STEP 11: Connecting Multiple TAS250 on the Same Telephone Line (optional)
It is very important to take into consideration that a maximum of 305 m (1000 ft) should be used between the first
TAS250 and the last TAS250, or in total.
STEP 12: Connect the TAS250 to Earth Ground
Since the TAS250 uses high performance communication and the telephone line, proper grounding is required to
insure safety and proper operation. An AWG #18 single conductor copper wire must be used to ground each TAS250
to good earth ground as per the local electrical code (be careful with ground loops). The ground clamp should be
located below any other ground.
STEP 13: Connect AC Power
Power should only be applied to the unit when all connections are completed. Connect the
16VAC
terminals to the
secondary of the class 2 transformer 120 VAC 60 Hz IN / 16.5 VAC, 40 VA OUT.
