Omron OS3101 Manual page 14

The OS3101 is designed to be used with a 24-VDC, negative
(protective) ground electrical system. Do not connect it to a
positive (protective) ground el ectrical system. Connecting the
OS3101 to a positive (protective)

resulting in serious injury.
Do not connect any of the OS3101 lines
than 24 V+20%. Also, do not connect to an AC power
supply. Failure to do so may result in electric shock.
For the OS3101 to comply with IEC 61496-1 and UL 508, the DC
power supply unit should satisfy al l of the following conditions:
Should be within rated power voltage (24 VDC
Should comply with EMC Direct ives (industrial environment)
Double or enhanced insulation should be applied between the
primary and sec ondary circuits.
Automatic recovery of overcurr ent protection characteristics
Output holding time should be 20 ms or longer.
Should satisfy output characteristic requirements for class 2 circuit
or limited voltage current circuit defined by UL508.
Should comply with the EMC, laws, and regulations of the country
or region where the OS3101 is
power supply should comply with the EMC Low Voltage Directive.)
Double or enhanced insulation should be applied between the
OS3101 and hazardous voltage sources (such as 230 VAC) to
protect against electric shock.
The cable extension length should
length. Otherwise, the safety func tions may fail to work properly,
resulting in danger.
When the OS3101 is used in a category 3 safety system, use both
control outputs to build the safety system. Using only one control
output may result in serious injury due to a malfunction in the output
circuit.
The protective area should be co rrectly defined and the parameters
related to the protective area should

the machine to fail to stop before an operator reaches the dangerous
area and may result in serious injury.
Do not allow the following types of light to shine directly on the
OS3101.
Incandescent light
Strobe light
Light from optical sensors using infrared light
