Safety 1-3

General Safety Guidelines This section covers general safety guidelines for electronic devices.

Safety information specific to ULTRA 100 Series drives begins on

page 1-1.

Hazards which can be encountered in the use of this equipment are:

● Electric Shock

● Electric Fire

● Mechanical

● Stored Energy

There are no chemical or ionizing radiation hazards.

Electrical shock and fire hazards are avoided by using normal

installation procedures for electrical power equipment in an industrial

environment. Installation must be undertaken by suitably qualified

personnel. Note that this amplifier must be installed in an industrial

cabinet such that access is restricted to suitable qualified personnel.

Mechanical hazards are associated with potentially uncontrolled

movement of the motor shaft. If this imposes a risk in the machine,

then appropriate precautions must be made to electrically disconnect

the motor from the drive when personnel have access to moving parts

of the machine. Note also that the motor must be securely mounted at

all times.

Stored energy hazards are both electrical and mechanical.

1. Electrical hazards can be avoided by disconnecting the drive from

its power source and measuring the DC bus voltage to verify it has

reached a safe level or by waiting for the time indicated in the

warning on the front of the drive prior to removing the protective

covers or touching any connections.

2. Mechanical hazards require a risk analysis on the effects of stored

mechanical energy when the machine is running at speed, as well

as the potential for the conversion of electrical energy stored in the

drive being converted to mechanical energy. Electrical energy may

be stored in drive for the time indicated in the warning on the front

of the drive.

The following points should be observed for the safety of personnel:

● Only qualified personnel familiar with the equipment are

permitted to install, operate and maintain the device.

● System documentation must be available and observed at all

times.
