●This device and its packing is NOT litter and may NOT be disposed of with domestic waste. Please return
this device and its packing to an appropriate recycling point at the end of its service life.
●Please read this user manual carefully and completely before installation and use. Please take into
consideration all warnings mentioned in this manual.
●AT961 is suitable only for permanent panel type mounting
●Installation and use of this device must be done by qualified, authorized and trained technical personnel only.
●Inspect device carefully before installation. Do not install and use broken and defective devices.
●Do not disassemble device. Do not make any repair on any part of the device. There is no accessible part
inside the device. Please contact to manufacturer for broken and defective devices.
●Do not use device in environments subject to flammable, explosive and corrosive gases and/or substances.
●This device is designed for applications only in light industrial environments. This device is not suitable for
medical and residential use. This device is not suitable for use related with human health and safety. This
device is not suitable for automotive, military and marine use.
●Do not allow children and unauthorized people to use this device.
●Before installation and any technical work, disconnect the power supply and mains connections.
●Check the power supply voltage level before power on, and make sure voltage level is in specified limits.
Check quality of neutral line. Improper neutral line may give permanent damage to the device.
●Connect an external power switch and an external fuse (1A, 250VAC) to the power supply line that are easily
accessible for rapid intervention. Connect an external fuse (2A, 250VAC) for each relay output separately.
●Use appropriate cables for power supply and mains connections. Apply safety regulations during installation.
●Install the device in a well ventilated place. Install the device permanently into a proper panel cut-out. Fix the
device with two fasteners supplied with the device. Only front panel must be accessible after installation is
completed.
●Do not operate the device other then the environmental conditions given in Technical Specification.
●Do not operate the device in environments that may cause conductive pollution.
●Take precautions against negative environmental conditions like humidity, vibration, pollution and high/low
temperature during installation.
●Use correct compensation cables for T/C sensors. Connect T/C cable directly to the device connectors.
●Keep device, signal cables and communication cables away from circuit breakers, power cables and
devices/cables emitting electrical noise. Use shielded and twisted signal and communication cables and
connect shield to earth ground on device side. Keep length of signal and communication cables less than 3m.
●In your applications, always use separate and independent mechanical and/or electromechanical
devices/apparatus to support AT961 to handle emergency cases..
●Use insulated cable end-sleeves at the end of cables screwed to the device connector terminals.
●Maximum torque for screwing; 0.5 N.m.
●Please check www.gemo.com.tr for latest device and documentation updates regularly. All updates and all
information are subject to change without notice.
