MOUNTING INSTRUCTIONS Rated Load Current 20: 20 Amps 30: 30 Amps 35: 35 Amps [High I2t] (AC Output only) V Load - ■ Important Considerations ♦ Be sure to use input and output voltages within + Load (B) 0.89 in [22.5 mm] Minimum operating ranges. ♦ LED indicates only input status. It does not represent output status. ♦ To achieve maximum ratings, there must be a minimum spacing of 0.89 in (22.5 mm) between the devices in free air (as shown in fig.2). ♦ Protective Earth (PE) screw type recommended is 10-32 UNC standard, not provided with SSR. Through the use of a DIN rail ground (protective conductor) terminal block, the DIN rail itself can be used as the grounding bus bar. In this case, the zinc plated steel material used for the DIN rail clip of DR22 models, permits a secure path to ground and avoid the need of a further PE connection (see fig.3). fig. 2 Multiple units mounting for maximum ratings fig. 3 DR22 model with Protective Earth screw * Tests performed on Stranded wire TABLE 3.

This provides for the insertion and use of a ring or lug type wire terminal. ■ To install, make sure screw is completely lifted to maximum position, and insert Pin terminal (as shown in fig. 5) ■ A #2 Phillips head driver should be used with the Elevator Screws. If a powered driver is used, avoid speeds above 500 RPM. ■ Once installed, tighten terminal screws. Maximum ■ Cutting threads in the cover plastic as the screw elevates recommended screw torque is 14 in-lb(1.58 Nm). Be sure to apply sufficient downward pressure while tightening the terminal screws to prevent the screw assembly from lifting. is key to the elevating feature. It has a finite life and therefore not recommended to be used more than 50 times during the product lifetime. ■ Do not continue rotating the screw (in the elevating direction) once it freely rotates at the top of the plastic surface. The Elevator screw is capable of clearing 0.125 inches between the terminal and the bottom of the screw. Insertion of a terminal or lug thicker than 0.125 in is not recommended. ■ When inserting the terminal ensure that the terminal hole is in line with the screw. fig. 4 Elevator screw ■ During tightening, be certain that the terminal is seated flat within the cavity, and that the clamping washer is secure against the upper surface of the terminal. ■ If fork terminations, spade lugs, or stranded wire are used, to prevent improper contact do not raise the elevator screw out of the mating threads. fig. 5 Pin Terminal DERATING CURVES (C) DR2260x20x 10 5 20 30 40 50 60 70 Ambient Temperature (ºC) 25 20 15 10 5 0 80 Load Current (Amps) Load Current (Amps) Load Current (Amps) 30 15 0 20 30 80 20 30 40 50 60 70 Ambient Temperature (ºC) 80 30 Load Current (Amps) 20 15 10 5 0 40 50 60 70 Ambient Temperature (ºC) 35 30 25 20 15 10 5 0 DR2220D30U DR2220D20U Load Current (Amps) DR2260x35x DR2260x30x 20 20 30 40 50 60 70 Ambient Temperature (ºC) 80 25 Single unit 20 15 Multiple units, no minimum spacing between components (see fig. 2) 10 5 0 20 30 40 50 60 70 Ambient Temperature (ºC) 80 DANGER / DANGER / GEFARH / PELIGRO / PERICOLO / STROMSCHLAG-, EXPLOSIONS- ODER LICHTBOGENGEFAHR HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH RISQUE D'ELECTROCUTION, D'EXPLOSION OU D'ARC ELECTRIQUE • Turn off power supply before working on this equipment. • Coupez l'alimentation avant de travailler sur cet appareil. • Vor dem Arbeiten an dem Gerät dessen Stromversorgung abschalten.
