START-UP
Alternate Wire Lugs —
In the case where the incoming
power wire size does not fit the standard lug, alternate lugs may
be used. See Table 1. Note that lugs rated for a higher current
than the circuit breaker may be used.

DANGER
Internal components and circuit boards of the drive are live
when the drive is connected to incoming power. Coming
into contact with this voltage is extremely dangerous and
will result in severe personal injury or death.
The motor terminals U, V, W and the DC-link/brake resis-
tor terminals B+/R+, R- are live when the drive is con-
nected to incoming power, even if the motor is not running.
Do not make any connections when the drive is connected
to the incoming power.
After having disconnected the drive, wait until the indica-
tors 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 drive connections. Do not even
open the cover before this time has expired..
Before connecting the drive to the incoming power, make
sure that the switchgear enclosure door is closed.
WARNING
The control I/O-terminals are isolated from the mains
potential. However, the relay outputs and other I/O termi-
nals may have a dangerous control voltage present even
when the drive is disconnected from incoming power.
Coming into contact with this voltage could result in severe
personal injury.

CAUTION
If other than refrigerant cooling is used, before connecting
the drive to the incoming power, make sure that the coolant
is circulating and has no leaks.
CAUTION
When working with the Drive Explorer, never use the
Rotate function as the motor will immediately start and
severe compressor damage could result.
