3.3 Electrical Installation
3.3.1 Wiring guidelines
A.
Power Cables
Power cables are connected to TM1 terminal block, terminals L1, L2, L3, T1, T2, T3, P, R.
Choose power cables according to the following criteria:
(1)Use copper wires only. Correct wire diameters should be based on ratings at 105
o
C.
(2)For rating voltage of wires, the minimum voltage of 200V class type is 300V, and 400 V class
type is 600V.
B.
Control Cables
Control cables are connected toTM2 control terminal block.
Choose control cables according to the following criteria:
(1)
Use copper wires only. Correct wire diameters should be based on ratings at 105
o
C.
(2)
For rating voltage of wires, the minimum voltage of 200V class type is 300V, and 400 V class
type is 600V.
(3)
To avoid noise interference, do not route power and control cables in the same conduit or
trucking.
(4)
Where possible use screened / shielded control cables to minimizes electromagnetic
interference.
(5)
To avoid ground loops always earth the shield of control cables at one end only.
C.
Nominal electrical specifications of the terminal Block TM1:
※
Note: Nominal values of input and output signals (TM2
，
TM3) – follow the specifications of
class 2 wiring.
D.
Fuse types
Drive input fuses are provided to disconnect the drive from power in the event that a component
fails in the drive’s power circuitry. The drive’s electronic protection circuitry is designed to clear
drive output short circuits and ground faults without blowing the drive input fuses. Table below
shows the E310 input fuse ratings.
To protect the inverter most effectively, use fuses with current-limit function.

Notice
To avoid shock hazards, do not touch any electrical component when the power is applied or
with in five minutes after the power is disconnected. Any inspection should be performed after
the charge indicator goes off.
Do not perform wiring on the inverter with power on. Disregard of this notice may result in
serious injury.
