Operating and Storage Locations
Do not use or store the G3PB in the following locations. Doing
so may result in damage, malfunction, or deterioration of
performance characteristics.

Precautions for Correct Use
Before Actual Operation
1.
The G3PB in operation may cause an unexpected accident.
Therefore it is necessary to test the G3PB under the variety of
conditions that are possible. For example, the characteristics of
the G3PB must always be considered in terms of the differences
in characteristics between individual G3PBs.
2.
Unless otherwise indicated, the rated values in this catalog have
all been tested according to JIS C5442 standards in a
temperature range between 15
°
C and 30
°
C, a relative humidity
range between 25% and 85%, and an atmospheric pressure
range between 88 and 106 kPa. To confirm the ratings of specific
G3PBs, the same operating environment conditions must be pro-
vided in addition to the load conditions.
Mounting Method
Mount the DIN Track-mounting G3PBs firmly to the DIN Track and
secure End Plates on both sides to prevent the G3PB falling due to
its heavy weight. Also mount direct-mounting G3PBs securely in the
panel.
Note:
Make sure that the load current is 50% of the rated load current
when the G3PB is mounted horizontally. For details on close
mounting, refer to the related information under performance
characteristics.

Ventilation Outside the Control Panel
If the air inlet or air outlet has a filter, clean the filter regularly to
prevent it from clogging and ensure an efficient flow of air.
Do not locate any objects around the air inlet or air outlet, otherwise
the objects may obstruct the proper ventilation of the control panel.
A heat exchanger, if used, should be located in front of the SSR Units
to ensure the efficiency of the heat exchanger.

Do not surround the SSR
with ducts, otherwise

SSR will be adversely
affected.
Use short ducts.
If the ducts cannot be
shortened, place the

surrounded by the
ducts.
