2.4.3 Protection against contact with electrical parts
This section only concerns devices and drive components carrying voltages exceeding 50 V. Contact
with parts carrying voltages of more than 50 V can be dangerous for people and may cause electrical
shock. During operation of electrical devices some parts of these devices will inevitably carry
dangerous voltages.
DANGER!
High electrical voltage!
Danger to life, danger due to electrical shock or serious personal injury!
The appropriate DIN, VDE, EN and IEC regulations as well as all national and local safety regulations
and rules for the prevention of accidents apply for the assembly and maintenance of the system. The
plant engineer or the operator is responsible for compliance with these regulations:
Before switching on the device, install the appropriate covers and protections against
accidental contact. Rack-mounted devices must be protected against accidental contact
by means of a housing, for example a switch cabinet. The national regulations for
safety/accident prevention must be complied with!
Always connect the ground conductor of the electrical equipment and devices securely
to the mains supply. Due to the integrated line filter the leakage current exceeds 3.5 mA!
Comply with the minimum copper cross-section for the ground conductor over its entire
length (see for example EN 60800-5-1).
Prior to the initial operation, even for short measuring or testing purposes, always
connect the ground conductor of all electrical devices as per the terminal diagram or
connect it to the the earthing system on site. Otherwise the housing may carry high
voltages which can cause electrical shock.
Do not touch electrical connections of the components when switched on.
Prior to accessing electrical parts carrying voltages exceeding 50 Volts, disconnect the
device from the mains or power supply. Protect it from being switched on again.
For the installation the amount of DC bus voltage must be considered, particularly
regarding insulation and protective measures. Ensure proper grounding, wire
dimensioning and corresponding short-circuit protection.
The device comprises a rapid discharge circuit for the DC bus as per EN 60204-1. In
certain device constellations, however, mostly in the case of parallel connection of
several servo drives in the DC bus or in the case of an unconnected brake resistor, this
rapid discharge may be rendered ineffective. The servo drives can carry voltage until up
to 5 minutes after being switched off (residual capacitor charge).
