2.2.2 Main circuit wiring
(1) Warning on wiring
When carrying out work on the inverter wiring make sure to wait for at least ten minutes before you
remove the cover. Be sure to verify that the charge lamp is not illuminated.
A final check should always be made with a voltage meter.
After removing the power supply, there is a time delay before the capacitors will dissipate their charge.
1 Main power terminals (R, S and T)
Connect the main power terminals (R, S and T) to the power supply through an electromagnetic
contactor or an earth-leakage breaker.
N700 recommends connecting the electromagnetic contactor to the main power terminals,
because when the protective function of the inverter operates, it isolates the power supply and
prevents the spread of damage and accident.
This unit is for a three-phase power supply. Be sure not to power a three-phase only inverter
with single phase power. Otherwise, there is the possibility of damage to the inverter and the
danger of fire.
If you require a single phase power supply unit, please contact your local HYUNDAI Branch.
The inverter enters into the following condition at the occurrence of open phase if it is selected
open phase protection is valid :
-
R phase, S phase or T phase, open phase condition:
It becomes single-phase operation condition. Trip operation, such as a deficiency voltage or
over current, may occur.
Don't use it under open phase condition. A converter module may be damaged as a result of
the following conditions. Use caution when
-
an unbalance of the power supply voltage is more than 3%
-
Power supply capacity is more than 10 times of the capacity of inverter and case beyond
500kVA.
-
A drastic change in the power supply
(Example) Turning on/off of the power supply should not be done more than three times in one
minute. It has the possibility of damaging the inverter.
2 Inverter output terminals (U, V, and W)
Using a heavier gauge wire can prevent the voltage drop.
Particularly when outputting low frequencies, the torque of the motor will be reduced by the
voltage drop of the wire.
Do not install power factor correction capacitors or a surge absorber to the output.
The inverter will trip or sustain damage to the capacitors or the surge absorber.
In the case of the cable length being more than 65 feet, it is possible that a surge voltage will be
generated and damage to the motor is caused by the floating capacity or the inductance in the
wire. When an EMC filter is to be installed, please contact your local HYUNDAI branch.
In the case of two or more motors, install a thermal relay to each motor.
Make the RC value of the thermal relay the value of 1.1 times of motor rated electric current.
3 External braking resistor connection terminals (P, RB)
The regenerative braking circuit (BRD) is built-in as standard
When braking is required, install an external-braking resistor to these terminals.
The cable length should be less than 16 feet, and twist the two connecting wires to reduce
inductance.
Do not connect any other device other than the external braking resistor to these terminals.
When installing an external braking resistor make sure that the resistance is correctly rated to
limit the current drawn through the BRD.
4 Earth Ground (G)
Make sure that you securely ground the inverter and motor for prevention of electric shock.
The inverter and motor must be connected to an appropriate safety earth ground and follow all
8

local electrical codes.
In case connecting 2 or more inverters, use caution not to use a loop which can cause some
malfunction of the inverter.

(2) Wiring
6 Both the CM1 and L terminals are insulated to both the common terminal of the input and output
signals. Do not short or connect to ground these common terminals.
7 Use twisted screened cable, for the input and output wires of the control circuit terminals.
Connect the screened cable to the common terminal.
8 Limit the connection wires to 65 feet.
9 Separate the control circuit wiring from the main power and relay control wiring.
10 When using relays for the FW terminal or an intelligent input terminal use a control relay that is
designed to work with 24Vdc.
11 Do not short the analog voltage terminals H and L or the internal power terminals PV24 and all
CM1’s. Otherwise there is risk of Inverter damage.

Operation
!
WARNING
Be sure not to touch the main terminal or to check the signal add or remove wires
and/or connectors.
Otherwise, there is a danger of electric shock.
Be sure not to turn the input power supply on until after front case is closed.
While the inverter is energized, be sure not to remove the front cover.
Otherwise, there is a danger of electric shock.
Be sure not to operate the switches with wet hands.
Otherwise, there is a danger of electric shock.
While the inverter is energized, be sure not to touch the inverter terminals even while
the unit is not running.
Otherwise, there is a danger of electric shock.
If the retry mode is selected, it may suddenly restart during the trip stop.
Be sure not to approach the equipment.(Be sure to design the equipment so that
personnel safety will be secured even if equipment restarts.)
Otherwise, there is a danger of injury.
Be sure not to select retry mode for up and down equipment or traveling equipment,
because there is an output free-running mode in term of retry.
Otherwise, there is a danger of injury and/or machine breakage
Even if the power supply is cut for a short period of time, the inverter may restart
operation after the power supply is restored if the operation command is given.
If a restart may incur danger to personnel, be sure to make a circuit so that it will not
restart after power recovery.
Otherwise, there is a danger of injury.
The stop key is valid only when a function is on. Ensure that there is a hard wired
emergency stop that is separate from the stop key of the inverter.
Otherwise, there is a danger of injury.
With the operation command on, if the alarm reset is ordered, the inverter can restart
suddenly. Be sure to set the alarm reset after checking the operation command is off.
Otherwise, there is a danger of injury.
Be sure not to touch the inside of the energized inverter or to put a bar into it.
Otherwise, there is a danger of electric shock and/or fire.
