5.3. Terminal Configuration

■ <Warning - Turn off power before connecting power terminal>
■ Loosen 5 terminal fixing screws located at top part of detached terminal block CN6 (VIS, +, mA, -, ETH) Connector by
turning counter-clockwise using a Θ driver. Connect DC 18~24 V power to +, and - then connect signal cable to mA.
Tighten 5 terminal fixing screws clockwise (cw) so that terminal does not leave the track then insert Main PCB as the
same condition before disassembly.
