Figure 56. Connection in screwless spring-loaded terminals
Bare end of connecting wire must not be too long
The insulation of the connecting line must extend as far as the terminal
indentation, i.e. there must be no further bare part of the connecting line
visible above the terminal edge (as shown in figure 56 C). Touching live
parts is dangerous to life. The stripped part of the connecting wire should
be shortened, if necessary.
Only one wire or ferrule per terminal
Only one wire or ferrule with strand(s) may be connected in screwless
spring-loaded terminals. The terminal could otherwise be damaged or the
contact not properly made.
If a connecting wire must be disconnected again for any reason, this is
performed in the reverse sequence:
Figure 57. Releasing connection from spring-loaded terminal
Damage to terminals
Never withdraw connecting wires with the terminal closed, since this could
damage the terminal.
The maximum current of auxiliary outputs:
Mechanical relays 8 A each.
Solid-state relays 100 mA each.
– Max. current all outputs together 200 mA (for base meter and
extension board separately)
– Derating above 25 °C ambient 0.8 mA / °C
Voltage outputs 1 A each.
