Chapter 6 — Start-Up

Safety Precautions

Before start-up, note the following directions and warnings:

WARNING

Internal components and circuit boards of the inverter

(except for the galvanically isolated I/O terminals) are live

when the inverter is connected to mains potential. Coming

into contact with this voltage is extremely dangerous and

may cause death or severe injury.

The motor terminals U, V, W and the DC-link/brake resistor

terminals+/- are live when the inverter is connected to DC

supply, even if the motor is not running.

The control I/O-terminals are isolated from the mains

potential. However, the relay outputs and other I/O-

terminals may have a dangerous control voltage present

even when the inverter is disconnected from DC supply.

Do not make any connections when the inverter is

connected to the DC supply.

After having disconnected the inverter, wait until the fan

stops and the indicators on the keypad go out (if no keypad

is attached see the indicator through the keypad base). Wait

5 more minutes before doing any work on inverter

connections. Do not open the cover before the time has

expired.

Before connecting the inverter to DC supply, make sure that

the inverter’s front cover is closed.

When running, the side of inverter FR8 is burning hot. Do

not touch it with bare hands!

When running, the back of inverter FR6 is burning hot.

Therefore it MUST NOT be mounted onto a surface which is

not ﬁreproof.
