Wiring The Power Supply - IDEC WB2F User Manual

1. Overview Installation & wiring
z Wiring the power supply
Connect pin number 5 (+ 5V) to the 5V DC power supply + side and pin number 9 (0 V) to the - side. Read the following
notes carefully and refer to the wiring example below before attempting to wire the power supply.
WB2F
Caution Caution
Do not reverse the power supply connections under any circumstances. Doing so may result
z
in damage.
Use the product within the rated power supply voltage range. Otherwise there is a risk of ex-
z
plosion or burnout.
When using this product in situations where it is not built into other equipment, do not use
z
an integrated power supply. Otherwise there is a risk of fire or electric shock.
Avoid parallel wiring of the product's wires in the same conduit or duct with high voltage
z
lines or power lines (inverter power lines in particular) as this may cause malfunction or dam-
age due to the effect of induction noise.
The power reset time is under 5s. Perform operations 5s after turning the power on.
z
Always turn off the WB2F's power supply before wiring the product.
z
If the wires are long and when there is a risk of being affected by power sources or solenoids, inde-
z
pendently wire the product as a general rule.
If you elongate the cable via a DIN connector, be careful of short circuit between adjacent terminals
z
and consider the subsequent voltage drop of the power supply and use a cable thicker diameter than
AWG28. If the entire cable exceeds a length of 2.8m, there is a possibility that the it will adversely effect
noise immunity. Do so only after thoroughly confirming that the WB2F's performance is not impacted.
z RS-232 wiring
When connecting the unit to a host device such as an operator interface or a computer via RS-232, wire it referring to the
following example.
