Installation
3.3 Connection of the MBZ300 control panel
The following three connection types exist for the modules:
à
Supply voltage
à
Power module
PM
à
Power module extension
PME
à
Drive module
DM
à
BUS connection (ribbon cable)
à
All the modules (only connection
PME
–
PM
on the module top, remaining modules on the bottom)
à
External components
à
Detectors, drives etc. (plug-in terminals on the module top)
3.3.1 Connection of the supply voltage
The following must be connected (if not already done in the factory):
à
Internal power supply
à
Batteries (also have to be placed in the central housing)
à
Switching power supply units to the power module
PM
and, if necessary, power module extensions
PME
à
Drive modules
DM
to the supply voltage
All the other modules do not require a connection to the supply voltage. The following diagrams show the con-
nection for:
à
1
power module
PM
with
1
switching power supply unit 10 A or 24 A (with MBZ300 N8 max. 8 A)
à
1
power module
PM
with
1
power module extension
PME
and
2
switching power supply units 10 A or 24 A
à
1

PM
with
2
power module extensions
PME
and
3
switching power supply units 10 A or 24 A
The number of drive modules
DM
that can be connected to a switching power supply unit with
PM
or
PME
de-
pends on the maximum current consumption at the respective switching power supply unit.
Application examples:
à
Switching power supply unit 10 A with
1
DM
for max. 10 A current consumption (for MBZ300 N8 max. 8 A)
– or –
Switching power supply unit 10 A with
2
DM
for two ventilator groups with max. 5 A current consumption each
à
Switching power supply unit 24 A for
2 DM
with max. 10 A current consumption each
– or –
Switching power supply unit 24 A for
4
DM
, if the max. current consumption does not exceed 10 A per
DM
and 24 A in total
