⚫Installation

Although there is no restriction in particular on the installing position, the installation place should

be free from dust and moisture so as to prevent insulation failure due to dewing. Due attention

should be paid to the installation environment such as improving ventilation by installing a cooling

fan if temperature rise is expected due to apparatuses around the product. Avoid the installation

at a place subject to continuous vibration because there is the possibility of contact failure

of cable connections.

CAUTION

Never install the product at a humid or moist place. It is dangerous

because electric shock will be caused.

Do not install it at a place where ambient temperature is very high.

Internal circuits may be damaged due to high temperature.

Installation at a place subject to constant vibration may result in contact

failure of cable connections.
