Busbar system
Series 8188
7.3.1 Electrical Connection
• Comply with the specifications provided in the "Technical Data" chapter.
• Connect the conductors with particular care.
• The connection line must comply with the relevant regulations and must have the
required cross section. The cross section must be in accordance with the information
on the bushing.
• Ensure that the wiring is short-circuit proof and earthed.
• Ensure that the wiring is earthed and short-circuit proof, or that the conductors have
double insulation, e.g. by
- using doubly insulated conductors
- using a protection hose to provide additional insulation for the conductor
- using additional bar insulation
• Ensure that the maximum permissible conductor temperatures are not exceeded by
selecting suitable conductors for use and a suitable means of running them.
• Ensure that the conductor insulation extends as far as the clamping units.
• Make sure that you do not damage (nick) the conductor when stripping it.
• Ensure that the maximum permissible conductor temperatures and the maximum
permissible surface temperature are not exceeded by selecting suitable conductors for
use and a suitable means of running them.
• Prevent mechanical damage to the conductor insulation caused by rubbing against
sharp-edged or movable metal parts.
• Regardless of the rated operational voltage, connect all uncoated and non-live metal
parts to the protective conductor system.
• Observe the clearance and creepage distances according to IEC/EN 60079
