Unpacking and InspectionMain Physical Features

Please take a few moments to unpack your new SJ300 inverter and perform these steps:

1.Look for any damage that may have occurred during shipping.

2.Verify the contents of the box include:

a.One SJ300 inverter

b.One Instruction Manual (supplied by printed book for –FU/–FR models, supplied on CR-ROM for –FE models)

c.One SJ300 Quick Reference Guide

d.One packet of desiccant—discard (not for human consumption)

3.Inspect the specifications label on the front or side of the inverter. Make sure it matches the product part number you ordered.

The SJ300 Series inverters vary in size according to the current output rating and motor size for each model number. All feature the same basic keypad and connector interface for consistent ease of use. The inverter construction has a heat sink at the back of the housing. The fans enhance heat sink performance. Mounting holes are pre-drilled in the heat sink for your conve- nience. Never touch the heat sink during or just after operation; it can be very hot.

The electronics housing and front panel are built onto the front of the heat sink. The front panel has three levels of physical access designed for convenience and safety:

•First-level access – for basic use of inverter and editing parameters during powered opera- tion (power is ON)

•Second-level access – for wiring the inverter power supply or motor (power is OFF)

•Third-level access – for accessing the expansion bay for adding/removing expansion boards (power is OFF)

1.First-level Access - View the unit just as it came from the box as shown. The OPE-SRE or OPE-S digital operator keypad comes installed in the inverter. The four-digit display can show a variety of performance parameters. LEDs indicate whether the display units are Hertz, Volts, Amperes, or kW. Other LEDs indicate Power (external), and Run/Stop Mode and Program/Monitor Mode status. Membrane keys Run and Stop/Reset, and a Min/Max frequency control knob (OPE-SRE only) control motor operation. These controls and indicators are usually the only ones needed after the inverter installation is complete.

The FUNC., 1 , 2 , and STR keys allow an operator to change the inverter’s functions and parameter values, or to select the one monitored on the 4-digit display. Note that some parameters may not be edited if the inverter is in Run mode.
