Recommendations for Wiring Your RTB
We recommend that you follow these guidelines when wiring your RTB.
1. Begin wiring the RTB at the bottom terminals and move up.
2. Use a tie to secure the wires in the strain relief (bottom) area of the RTB.
3. Order and use an extended-depth housing (catalog number 1756-TBE)
for applications that require heavy gauge wiring.
See Appendix D for cable considerations.
Wire Terminations
The following sections provide details about wiring terminations to specific
products.
