3. Mounting to the control panel
3.1 Site selection

CautionUse within the following temperature and humidity ranges.
Temperature: 0 to 60 (32 to 140 ), Humidity: 0 to 90%RH (No icing, no condensation)
If the PA-4000 is installed within a control panel, the ambient temperature of the PA-4000 must be kept
to under 60 . Otherwise the life of electronic parts (especially electrolytic capacitors) of the PA-4000 will
be shortened.
Ensure the mounting location corresponds to the following conditions:
A minimum of dust, and an absence of corrosive gases
No flammable, explosive gases
No mechanical vibrations or shocks
No exposure to direct sunlight, an ambient temperature of 0 to 60 (32 to 140 ) that does notchange rapidly
An ambient non-condensing humidity of 0 to 90%RH
No large capacity electromagnetic switches or cables through which large current flows
No water, oil or chemicals or where the vapors of these substances can come into direct contact
with this unit

Be sure to install the power controller with themark on the front face upward. Refer to Section 3.2.
Electric shock might be caused because parts, of which electric potential is the same as that of power
supply or load voltage, are exposed.
Be sure to store the power controller in a case or a control panel.
Control panel inside must be well-ventilated.
Be sure to install the power controller vertically.
When installing plural power controllers, take the space between units into consideration. See (Fig. 3.3-3).
Be sure to use the terminal cover when using this instrument.

Be sure to match the phase of the main circuit with that of power supply.
For the terminal screw diameter, refer fo Section “3.2 External dimensions”.
The rapid fuse and fuse holder (both sold separaterely) are provided.
For the main circuit wiring, use the wiring material as thick as or thicker than those listed in (Table 4-1)

4.2 Connecting various setting circuits
Use twisted wires or shielded wires, and avoid parellel wiring to the power line.
The short-circuiting bar has been used in connecting control signal terminals 2-3. Remove theshort-circuiting bar for unnecessary setting circuits.
Current running through the setting circuit is very small amount of 10mA DC. So use contacts which do
not cause contact failure.
The external setting unit (sold separately, 1k for output setting, 10k for gradient setting) and scale
plate (sold separately) are provided.
By combining Shinko indicating controllers via a simple connection, optimal temperature control can be obtained.
