Lower resistances must use the concept JBM-PI-EP & cannot be
connected in this system
To be able to use the JBS-PI-EP connection system safely, the following
restrictions of power as a function of pipe temperatures & max ambient
apply:
JBS-PI-EP power box / +40°C ambient
XPI-(S-)- 8000 to XPI-(S)-5600
Max allowed wattage W/m
Max pipe temperature °C
XPI-(S)-5150 to XPI-(S)-50
Max allowed wattage W/m
Max pipe temperature °C
JBS-PI-EP power box / +56°C ambient
XPI-(S-)- 8000 to XPI-(S)-50
Max allowed wattage W/m
Max pipe temperature °C
