Wrng Procedure
1. Turn OFF the recorder and remove the terminal cover.
2. Connect the input/output signal wires to the terminals.
Philips
screwdriver
Crimp-on lug with
insulation sleeves
3. Replace the terminal cover and fasten it with screws.
The proper torque for tightening the screws is 0.6 N•m.

• Relay Contact Input/Transstor Input Specfcatons
Input signal: • Voltage-free contact: Contact closed at 200 Ω or less and
contact open at 100 kΩ or greater
• Open collector: 0.5 V or less (30 mADC) when turned ON,
leakage current of 0.25 mA or less when turned OFF
Dielectric strength: 500 VDC for one minute between input terminals and the
ground terminal
Note
To reduce noise, use a shielded cable for the wiring of the remote control input terminals.
Connect the shield to the ground terminal of the recorder.
