10. Wiring
Warning
Turn the power supplied to the instrument OFF before wiring or checking.
Working or touching the terminal with the power switched ON may result in an Electric
Shock which could cause severe injury or death.
Caution
• Do not drop wire chips into SCZ10 when wiring, because they could cause fire, malfunction and trouble
• Insert the connecting cable into the designated connector securely to prevent malfunction, or it
may cause malfunction due to imperfect contact.
• Connect the AC power wiring to the designated terminal as is written in this Instruction manual, or
it may burn and damage SCZ10.
• Tighten the terminal screw with the specified torque,
• Use thermocouple and compensating lead wire that fit sensor input specification of this unit.
• Use 3-wire RTD that fits sensor input specification of this unit.
• Do not
confuse the polarity when using DC voltage and current input in the case 24Vdc is used.
• Keep input wire (Thermocouple, RTD) away from power source and load wire when wiring.
• To prevent the unit from harmful effects of the unexpected level noise, it is recommended that a
surge absorber to be installed between the electromagnetic switch coils.
• This unit has neither built-in power switch nor fuse. Therfore it is necessary to install them in the circuit
near the external unit.
(Recommended fuse: Rated voltage 250Vac-Rated current: 2A-Fuse type: Time-lag fuse)
