2.3 Connector System of Generator
Warnings
To prevent possible electrical shock, fire, or personal injury:

Do not touch any of the connections to the output terminals when any
voltage is present.

Do not make connections to the output terminals when any voltage is
present. These voltages can be lethal.
Current cables of generator (for max 120A) use plastic
“push – pull” connectors. With these
connectors, user simply plugs them into terminals until a click sound is heard. It means that connector
is locked.
While pulling out these connectors, they should be released first. This is achieved with pressing gently
and then pulling it out completely. With such a gentle push unlocking of internal mechanism happens.
Figure 6
– Current cable connector on the front panel of PTE
Each current phase is equipped with one (mutual) output terminal (red) and two input (black)
terminals. The bigger one is designed for currents up to 120A, the smaller one is designed up to 12A
but with different maximum power output for small currents (see pictures in next chapter).
Voltage and current connectors are compatible with standard laboratory banana types.
2.3.1 Power Characteristics of PTE (Generator)
Figure 7 - Bigger input terminal - Current
Figure 8 - Smaller input terminal - Current
From these characteristics it is obvious that the high current
(“120A~ max”) input is used for direct
meters which usually have lower resistivity on current terminals. On the other hand, low current (
“12A
max.”) input is dedicated for indirect meters which usually come with higher resistivity on current
terminals.
