Precautions (Common)
Note:
The undermentioned is common for all H7GP/H7HP models.
Power Supplies
When turning the power ON and OFF, input signal reception is possi-
ble, unstable, or impossible as shown in the diagram below.
Apply the power supply voltage through a relay or switch in such a
way that the voltage reaches a fixed value immediately.
Although the H7GP/H7HP power supply (primary side) is isolated
from control circuits (secondary side) by a transformer, the primary
and secondary sides of the transformer are linked by a capacitor,
making it possible for high-frequency components to leak to the sec-
ondary side. Take adequate precautions against electrical shock. Do
not connect input circuits to exposed parts (such as the machine
body) and be sure that the power supply is turned off before wiring.
Self-diagnostic Function
The following displays will appear if an error occurs.
Flush Mounting
The panel surface is water-resistive (conforming to NEMA 4 and
IP66). In order to prevent the internal circuit from water penetration
through the space between the counter and operating panel, attach a
rubber packing between the counter and operating panel and secure
the rubber packing with the Y92F-3
@
flush-mounting adaptor.
Be sure the rubber packing is installed in the correct direction. The
wider portion must be facing the panel when installed, as shown in
the following illustration. Using a flat-head screwdriver, press in the
Mounting Adapter until it cannot be pressed in any further in order to
ensure water-resistive performance.
Other
Water resistance may deteriorate depending on the environment.
Periodically check water resistance.
Oil resistance is not applicable to all types of oil. Be sure to test any
specific oils before actual application.
Labels
Unit labels are included with the H7GP/H7HP and DIP switch labels
are included with the H7HP. Attach these labels as shown in the fol-
lowing illustrations.
Accessories
The accessories listed in the following table are included with the
H7GP/H7HP. Be sure you understand the use of these accessories
and use them correctly.
