P345MTR and P345KPMTR Readers Installation Manual
Wiring
P345MTR 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.
