l
Do not place the main power AC line input supplies and signal wires in close proximity. Do not tie
wrap them and not put in the same duct.
l
The Driver Unit and the noise filters must be close to each other and wiring must be of minimal
length. Do not insert contacts like a magnetic switch or a relay between them.
l
Install a circuit breaker on the main power AC line. When the power is turned “ON”, an inrush
current to the circuit will occur because of the capacitive load connected to the main power supply
circuit.
l
When inserting contacts into the power supply circuit, the specification of the contact should be
greater or equal to ones in the following table:
Table 6-5 : Contact Requirements
Contacts For ESA Type
No-Fuse Breaker
Current Rating 15A
Short-Circuit Breaker
Contact Capacity 15A
Sensitivity 15mA
Magnetic Switch
Contact Capacity 30A
Table 6-6 : Inrush Current
Inrush Current (TYP)
Item
AC100V AC200V
Control Power
7A 14A
Main Power
80A 140A
l
Install a surge killer circuit for magnet switches, relays and solenoids.
l
When replacing the fuse F1 or F2 of the Driver Unit, use the fuse provided with the Driver Unit.
Caution : • Use the R-S terminals when connecting single-phase 200 VAC for the main
power supply. Surge current becomes larger when the R-T terminals are in
use.
• During wiring, be careful not to loose terminal block screws, etc.
Danger : Install the plastic protection on TB Terminal Block after wiring. The terminals
on TB will be at high voltage when power is turned on. Removing the protection
and touching terminals may cause extreme electrical shock.
Note : Refer to “5. Connector Specification” for the connector wiring.
