Install the Heater Blanket
Each TR170 VFD kit is supplied with either a one or two heater blanket system that needs to be
installed during VFD replacement. For most applications, the heater blanket installation only
requires replacing one heater blanket, but in some IPak II applications, an additional heater
blanket as well as applicable wiring and accessories may also need to be installed to make heater
blankets operational.
The following two diagrams show installation of heater blankets and their applicable wiring and
accessories in IPak II Low Ambient applications and shows the 460V option.
