Receiving, Inspection and Storage
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 carton. Inspect for shipping damage and report
any damage immediately to your commercial carrier.
3. Verify that the part number of the control you received is the same as the part
number listed on your purchase order.
4. If the control is to be stored for several weeks before use, be sure that it is
stored in a location that is clean, dry and free from corrosives and
contaminants. Storage temperatures must not exceed 140°F (60°C).
Be sure to read an become familiar with the safety notices in Section 1 of this manual.
Failure to observe the product safety notices can result in injury or equipment damage.
If you have questions, please contact your Baldor distributor. Do not proceed unless you
understand the installation and operation requirements and safety notices.
Physical Location The location of the soft start control is important. It should be installed in an area that is
protected from direct sunlight, corrosives, harmful gases or liquids, dust, metallic
particles, and vibration. Exposure to these elements 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 vertically
on a flat, smooth, non-flammable vertical surface. Heat dissipation of 3.3 watts
per running FLA of the motor must be provided. All factory supplied enclosures
provided adequate heat dissipation.
2. If the control is mounted in an enclosure, sufficient air flow must be provided.
The fan or blower must be rated for at least 0.8 cubic feet per minute for each
ampere of motor FLA rating.
3. Keep high voltage and low voltage wiring separated. If the conduits must
cross, be sure that they cross at 90° angles only.
1. Motor overload protection is required for starters that do not have an overload
protection device.
2. The multipurpose soft starter is suitable for use on a circuit capable of
delivering no more than the short circuit A
RMS
listed in Table 2-1.
3. A short circuit current and overcurrent devices are required for soft start
controls that do not have a circuit breaker or fusible disconnect switch.
AC Main Circuit
Protection Devices Be sure a suitable input power protection device is installed. Use the recommended circuit
breaker or fuses listed in Table 2-1. Wire sizes and protective device specifications are based
on the maximum output power rating of the control.
Power Disconnect A power disconnect should be installed between the input power service and the control for
a fail safe method to disconnect power. The control will remain in a powered-up condition until
all input power is removed from the control and internal voltages are depleted.
