(A height of no more than half the SSR's height is recommended) G3PB G3PB Airflow Mounting surface Duct Height Please observe the following precautions to prevent failure to operate, malfunction, or undesirable effect on product performance. Mounting surface ■ Precautions for Correct Use Duct or airflow obstruction 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 obstruction Panel Note: Make sure that the load current is 50% of the rated load current when the G3PB is mounted horizontally. Ventilation outlet G3PB G3PB G3PB Close Mounting Air inlet SSR Mounting Pitch 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. Panel Mounting Between duct or airflow obstruction and SSR Duct or airflow obstruction SSR 60 mm min. Mounting direction Host and slave Vertical direction 30 mm min. 80 mm min. Close mounting 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.) Load current (A) 15 A Required number of fans 0.23 per SSR 25 A 0.39 35 A 0.54 45 A 0.70 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. J-44 Solid State Relays (Single-phase) G3PB Wiring • When using crimp terminals, refer to the terminal clearances shown below.

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.

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. Solid State Contactors (Three-phase) G3PB J-57 SSR Panel Wiring Tightening Torque When using crimp terminals, refer to the terminal clearances shown below. 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. Output Terminals Input Terminals Item Screw terminal diameter Tightening torque Input terminal M3.5 0.59 to 1.18 N·m Output terminal M4 0.98 to 1.47 N·m M5 1.47 to 2.45 N·m M4 (15 A, 25 A) M5 (35 A, 45 A) • 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. To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527. Cat.
