Receiving and Installation

Receiving & Inspection Baldor Controls are thoroughly tested at the factory and carefully packaged for shipment. When you receive your control, there are several things you should do immediately.

1.Observe the condition of the shipping container and report any damage immediately to the commercial carrier that delivered your control.

2.Remove the control from the shipping container and remove all packing materials. The container and packing materials may be retained for future shipment.

3.Verify that the part number of the control you received is the same as the part number listed on your purchase order.

4.Inspect the control for external physical damage that may have been sustained during shipment and report any damage immediately to the commercial carrier that delivered your control.

5.If the control is to be stored for several weeks before use, be sure that it is stored in a location that conforms to published storage humidity and temperature specifications stated in this manual.

Location Considerations The location of the control is important. Installation should be in an area that is protected from direct sunlight, corrosives, harmful gases or liquids, dust, metallic particles, and vibration. Exposure to these can reduce the operating life and degrade performance of the control.

Several other factors should be carefully evaluated when selecting a location for installation:

1.For effective cooling and maintenance, the control should be mounted on a smooth, non-flammable vertical surface.

2.At least 0.6 inches (15mm) top and bottom clearance must be provided for air flow. At least 0.4 inches (10mm) clearance is required between controls (each side).

3.Altitude derating. Up to 3300 feet (1000 meters) no derating required. Derate the continuous and peak output current by 1.1% for each 330 feet (100 meters) above 3300 feet.

4.Temperature derating. From 0° C to 40° C ambient no derating required. Above 40° C, derate the continuous and peak output current by 2.5% per ° C above 40° C. Maximum ambient is 50° C.

Mechanical Installation

Mount the control to the mounting surface. The control must be securely fastened to the mounting surface by the control mounting holes. The location of the mounting holes is shown in Section 7 of this manual.
