2. Caution

2.1 Cautions on installation

Avoid the following places for installation.
• a place where the ambient temperature may reach beyond the range of from 0 to 50°C while in
operation.
• a place where the ambient humidity may reach beyond the range of from 45 to 85% RH while in
operation.
• a place where a change in the ambient temperature is so rapid as to cause condensation.
• a place where corrosive gases (sulfide gas and ammonia gas, in particular) or combustible gases are
emitted.
• a place where the unit is subject directly to vibration or shock.
(Vibration or shock may cause output relay malfunction.)
• a place exposed to water, oil, chemicals, steam and vapor.
(if immersed with water, take the inspection by sales office to avoid an electrical leakage and firing)
• a place where the unit is exposed to dust, salt air, or air containing iron particles.
• a place where the unit is subject to interference with static electricity, magnetism, and noise.
• a place where the unit is exposed to direct sunlight.
• a place where the heat may be accumulated due to the radiation of heat.
2.2 Caution on installation on panel
SY24 – SY48 MODELS
• Insert the mounting bracket (accessory) from the rear side until the main unit is securely fit into the
panel. If there should be a play, tighten two screws lightly until the play is eliminated. (Do not tighten
the screws excessively because the mounting bracket can be removed from the stopper by the force.)

• Attach the supplied fixtures (2 pcs.) to PXR5/9 at the top and the bottom, and fasten them using a
screwdriver. The fastening torque should be approximately 0.15N·m (1.5kg·cm).If the plastic fixture is
fastened at excessive torque, it is split horizontally around the center,thus allowing the torque to be
released. If a split appears around the center, there is no problem with the use of the instrument. (The case
is made of plastic. Therefore, be careful not to fasten them excessively). In the case of PXR9, place the
mounting fixture into the mounting hole at the center of the main body. Fig 3 y Fig 4
