Unpacking and Inspection
Please take a few moments to unpack your new WJ200 inverter and perform these
steps:
1. Look for any damage that may have occurred during transportation.

Main Physical Features
The WJ200 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
to enhance heat sink performance. The mounting
holes are predrilled in the heat sink for your
convenience. Smaller models have two mounting
holes, while larger ones have four. Be sure to use all
the mounting holes provided.
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.
Inverter Keypad – The inverter uses a digital
operator interface, or keypad. 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 control
monitor operation. The ESC, SET,

and

keys
allow an operator to navigate to the inverter’s
functions and parameter values. The SET key is
used when changing a parameter.
