Wiring Precautions
For wiring and electrical connection, please pay much attention to the following:
•
Use 24V DC power supply with safety certification and self-protection function,
to avoid possible damage from wrong wiring.
•
For wire that is made for power supply or output port terminals, make sure the
terminal is well stannum-plated.
•
Use WEIHONG DB9 cable to ensure communication stability.
•
Length of the earthing cable should depend on technical requirements of the
electrical device. Generally, the shorter, the better.
•
The earthing cable for the terminal board must be separate with earthing
cables for device with high current load, for example, electric welding machine,
or motor.
•
In case that 24V DC power only supplies power for one 24V_A, maximum
output current for Y00~Y15 is 15A; in case that 24V DC power supplies power
for two 24V_A, maximum output current for Y00~Y15 can be greater than 15A.
•
In case that 24V DC power only supplies power for one 24V_B, maximum
output current for Y16~Y31 is 15A; in case that 24V DC power supplies power
for two 24V_B, maximum output current for Y16~Y31 can be greater than 15A.
