fix the wire,and then connect it to the device.
⚫ The antenna needs to be led out of the device to prevent signal shielding.
三、Multiple Work Modes
◆ Load Wiring
The diverse load situation corresponds to different wiring ways. In addition, if
the immersion heater doesn’t have a temperature sensor, and the GroBoost
needs to use the temperature sensors (Pt1000). The following table 3-1 shows
the wiring diagram of a diverse load situation.The following figure is the overall
detailed wiring diagram.

a singlephase
load
The power input line is for phase L1 input
terminals, loads are for phase L1 output
terminals, PT 1000 is for the T1 terminal, which
is linked with the load in the phase L1

Two
singlephase
loads
Three-phase power line input, and two
single-phase loads are connected separately to
phase L1/L2 output terminals. Phase L1 is
linked with the PT1000 of the T1 terminal,
Phase L2 is linked with the PT1000 of the T2
terminal

Three
singephase
loads
Three-phase power line input, and three
single-phase loads are connected separately to
phase L1/L2/L3 output terminals. Phase
L1/L2/L3 is linked with the PT1000 of the
T1/T2/T3 terminal
