NOTE
●
The control input terminals are not insulated
from the AC power supply. Any equipment
(programmable controller, relay and/or switch)
that will be connected to the control input
terminals must have the contact ratings of
18 VDC and 1 mA min. Provide reinforced
insulation for the parts directly contacted by
human operators.
