START-UP Alternate Wire Lugs
If the incoming power wire size does not fit the standard lug, alter-
nate lugs may be used. See Table 1. Note that lugs rated for a high-
er 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 resistor
terminals B+/R+, R- are live when the drive is connected to in-
coming 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 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 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 poten-
tial. However, the relay outputs and other I/O terminals 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 cir-
culating and has no leaks.
CAUTION
When working with the Drive Explorer, never use the Rotate
function as the motor will immediately start and severe com-
pressor damage could result.
