WIRING
SWH-4x00 models have twelve terminals as noted in Table 3. The terminal
strip is removable for easy installation and wiring. 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.
