the Counter in the socket, to prevent reversed polarity.
