1. Warning
1.1 Installation and wiring
• This controller designed to be installed at the following conditions.
Operating temperature
Operating humidity
Installation category
Pollution degree
• 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.
Voltage used or generated
by any assemblies
Up to 50Vrms or Vdc
Up to 100Vrms or Vdc
Up to 150Vrms or Vdc
Up to 300Vrms or Vdc
Above 300Vrms or Vdc
• 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 satisfies your requirements before installation.
Mains (Power source)
Control output1 (relay output)
Control output2 (relay output)
Alarm outout (AL1)
Alarm outout (AL2)
Alarm outout (AL3) or
