Maintenance

DANGEROUS ELECTRICAL VOLTAGE

All maintenance work must be carried out by skilled electricians in

compliance with the valid safety regulations, the mains voltage and

the maximum current input values of the individual system compo-

nents.

Prior to connecting a thyristor power unit, the following must be

strictly observed:

Power OFF.

Provide a safeguard to prevent unintentional reclosing.

Verify the safe isolation from supply.

Connect to earth and short circuit.

Cover up or safeguard all live parts.

DANGEROUS ELECTRICAL VOLTAGE

Prior to any maintenance work - unless described otherwise - the

system must always be switched off!

In the event of necessary measurement or test procedures at the ac-

tive system, the applicable safety and accident prevention regula-

tions must be strictly observed. In any case, suitable insulated tools

must be used!

Danger of life through inappropriate EMERGENCY-STOP facilities!

EMERGENCY-STOP facilities must be operative in all modes of the

system. Releasing the EMERGENCY-STOP facility must by no means

result in an uncontrolled restart of the system!

Danger of explosion of batteries!

Batteries must not be opened forcefully, recharged, soldered at the

cell body or thrown into fire!

Replace empty batteries with new ones only!

DANGEROUS ELECTRICAL VOLTAGE

The right to perform repair/maintenance work on the thyristor power

unit components is reserved to the BOSCH service department or to

repair/maintenance units authorized by BOSCH!

Only use spare parts/replacement parts approved by BOSCH!

Run-down batteries or accumulators must be disposed of according

to regulations.
