• Do not install the unit in direct sunshine.
• Avoid vibration, sudden temperature changes, wind, water, or excessive dirt.
• Operate in environments with temperatures of between -5°C to 40°C and
humidity of between 45% and 85% R.H. (non-condensing).
• Mount the unit on a solid frame or wall.
Installation work
• Do engineering work and wiring in accordance with the requirements by laws
and regulations related to hazardous area devices.
• Only a trained professional with good knowledge of Explosion protected
devices should be allowed to perform the installation work.
Grounding
• To avoid electrical shock and accident from static electricity, plug the power
cable into a properly wired earth grounded receptacle, or ground the "E"
terminal of Power terminals before connecting anything else to any of the
instrument binding posts.
• Do not share grounding with other units that create electrical noise.
Power supply

frequency of 50 or 60 Hz. Use a stable power source free from instantaneous
dropout or noise. Sharing a power line could result in malfunctioning.
