Safety

Deﬁnitions and Symbols

WARNING

This symbol indicates high voltage. It calls your

attention to items or operations that could be dangerous

to you and other persons operating 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).

Hazardous High Voltage

WARNING

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 components. 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.

CAUTION

Remove any External Start signals or permissives before

resetting the fault to prevent an unintentional restart of the

SVX9000/SPX9000, which could result in personal injury or

equipment damage.

WARNING

Before startup, observe the warnings and safety

instructions provided throughout this manual.

Internal components and circuit boards (except

the isolated I/O terminals) are at utility potential

when the SVX9000/SPX9000 is connected to the

line. This voltage is extremely dangerous and may

cause death or severe injury if you come in contact

with it.

When the SVX9000/SPX9000 is connected to the

utility, the motor connections U (T1), V (T2), W

(T3) and DC bus/brake resistor connections B–, B+,

and R– are live even if the motor is not running.

Do not make any connections when the AF drive is

connected to the utility line.

Do not open the cover of the AF drive immediately

after disconnecting power to the unit, because

components within the drive remain at a

dangerous voltage potential for some time. Wait

at least five minutes after the cooling fan has

stopped and the keypad or cover indicators are

dark before opening the SVX9000/SPX9000 cover.

The control I/O terminals are isolated from the

utility potential, but relay outputs and other I/Os

may have dangerous external voltages connected

even if power is disconnected from the SVX9000/

SPX9000.

Before connecting to the utility, make sure that

the cover of the drive is closed.
