Unpacking and Inspection

Please take a few moments to unpack your new L100 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 L100 inverter

b.One Instruction Manual with self-adhesive label for the inverter

c.One L100 Quick-reference Guide

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

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

Main Physical Features

The L100 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 larger models include a fan(s) to enhance heat sink performance. The mounting holes are pre-drilled in the heat sink for your convenience. 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 during powered operation (power is On)

•Second-level access – for editing parameters and wiring control signals (power is On)

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

1.First-level Access - View the unit just as it came from the box as shown. The four-digit display can show a variety of performance parameters. LEDs indicate whether the display units are Hertz or Amperes. 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 control motor operation. These controls and indicators are usually the only ones needed after the inverter installation is complete. You can also access the modular jack for connecting a programming or monitoring device such as a PC (see Chapter 3). And, you can access the two chassis GND screws on the metal tab at the bottom of the inverter.
