Baumüller Nürnberg GmbH 5.94005.12
DANGER
The intermediate circuit carries electrical potential: it is imperative that the
provided cover is used.
BUM 63 / 64:
L1
Mains commutating reactor
BUM 63 / 64:
1C1, 1D1
DC link to further units e.g. ballast
If UL508C has to be observed: Use 60°C / 75° C copper conductors only
(UL508C, Nov 27, 1996, Tab. 39.2).
BUM 62: Nominal tightening torque of the terminal screws: 4 Nm resp. 35,4
pound-inches.
BUM 63, 64: Nominal tightening torque of the terminal screws: 6 Nm resp.
53,1 pound-inches.
BUM 64: Fan
2U1, 2V1, 2W1
Circuit protection according to VDE 0100;
BUM 62 / 63 fan power supply internal
BUM 64 3 x 400 V 50 Hz 0,23 A
3 x 400 V 60 Hz 0,27 A
Netzteil 24 V 24 V power supply with secure isolation (PELV) according DIN 19240 for
supplying the electronic parts
Current consumption: BUM 62 3 A
BUM 63 3,5 A
BUM 64 2,5 A
NOTE
The power supply has capacitors at its input (250 µF); which means, on
switching the 24 V supply, charging currents are present!
At continuous operation below 24 V -10 % (21.6 V) the cooling power of
the internal ventilator is reduced. Power reduction of the mono power unit
on requirement.
