1. Warning
1.1 Installation and wiring
• This controller designed to be installed at the following conditions.
Operating temperature -10 to
50 [°C]
Conforming to IEC1010-1
Installation category
II
Pollution degree 2
Operating humidity 90%RH or less (Non condensation)
Location Indoor
• The controller must be installed such that with the exception of the connection to the mains,
creepage and clearance distances shown in the table below are maintained between the
temperature probe and any other assemblies which use or generate a voltage shown in the table
below.
Failure to maintain these minimum distances would invalidate the EN 61010 safety approval.
Up to 50Vrms or Vdc
Voltage used or generated
by any assemblies
Clearance

0.2
Up to 150Vrms or Vdc 0.5
Up to 300Vrms or Vdc 1.5
Above 300Vrms or Vdc Contact with our sales office.
Up to 100Vrms or Vdc 0.2

• If the voltage shown above exceeds 50Vdc (i.e. hazardous voltage), the basic insulation is required
between all terminals of this controller and the ground, and supplementary insulation is required for
the alarm output.
Isolation class of this controller is as shown below. Be sure to check that the isolation class of the
controller satises your requirements before installation.
Mains (Power source)
Control output1 (relay output)
Control output2 (relay output)
Alarm output (ALM1)
Alarm output (ALM2)
Measured value input
Internal circuit
Control output1 (SSR drive output / Current output)
Control output2 (SSR drive output / Current output)
Retransmission
Digital input (with Retransmission)
Communication (RS485) circuit
Digital input (DI1, DI2) (without Retransmission)
: Basic insulation,
: Non-insulation,
