Thermon TraceNet TCM 18 - Manual (Page 18)

Location of Terminals Torque Values (Typical)*
RTB6 5.3 to 7.0 in. lbs. (0.60 to 0.79 N-m)
PM6 12.5 to 13.5 in. lbs. (1.41 to 1.53 N-m)
Distribution Equipment 13.2 to 15.9 in. lbs. (1.49 to 1.80 N-m)
*Required torque values may vary depending on individual panel designs and size
of terminals. Refer to project documentation for additional information.
Table 1: Recommended Torque Values
TraceNet Panel Wiring
TraceNet TC Series panels are configured and prewired into an integrated heat trace
control and monitoring system. Clean terminal strips are provided to facilitate the
field wiring into the panels. Refer to the project specific panel drawings when in-
stalling the field wiring within the panel. Field wiring is conventionally shown by
dashed lines. All field power wiring materials used shall be suitable for the intended
service and shall be rated for insulation service temperatures up to and exceeding
221
◦ F (105 ◦ C) unless otherwise higher values are noted in project specifications.
All TraceNet components terminal block connections should be tightened using a
torque indicating screw driver to the levels indicated in Table 1.
When a panel is rated for IP54 and/or NEMA-4, entries into panels must meet IP54
and/or NEMA-4 ingress protection levels to maintain the environmental rating of the
panel.
Serial Communication Wiring
TraceNet TC Series panels may be linked together for communications with a RS485
communication cable at distances up to 4000 feet (300 m.). In addition, a termina-
tion module should be used at each end of the RS485 network. The recommended
communication cables for use in the RS485 network are as given in Table 2.
