PISA11

PISA11-Series

All terminals are easy to access when mounted on the panel.

Input, outputs and signal terminals are separated from each other to help in error-free wiring.

Instructions:

a) Use appropriate copper cables that are designed for minimum operating temperatures of:

60°C for ambient up to 45°C and minimum

75°C for ambient up to 60°C and minimum

90°C for ambient up to 70°C.

b) Follow national installation codes and installation regulations!

c) Ensure that all strands of a stranded wire enter the terminal connection!

d) Screws of unused terminal compartments should be securely tightened.

e) Ferrules are allowed.

A high voltage drop between the power supply and the protection module might cause a malfunction. It is not

avoid undesired undervoltage conditions on the input of the protection module.

Use an appropriate wire size which matches to the ampacity of the power supply.

One task of the PISA module is the distribution of the current from a large amperage power supply to four current

monitored output channels. This permits wires with smaller cross-sections than would be needed for the ampacity of

the power supply. Therefore, the PISA11 module is equipped with a redundant electronic current measurement and an

additional emergency Mosfet to protect the wires. In case of an overload, all outputs will shutdown.

For the coordination between wire sizes and load currents, the relevant regulations must be observed. In most cases,

these are VDE 0891, VDE 0100-523 and the IEC/EN 60204-1. This means that the following wire sizes shall be used in

typical applications:

1A output:

(approximately equals AWG26)

2A output:

(approximately equals AWG24)

3A output:

(approximately equals AWG22)

4A output:

(approximately equals AWG20)

6A output:

(approximately equals AWG18)

10A output:

(approximately equals AWG16)

12A output:

(approximately equals AWG14)
