WIRING PROCEDURES
Wiring should be implemented in accordance with
the following procedures. these procedures dis-
agree with local electrical codes, the local codes
should be followed instead. After completing wiring,
check that all wires have been properly connected.
CAUTION:
Incorrect
mav cause damaae to
the inverter and/or result in improper operation.
The Main Circuit Terminal Block is located at the
bottom portion of the inverter. The Control Circuit
Terminal Block is located near the middle of the
inverter. (See Figure 4-l)
NOTE:
and
terminals are
together at the factory. A DC Reactor is also shipped
for connection between terminals
on 100 HP
and above.
MAIN CIRCUIT WIRING
CAUTION:
Be sure that the power
is never
connected to the U, W terminals nor the N,
and
P terminals. Never connect N to
nor N to P.
Power
Connections
1 . Connect a circuit breaker between the three-phase
power supply and main circuit terminals ,
L3
(see Figure 4-2).
An AC Line Reactor may be required for some
applications. (See
Line Reactor Connec-
tion” paragraph in this section.)
2. If a starter or contactor is used between the circuit
breaker and the main circuit terminals to shut off
power to the inverter if an inverter fault occurs,
then wire control power as shown in Figure 43.
NOTE: See TABLE 2 for description of all terminals
and TABLE 3 for application wiring list.
NOTE: An MC Contactof (see figure 4-3) should be
used when either:
(7) A dynamic braking option is installed.
(2)
supply lines can experience an
voltage condition.
if the current rating of the MC Contactor coil is too
large for the Fault Relay Contacts, be sure to use a
pilot relay as shown in Figure
