4.2.1. Health and Safety for electrical installation
Read and observe chapter 1.2 Health and Safety.
1. Danger: Electrical hazard. Danger of death or fatal injury from electrical
current. Obey all general and regional installation and safety regulations
relating to work on high voltage installations, as well as regulations
covering correct use of tools and personal protective equipment.
2. Danger: Electrical hazard. Danger of death or fatal injury from electrical
current inside the unit in operation. Before opening the unit, disconnect
mains power.
4.2.2. Property Damage Warnings for electrical installation
1. Attention: It is compulsory to ground (earth) the unit before connecting the
power supply. Grounding bolts are provided on the cabinet to connect the
ground-bonding cable.
2. Attention: If the mains connector of the unit is not easily accessible, a
disconnect device in the mains power circuit must be provided within easy reach.
3. Attention: A connection of the mains supply to a power socket requires the
power socket to be nearby the unit.
4. Attention: Before connecting or disconnecting the mains connector at the unit,
ensure that mains power supply is disconnected.
5. Attention: Make sure that an appropriate circuit breaker acting as a disconnect
device (as required by IEC/EN60950-1) and an overcurrent limiting device are
connected between mains power and the unit.
6. Attention: Incorrectly wired connections can destroy electrical and electronic
components.
7. Notice: To avoid corrosion at the connectors caused by electrochemical
processes, the material of the cable connectors must not cause a higher potential
difference than 0.6 V (see electrochemical contact series).
