■ How to Install

NOTE

(1) To install the product, select a location where:

• no one may accidentally touch the terminals,

• mechanical vibrations are minimal,

• corrosive gas is minimal,

• Ambient temperature: 0 to 50°C; Ambient humidity: 50 to 90%RH
And the fluctuation is minimal,

• no direct radiant heat is present,

• no magnetic disturbances are caused,

• no wind blows against the terminal board (reference junction compensation ele­ment),

• no water is splashed,

• no flammable materials are around,

(2) Make sure to connect the grounding.
(3) Turn off the product before installation and wiring.
(4) Use the power supply within specifications.
(5) Observe the following instructions for correct installation:

Recommended panel thickness is 1 to 10mm.
Install the product horizontally .
Install the product using attached fixture from the backside of the product.
Turn the screw only up to 180° after the screw touches the mounting panel to prevent
the case deformation by tightening the screw excessively .

(6) Observe the following instructions for correct wiring:

Terminal connection screw is M3.5. Use the crimp-on terminals applicable to M3.5
screw for wiring.
Applicable wire size for input signal and power supply is 1.25mm

6: 440V/5A (Note 3) F: 277V (480V/√3) /5A (Note 4)

(Note 1) Input specs. of 1-phase 3-wire system can only select rated input 3 and 4. Input voltage is 200V AC (100V+100V).
(Note 2) Rated input 1, 2 (1 10V) can also be used at 120V input.
(Note 3) Rated input 5, 6 (440V) is the specs. only for 1-phase 2-wire system and 3-phase 3-wire system.
(Note 4) Rated input A to F is the specs. for only 3-phase 4-wire system. Rated input voltage indicates phase voltage.

A, B: 64V , C, D: 127V, E,F: 227V indicate 110V/√3, 220V/√3, 480V/√3 respectively. In case of 440V/√3 input, it can
be used at E, F: 227V of rated input.

(Note 5) Specify this option when the previous style UZ005(S2.0) with option “Current 2 measuring Function” is required.

Current measuring object of current 2 measuring function:

1-phase 3-wire system : I2current r.m.s. value
3-phase 3-wire and 3-phase 4-wire system : I3 current r.m.s. value

NOTE

Before using the product, check that its model and suffix codes as you ordered.
