EMKO Elektronik warrants that the equipment delivered is free from defects in material and

workmanship. This warranty is provided for a period of two years. The warranty period starts from

the delivery date. This warranty is in force if duty and responsibilities which are determined in

warranty document and instruction manual performs by the customer completely.

Repairs should only be performed by trained and specialized personnel. Cut power to the device

before accessing internal parts.Do not clean the case with hydrocarbon-based solvents (Petrol,

Trichlorethylene etc.). Use of these solvents can reduce the mechanical reliability of the device.

Use a cloth dampened in ethyl alcohol or water to clean the external plastic case.

2.3PanelMounting

1-Before mounting the device in your

panel, make sure that the cut-out is of

the right size.

2-Insert the device through the cut-out.

If the mounting clamps are on the unit,

put out them before inserting the unit to

the panel.

2.4InstallationFixingClamp

The unit is designed for panel mounting.

1-Insert the unit in the panel cut-out from

the front side.

2- Insert the mounting clamps to the

holes that located left and right sides of

the device and make the unit completely

immobile within the panel

2.5RemovingfromthePanel

Loosen the screws

1-Pull mounting clamps from left and

right fixing sockets.

2-Pull the unit through the front side of

the panel

Montage of the unit to a system must be

done with it’s own fixing clamps. Do not

do the montage of the device with

inappropriate fixing clamps. Be sure

that device will not fall while doing the

montage.

3. ElectricalWiringDiagram

3.1SupplyVoltageInputConnectionoftheDevice

Make sure that the power supply voltage is same indicated on the instrument. Switch on the power supply

only after that all the electrical connection have been completed. Supply voltage range must be determined

in order. While installing the unit, supply voltage range must be controlled and appropriate supply voltage

must be applied to the unit. Controlling prevents damages in unit and system and possible accidents as a

result of incorrect supply voltage.

There is no power supply switch or fuse on the device. So a power supply switch and a fuse must be added

to the supply voltage input. Power supply switch and fuse must be put to a place where user can reach

easily. Power supply switch must be two poled for seperating phase and neutral. On/Off condition of power

supply switch is very important in electrical connection. On/Off condition of power supply switch must be

signed for preventing the wrong connection.

External fuse must be on phase connection in supply input.

External fuse must be on (+) line connection in supply input.
