ABB CP-C MM Instrucciones De Instalación página 5

(GB) Mounting:
The messaging module is plugged and fixed as shown in Fig. II onto the front side of the CP-C power supply.
Doing so, the pre-cut front foil of the power supply is penetrated by the latching hooks and the plug contacts.
The module must not be plugged in or removed when the power is on.
Function:
The messaging module CP-C MM indicates the correct function of the power supply unit via LEDs and energized output
relay. Furthermore the power supply unit can be switched off by closing of a volt-free contact at the "REMOTE OFF" input.
If the supply voltage at the input of the power supply falls below 82 V AC (70 V DC), the corresponding output
relay "INPUT OK" (contacts 11-12/14) de-energizes and the LED "INPUT OK" turns off.
If the output voltage "OUTPUT" of the power supply falls below 19,8 V DC, the corresponding output relay
"OUTPUT OK" (contacts 21-22/24) de-energizes and the LED "OUTPUT OK" turns off.
Output voltage monitoring is only possible in decoupled parallel operation.
Terminal assignment:

Function
If the terminals are short-circuited (R < 1 kΩ) e.g. via a
n/o contact, the power supply unit is switched off remotely.
If the resistance R between the terminals is > 5 kΩ,
the power supply unit is switched on.
Attention: Terminal potential = Input voltage
Volt-free (dry/floating) change-over contact
11-14 closed and 11-12 open, if the input voltage of the
power supply unit is > 85 V AC / 90 V DC.
11-12 closed and 11-14 open, if the input voltage of the
power supply unit is < 82 V AC / 70 V DC.
11-14 also closed, if REMOTE OFF.
Volt-free (dry/floating) change-over contact
21-24 closed and 21-22 open, if the output voltage of the
power supply unit is > 20,2 V DC.
21-22 closed and 21-24 open, if the output voltage of the
power supply unit is < 19,8 V DC.
