Verifying Product

Verify that the device reference marked on the label conforms to the

delivery note corresponding to the purchase order.

Open the packaging and check that the device has not been damaged in

transit.

Contact the distributor or SINEE directly for any quality issue.

Safety Information

The addition of this symbol to a Danger or Warning safety

label indicates that an electrical hazard exists, which will

result in personal injury if the instructions are not followed.

This is the safety alert symbol. It is used to alert you to

potential personal injury hazards. Obey all safety messages

that follow this symbol to avoid possible injury or death.

Safety Precautions

Danger

1. Wiring must be performed by authorized and qualified personnel.

2. Wait 5~10 minutes for capacitor discharge after disconnected from

power supply.

3. Electrical hazard exists in the parts of braking unit after power-on.

Failure to follow the instructions will result in fatal injury.

Caution

1. Well connect positive/negative poles of braking unit DC bus.

Otherwise, devices damage and fire may occur.

2. Locate the braking unit in a place with good ventilation, and keep the

ambient temperature lower than 40℃.

Overheating may result in fire or other accidents.

3. Always tighten the screws and gaskets inside the braking unit.

Any loosen may result in devices broken.

4. Be sure that housing is well located.

Remarks:

When BR100-160 and BR100-220-6 are in minimum resistance, and when

brake duty ratio D≤33%, braking unit can work continuously, it needs to

work discontinuously when brake duty ratio D>33%. Otherwise, braking

unit will trip over-heating protection.

4. Considerations for Installation Site

4.1 Considerations for Installation Site

No water drops

Clean and dry

No corrosive gas and liquid

No dust and metal particles

Ambient temperature: -10C～40C

Humidity: 20% RH～90% RH(no condensation)

Firm and steady installation base

No electromagnetic interference

Install a cooling fan or air-conditioner to keep the ambient

temperature in a maximum of 40ºC if the braking unit is installed in

a cabinet.

4.2 Installation Space

See Figure 4-1 for installation space of the braking unit.

BR100

Figure 4-1 Installation Dimensions

If multi-braking units are mounted in vertical parallel, the distance should

be in a minimum of 200mm, and a baffle is required for heat resistance

between 2 braking units. See Figure 4-2 for installation.

User Manual

BR100 Braking Unit

Figure 4-2 Parallel Installations for 2 Braking Units

Locate the braking unit in a place with good ventilation. A cooling fan

must be fitted at appropriate location in the cabinet for heat

dissipation. The braking resistor must be installed in a separate cabinet and

cannot be installed with the inverter, braking unit or other devices because

it will generate high heat. The distance between braking resistor and other

devices requires more than 2 meters. Otherwise, other devices may be

damaged.
