removable terminal block: +Vs: Power input +10 to +30V GND : Ground and F.G. :
F.G. stands for Frame Ground (protective ground). It is optional. If you use this pin, it can

value or it may have negative and positive power leads.
When wiring the power supply to the unit be sure to put the power supply negative
ground lead to the middle slot/hole and the positive lead to the +Vs – if the your power
supply has no ground lead but only + and – put the – to the ground/ middle slot/hole and
the + to the +Vs. Don't let the F.G hole/slot confuse you – it's for Frame grounding

If your unit will be subject to lighting or power surges you can wire the FG to the
building power ground to help reduce burn outs.
