3. BYPASSING THE MAIN SWITCH (+1B-Q1)

Bypassing of the cabinet´s locking mechanism is only allowed if it is done by properly in-

structed, trained, authorized and qualified personnel in case of malfunction or for maintenance

or calibration tasks.

Changes and/or modifications that enable the cabinet’s locking mechanism to be bypassed

permanently are prohibited.

When the <HGPU> is operated with switching cabinet door locking mechanism bypassed, it

is the system owner’s responsibility to provide the operator with the appropriate personal

protection equipment, based on the owner’s assessment of the risk. It is not permitted to

operate the <HGPU> with the switching cabinet door locking mechanism bypassed without

using the appropriate personal protection equipment.

Danger of electrocution!

If the main switch is switched on, the switching cabinet must not be opened

except in case of a malfunction.

Do not touch any live parts while the switching cabinet door locking mecha-

nism is bypassed!

Work instructions:

Access before operation (main switch in position “OFF”):

1) Open the switch cabinet door by means of a switch cabinet key.

2) Turn the lengthening spindle of the main switch a quarter turn to the right to switch on the

main switch.

3) Close the switch cabinet door so far as possible. A complet closing of the door is not

possible!

4) The <HGPU> is switched on and it is possible to operate, maintaine and calibrate the <HGPU>
