Installation
3.4.2 Electrical Hardware Requirements
Braided shielded, twisted pair, instrument quality wire or cable should be used to minimize the
possibility of noise interference and contact with other voltages. Selection of shielded cable must
comply with local requirements.
Conduit, in addition to braided shielded wire, may also be needed in areas where large amounts
of electrical noise is expected. All cable shields should be terminated to earth ground at one end
only.
The TG5000’s (RED) power connector terminals can accommodate up to 14 AWG (2.08 mm2).
Four conductors are also required for the TG5000 remote junction boxes.
Incoming power and signal cables should be a braided shield cable such as Alpha Wire 3248 or
equivalent. The braided shield must be terminated to the instrument housing with a 360 degree
connection to earth ground or alternatively, the earth ground at the user’s power source location.
An external Class 2 power supply is required to supply 24 VDC +/- 10% to the TG5000. Incoming
power and signal cables should be a braided shield cable such as Alpha Wire 3248 or equivalent.
