POINTS OF CAUTION
■ CONFORMITY WITH EC DIRECTIVES
• This equipment is suitable for use in a Pollution Degree 
2 environment and in Installation Category II, with the
maximum operating voltage 300V.
Basic insulation is maintained between the input and output.
Prior to installation, check that the insulation class of this 
unit satisfies the system requirements.
• The equipment must be mounted inside a panel.
• The  equipment  must be installed such that  appropriate 
clearance and creepage distances are maintained to conform
to CE requirements. Failure to observe these requirements
may invalidate the CE conformity.
■ POWER INPUT RATINGS
•  Power  input  ratings  are  specied  by  the  model  number 
suffix code. Check the power input voltage for the unit on
the specification label.
AC power: 100 – 240V AC rating: 85 – 264V, 47 – 63 Hz,
130VA min.
DC power:  24 V DC rating: 24V ±10%, 2,5A min.
■ ENVIRONMENT
• Indoor use
• When  heavy  dust  or  metal  particles  are  present  in  the 
air, install the installation base inside proper housing and
ventilate it.
• Do not install the base where it is subjected to continuous 
vibration.  Do not apply physical impact to the unit.
• Environmental temperature must be within 0 to 55°C or 32 
to 131°F (0 to 50°C or 32 to 122°F for AC power) with relative 
humidity within 30 to 90% RH (30 to 85% RH for AC Power) 
in order to ensure adequate life span and operation.
•  Be  sure  that  the  ventilation  slits  are  not  covered  with 
cables, etc.
■ WIRING
• Do not install cables (power supply, input and output) close 
to noise sources (relay drive cable, high frequency line, etc.).
• Do not bind these cables together with those in which noises 
are present.  Do not install them in the same duct.
■ AND ....
• The unit is designed to function as soon as power is supplied, 
however, a warm up for 10 minutes is required for satisfying
complete performance described in the data sheet.
