2) Using the AC power supply with the minimum amount of the noise when suppling for the
Power Supply Module. Use an isolation transformer or a noise filter to prevent the noise
from penetrating into the product.
3) For the details of the input condition for the Power Supply Module, see 6.1.3 Functions
and Specifications of Power Supply Module.
E. Connecting Power Supply Wire
Caution Do not allow foreign matter such as cable chips into the Modules.
Foregn matter in the Modules may cause fire, failures and/or malfunctions.
1) Use power supply wires of 1.5 mm 2 (AWG16) to 2.5 mm 2 (AWG13) to connect to the field
wiring terminals and make sure they are twisted.
2) M4 Phillips screws are used on the field wiring terminals. Accordingly, use solderless
terminals for M4 Phillips screws for the cable ends.
3) When using and insulation transformer for the AC power supply, always separate the pri-
mary and secondary coils. When using a noise filter, also make sure to separate the pri-
mary and the secondary coils.
