Connect low-voltage power to the lower 2 screws on the
terminal block. The LTR-RSS requires a voltage source of
9 to 24 volts, AC or DC. If the distance between the
LTR8-512 Master and the LTR-RSS is less than 100ft, you
can use a 2nd twisted-pair in the cable to bring power from
the Master Terminals # 12 and 13 (on the rear of the
Master's Display Panel, providing 12vAC at 250mA). You
should use a separate low-voltage power supply or
transformer if the cable would be longer than 100 feet or
placed in areas of electrical interference that can cause
problems for the Master. You should also place an in-line
250ma fuse on this connection.
Secure the cover-plate to the electrical box with four 6-32
FH screws.
