1.3 Installation

A visual inspection of this product for possible damage occurred during shipment is
recommended before installation. It is your responsibility to ensure that qualified mechanical
and electrical technicians install this product.

If there is danger of serious accident resulting from a failure or defect in this unit, power off the
system and separate the electrical connection of the device from the system.

The unit is normally supplied without a power supply switch or a fuse. Use power switch and fuse
as required.

Be sure to use the rated power supply voltage to protect the unit against damage and to prevent
failure.

Keep the power off until all of the wiring is completed so that electric shock and trouble with the
unit can be prevented.

Never attempt to disassemble, modify or repair this unit. Tampering with the unit may results in
malfunction, electric shock or fire.

Do not use the unit in combustible or explosive gaseous atmospheres.

During putting equipment in hole on the metal panel while mechanical installation some metal
burrs can cause injury on hands, you must be careful.

Montage of the product on a system must be done with it’s fixing clamps. Do not do the montage
of the device with inappropriate fixing clamp. Be sure that device will not fall while doing the
montage.

It is your responsibility if this equipment is used in a manner not specified in this instruction
manual.

1.4 Warranty

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.

1.5 Maintenance

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

Switch on the power supply only after that all the electrical
connections 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.

There is no power supply switch on the device. So a power
supply switch must be added to the supply voltage input.

c

Power switch must be two poled for seperating phase and
neutral, On/Off condition of power supply switch is very
important in electrical connection.

External fuse that on Vpower supply inputs must be on
phase connection.
External fuse that on Zpower supply inputs must be on (+)
connection.
