1. Warnings and Safety Hints<br />
1.1 Warnings<br />
During operation, electrical equipment carries dangerous<br />
voltages. In addition, circuit breaker emits hot, ionized<br />
gases when switching currents, especially short circuit<br />
currents.<br />
Installing, commissioning, maintaining, changing or refitting<br />
of this equipment must be carried out only by qualified<br />
and suitably trained personnel and under strict observation<br />
of national and international applicable safety<br />
regulations.<br />
During their operation, circuit breakers must be equipped<br />
with appropriately fitted covers, e.g. in suitable enclosures<br />
or panel boards. Safety distances must be preserved.<br />
Suitably trained service personnel shall only carry out certain<br />
works.<br />
Non-compliance with these warnings may result in death,<br />
and/or severe physical damage and extensive damage to<br />
equipment.<br />
Prior to carrying out maintenance, inspection or checks,<br />
the circuit breaker must be open, the both terminals must<br />
be grounded, the circuit breaker must be switched off and<br />
the control plugs removed.<br />
During breakers’ operation, manually activation of the<br />
breaker is forbidden. Manual activation must only be used<br />
for maintenance and inspection purposes, when breaker<br />
is power off and grounded.<br />
The circuit breaker consists of high energy moving components.<br />
Do not touch the circuit breaker while it is being<br />
switched ON (closing) or OFF (opening). There is a high risk<br />
of major injury.<br />
The control circuits may be equipped with capacitors<br />
bank, which may be charged with dangerous voltages.<br />
Work on this section must be carried out carefully.<br />
