Remarks concerning the operator safety:

1. General

n

 The digital clock is destined to be installed inside or outside buildings.

n

 Non-authorized removal of the required housing, inappropriate use, incorrect installation or opera-

tion create the risk of injury to personnel or damage to equipment. For more detailed information 
please study the user’s manual.

n

 All operations concerning transport, installation, and commissioning as well as maintenance must be 

carried out by qualified, skilled personnel and national regulations for the prevention of accidents 
must be observed.

n

 According to this basic safety information, qualified, skilled personnel are persons who are familiar 

with the installation, assembly, commissioning, and operation of the product and who have qualifi-
cations necessary for their occupation.

2. Transport, storage

Please observe the notes on transport, storage and appropriate handling.
Observe the climatic conditions given in Technical Data.

3. Installation

n

 The DZ digital clock must be installed according to the regulation and instructions given in this user’s 

manual.

n

 Ensure proper handling and avoid mechanical stress.

n

 Do not bend any components and do not change any insulation distances.

n

 Do not touch any electronic components and contacts.

n

 Electronic devices may contain electrostatically sensitive components, which can easily be dama-

ged by inappropriate handling.

n

 Do not damage or destroy any electrical components since this might endanger your health!

4. Electrical connection

n

 Before switching the digital clock on, one must check the correctness of connection to the network.

n

 In case of the protection terminal connection with a separate lead one must remember to connect it 

before the connection of the digital clock to the mains.

n

 When working on live instruments or devices, the applicable national regulations for the prevention 

of accidents must be observed.

n

 The electrical installation must be carried out according to the appropriate regulations (cable cross-

sections, fuses, PE connection). Additional information can be obtained from the user’s manual.

n

 Do not connect the digital clock to the mains via an autotransformer.

n

 The documentation contains information about installation in compliance with EMC (shielding, groun-

ding, filters and cables). These notes must be observed for all CE-marked products.

n

 The manufacturer of the installation or installed auxiliary devices is responsible for the compliance 

with the required limit values demanded by the EMC legislation.

n

 The 

RS-485 socket

 serves only for the connection of digital clocks operating with the MODBUS 

protocol.

5. Operation

n

 Installations including DZ2 or DZ3 digital clocks must be equipped with protection devices accor-

ding to the corresponding standard and regulations for prevention of accidents.

n

 After the digital clock has been disconnected from the supply voltage, live components and power 

connections must not be touched immediately because capacitors can be charged.

n

 The housing must be closed during operation.
