First screw the lower 2 screws into the mounting plate①, make sure that the two screws protrude at least 1.5 cm (for size 4, at least 2 cm), and then use the included handle to place the Siemens 3RW55 soft starter from above to the lower 2 On the screws ②. Finally, tilt the 3RW55 soft starter up so that it is close to the horizontal surface of the mounting plate ③, and tighten all 4 screws ④.

●Installation steps with lifting device:

Screw the lower two screws into the mounting plate ①, making sure that both screws protrude at least 2 cm. Use the 4 hooks of the lifting device to hook the holes provided on the 3RW55 soft starter. Place the 3RW55 soft starter from above on the 2 screws ② below. Tilt the 3RW55 soft starter upward so that it is close to the horizontal surface of the mounting plate ③, and tighten all 4 screws ④.

◆Install the fan cover

Claim:

1. Screwdriver T20.

2. A fan cover of appropriate size.

●The specific operation steps are shown in the figure below.

Transmitter|Encoder|Soft starter|Power supply|VFD|Light curtain|Servo products|Human-machine interface|Solenoid valve|Cylinder|Actuator|Flow meter|Transformer|Thyristor|Sensor|Deceleration drive gearbox reducer|Linear guide|Circuit breaker|Refrigeration compressorAll industrial products of okplazas are purchased from the original factory or formal channels of agents to ensure the original authenticity, which perfectly solves the problem of industrial product sample procurement and small-batch procurement for the majority of engineers and purchasing personnel.

Place the fan cover on the fan ①, and then tighten the fan cover ②. Size 1 soft starter: 1 fan cover and 4 screws are required. Soft starters of sizes 2 and 3: 2 fan covers are required. According to the design, each fan cover requires 3 screws. Size 4 soft starter: 1 fan cover and 4 screws are required. The fan cover can enhance contact protection and prevent the fan from being blocked by foreign objects.

◆Install high-performance 3RW5 HMI in Siemens soft starter 3RW55

Claim:

1. High-performance 3RW5 HMI.

2. HMI connection cable 0.1m (accessory).

●The specific operation steps are shown in the figure below

Transmitter|Encoder|Soft starter|Power supply|VFD|Light curtain|Servo products|Human-machine interface|Solenoid valve|Cylinder|Actuator|Flow meter|Transformer|Thyristor|Sensor|Deceleration drive gearbox reducer|Linear guide|Circuit breaker|Refrigeration compressorAll industrial products of okplazas are purchased from the original factory or formal channels of agents to ensure the original authenticity, which perfectly solves the problem of industrial product sample procurement and small-batch procurement for the majority of engineers and purchasing personnel.

Pay attention to the coding on the plug and socket ①+③, and pay attention to the cable routing: ①to the right cable routing, ③to the left cable routing.

◆Replace the hinged cover of Siemens 3RW55 soft starter

Note: The HMI display is damaged.

Ensure that the HMI display is not damaged when replacing the rotating cover.

●The specific operation steps are shown in the figure below.

Open the rotary cover ① at an angle of about 20, and loosen the hinge perpendicular to the soft starter plane ②+③ from the bottom. Remove the cover from the 3RW55 soft starter and install the replacement rotary cover in the reverse order.

Siemens soft starter 3RW55 removed

◆Remove high-performance 3RW5 HMI

Claim:

1. Flat head screwdriver.

Note: If the sealing surface is damaged, make sure that the sealing surface is not damaged by a screwdriver.

●The specific operation steps are shown in the figure below.
