3.2 How to Install

Installation Conditions

The instrument must be installed in a location where the following conditions are met.

Ambient temperature and humidity

• Ambient temperature: 0 to 50°C

However, in case you mount the AC power supply model subunits DS400/DS600 directly to a

panel, or if you apply the DIN rail, or mount them in a rack, it is possible to use them in a range

of –10 to 60°C.

WARNING

• When the environmental temperature is 50°C or more, the temperature

of the rear panel may rise to more than 70°C. Thus, touching the rear

panel under these circumstances has the danger of sustaining burns.

• To prevent a fire, always use the instrument in a vertical position, and

do not block the upper side of the modules (a space of at least 3cm is

necessary).

• Ambient humidity: 20 to 80%RH for –10 to 40°C, 10 to 50%RH for 40 to 50°C, 5 to 30%RH

for 50 to 60°C (However, no condensation should be present.)

• Installation location: Room

• Installation height: Altitude up to 2,000 m

Note

Internal condensation may occur if the instrument is moved to another place where both the ambient

temperature and humidity are higher, or if the temperature changes rapidly. In case of thermocouple input,

this might result in erroneous measurements. In those cases, allow the instrument to achieve eqailibrium

with to its new environment for at least one hour before starting operation.

Never install the instrument in any of the following locations:

• in direct sunlight or near heat sources

• where an excessive amount of soot, steam, dust or corrosive gases are present

• near strong magnetic field sources

• near high voltage equipment or power lines

• where the level of mechanical vibrations is high

• in an unstable place

Installation Method
