Wiring and cable connections
The pickoff input signal connections are made at terminal strip connection TB2 for
Channel A, and TB3 for Channel B. Power supply and output signal connections are made
at terminal strip TB1. Refer to Table 2-7, Table 2-8, Table 2-9 and Table 2-10.
Important
• For single channel wiring use multi-conductor control and instrumentation cable
(18AWG), or equivalent.
• Earth ground shield at one end only.
• Insulate the shield at the other end.
• For dual channel wiring use multi-conductor control and instrumentation cable
(18AWG), or equivalent.
• Connect both shields to earth ground at one end of the cables and insulate the shields
at the other end.
• The LME housing should be at earth ground.
