• To avoid an electric shock, prior to connecting the ST's power
cord confirm that the ST's power supply is completely turned OFF,
via a breaker, or similar unit.
• The ST400-AG41-24V/ST401-AG41-24V/ST402-AG41-24V /
ST403-AG41-24V units are designed to use only DC24V input.
Any other power level can damage both the ST and the power
supply.
• Since there is no power switch on the ST unit, be sure to attach a
breaker-type switch to its power cord.
• When the FG terminal is connected, be sure the cord is grounded.
• If the power cord is pulled strongly, the power plug may fall out.
• When the FG terminal is connected, be sure the wire is grounded.
Not grounding the ST unit will result in excess noise and vibration.
