For the best results with the L100 Series inverter, carefully read this manual and all of
the warning labels attached to the inverter before installing and operating it, and follow
the instructions exactly. Keep this manual handy for quick reference.
A safety instruction (message) includes a hazard alert symbol and a signal word,
WARNING or CAUTION. Each signal word has the following meaning:
HIGH VOLTAGE: This symbol indicates high voltage. It calls your attention to items
or operations that could be dangerous to you and other persons operation this equipment.
Read the message and follow the instructions carefully.
This symbol is the "Safety Alert Symbol." It occurs with either of two signal words:
CAUTION or WARNING, as described below.
WARNING: Indicates a potentially hazardous situation which, if not avoided, can result
in serious injury or death.
CAUTION: Indicates a potentially hazardous situation which, if not avoided, can result
in minor to moderate injury, or serious damage to the product. The situation described in
the CAUTION may, if not avoided, lead to serious results. Important safety measures
are described in CAUTION (as well as WARNING), so be sure to observe them.
Step 1: Indicates a step in a series of action steps to accomplish a goal.
NOTE: Notes indicate an area or subject of special merit, emphasizing either the
product's capabilities or common errors in operation or maintenance.
TIP: Tips give a special instruction that can save time or provide other benefits while
installing or using the product. The tip calls attention to an idea that may not be obvious
to first-time users of the product.
HIGH VOLTAGE: Motor control equipment and electronic controllers are connected to
hazardous line voltages. When servicing drives and electronic controllers, there may be
exposed components with housings or protrusions at or above line potential. Extreme
care should be taken to protect against shock.
Stand on an insulating pad and make it a habit to use only one hand when checking com-
ponents. Always work with another person in case an emergency occurs. Disconnect
power before checking controllers or performing maintenance. Be sure equipment is
properly grounded. Wear safety glasses whenever working on electronic controllers or
rotating machinery.
