■ Precautions for Correct Use
Duct or

Panel
Do not surround the SSR
with ducts, otherwise
the heat radiation of the
SSR will be adversely
affected.
Horizontal Mounting
Use short ducts.
If the ducts cannot be
shortened, place the
SSR on a metal
base so that it is not
surrounded by the
ducts.
Ventilation
Be aware of air flow
Duct or air flow

Note: Make sure that the load current is 50% of the rated load current

10 mm min.
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.
Please reduce the ambient temperature of SSRs.
The rated load current of an SSR is measured at an ambient
temperature of 25 or 40 °C.
An SSR uses a semiconductor in the output element. This causes
the temperature inside the control panel to increase due to heating
resulting from the passage of electrical current through the load. To
restrict heating, attach a fan to the ventilation outlet or air inlet of the
control panel to ventilate the panel. This will reduce the ambient
temperature of the SSRs and thus increase reliability. (Generally,
each 10 °C reduction in temperature will double the expected life.)

Example: For 10 SSRs with load currents of 20 A,
0.23 x 10 = 2.3
Thus, 3 fans would be required.
Size of fans: 92 mm2, Air volume: 0.7 m3/min,
Ambient temperature of control panel: 30 °C
If there are other instruments that generate heat in the control
panel other than SSRs, additional ventilation will be required.

• Make sure that all lead wires are appropriate for the current.
• Output terminals are charged even when the Relay is turned OFF.
Touching the terminals may result in electric shock. To isolate the
Relay from the power supply, install an appropriate circuit breaker
between the power supply and the Relay.
Be sure to turn OFF the power supply before wiring the Relay.
Tightening Torque
• Refer to the following and be sure to tighten each screw of the
Relay to the specified torque in order to prevent the Relay from
malfunctioning.

Safety Precautions
Since the Relay is heavy, firmly mount the DIN track and fix both
ends with End Plates for DIN-track-mounting models.
Applicable DIN Tracks
The G3PB can be mounted to TH35-15Fe (IEC60715) DIN tracks.
The manufacturers and models of DIN tracks to which mounting is
possible are shown in the following table.

■ Precautions for Correct Use
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.
Please reduce the ambient temperature of SSRs.
Panel
Note: Mount the G3PB so
that the markings
can be read.
Note: When the G3PB is
mounted horizontally,
use at 50% of the rated
load current.
Close Mounting
The rated load current of an SSR is measured at an ambient
temperature of 25 or 40 °C.
An SSR uses a semiconductor in the output element. This causes
the temperature inside the control panel to increase due to heating
resulting from the passage of electrical current through the load. To
restrict heating, attach a fan to the ventilation outlet or air inlet of the
control panel to ventilate the panel. This will reduce the ambient
temperature of the SSRs and thus increase reliability. (Generally,
each 10 °C reduction in temperature will double the expected life.)

Thus, 17 fans would be required.

If there are other instruments that generate heat in the control
panel other than SSRs, additional ventilation will be required.

Refer to the following and be sure to tighten each screw of the Unit to
the specified torque in order to prevent the Unit from malfunctioning.

• Make sure that all lead wires are thick enough for the current.
• Output terminals T1, T2, and T3 are charged regardless of whether
the Unit is a 2- or 3-element model that is turned on or off. Do not
touch these terminals, otherwise an electric shock may be
received.
To isolate the Unit from the power supply, install an appropriate
circuit breaker between the power supply and Unit.
Be sure to turn off the power supply before wiring the Unit.
• Terminal L2 and terminal T2 of the 2-element model are internally
short-circuited to each other. Therefore, connect terminal L2 to the
ground terminal side of the power supply. If terminal L2 is
connected to a terminal other than the ground terminal, cover all
the charged terminals, such as heater terminals, for the prevention
of electric shock accidents and ground faults.
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
