Siemens AG ⋅May 1998

The following list is not a complete description of all

safety measures required to operate the device or

module. Special operating conditions may require adĆ

ditional precautions.

Warning

Hazardous voltages are present in this

electrical equipment during operation.

Non-observance of the safety rules can

result in servere personal injury or proĆ

perty damage.

DThe earthing screw of the device

must be connected solidly to the proĆ

tective earth conductor before any

other connection is made.

DHazardous voltages can be present on

all circuits and components conĆ

nected to the supply voltage or to the

measuring and test quantities.

DHazardous voltages can be present in

the device even after disconnection

of the supply voltage (storage capaciĆ

tors!)

DCT circuits must not be operated with

open secondaries.

DThe limit values given in the Technical

data must not be exceeded at all, not

even during testing and commissioĆ

ning.

Dnly qualified personnel shall work on

and around this equipment. For corĆ

rect and safe operation of this device

it is indispensable, that the equipment

is transported correctly, stored, asĆ

sembled and connected properly and

thoroughly operated and maintained.

This instruction manual does not purport to cover all

details in equipment, nor to provide for every possible

contingency to be met in connection with installation,

operation or maintenance.

Should further information be desired or should partiĆ

cular problems arise which are not covered suffiĆ

ciently for the purchaser's purpose, the matter should

be referred to the local Siemens sales office.

Qualified personnel has to be trained for assemĆ

bling, connection, commissioning and operation of the

product and has to have qualifications in conformity

with their responsibility, such as:

DTraining or instruction, respectively authorization to

switch on and off, isolate, connect to earth and

mark current circuits and devices/systems in conĆ

formity with the standards of safety regulations.

DTraining or instruction for utilization and care of

adeduate safety equipment in conformity with the

standards of safety regulations

DTraining for first aid

CE-Conformity

This product is in conformity with the directive of the

Council of the European Communities on the approxiĆ

mation of the laws of the Member States relating to

electromagnetic compatibility (EMC Council Directive

89/336/EEC).

Conformity is provided by tests that have been perforĆ

med according to article 10 of the Council Directive in

accordance with generic standards EN 500B1-2 by

Siemens AG

The device is designed and manufactured for applicaĆ

tion in industrial environment.

The device is designed in accordance with internatioĆ

nal standards of IEC 255 and the German standards

DIN 57435 part 303 (corresponding to VDE 57435

part 303).
