!WARNING
For the MS4800 system to comply with IEC 61496-1 and UL 508, the DC
power supply unit must satisfy all of thefollowing conditions:
•
Must be within the rated power voltage (24 V DC ± 20%)
•
Must have tolerance against the total rated current of devices if it is
connected to multiple devices
•
Must comply with EMC directives (industrial environment)
•
Double or reinforced insulation must be applied between the primary
and secondary circuits
•
Automatic recovery of overcurrent protection characteristics
•
Output holding time must be 20 ms or longer
•
Must satisfy output characteristic requirements for class 2 circuit or
limited voltage current circuit defined by UL508
•
Must comply with laws and regulations, regarding EMC and electrical
equipment safety, of the country or region where the MS4800 system
is used (Ex: In EU, the power supply must comply with the EMC Di-
rective and the Low Voltage Directive.)
!WARNING
Double or reinforced insulation from hazardous voltage must be applied to all
input and output lines. Failure to do so may result in electric shock.
!WARNING
Extension of the cable must be within a specified length. If it isn't, safety func-
tion may not work properly, resulting in danger.

!WARNING
To use the MS4800 system in PSDI mode (Re-initiation of cyclic operation by
the protective equipment), you must configure an appropriate circuit between
the MS4800 system and the machine. For details about PSDI, refer to
IEC61496-1, and other relevant standards and regulations.
!WARNING
Do not try to disassemble, repair, or modify this product. Doing so may cause
the safety functions to stop working properly.
!WARNING
Do not use the MS4800 system in environments where flammable or explo-
sive gases are present. Doing so may result in explosion.
!WARNING
Perform daily and 6-month inspections for the MS4800 system. Otherwise,
the system may fail to work properly, resulting in serious injury.
!WARNING
If the MS4800 system is used in an environment where foreign materials such
as spatter may adhere to the product use a cover to protect the MS4800 sys-
tem or inspect and clean the MS4800 system periodically.
!WARNING
Do not use the MS4800 system in an athmosphere containing oil mist or cor-
rosive gas. Failure to do so may result in damage of the product.
!WARNING
When scrapping the MS4800 system, please make sure to comply with the
waste treatment regulations of the country where the product has been used.
