WIRING
The SWH-4000 model has ten terminals as noted in Table 2. When
attaching wires to the connector, strip off only the minimum insulation
required (approx. 1/8'') and push the wire into the connector until the
insulation is flush or inside the connector body. This is particularly critical
for outdoor readers. While the reader itself is designed and protected to
IP65 standards, the cable wires can potentially corrode and short together if
not carefully mounted and tightly fastened in the connector body.
