TM Series Power Supplies

Operating Instructions

1.0

Mains Connection

The design of the unit meets the requirements of safety class I according to EN 61010-1, i.e. all metal parts

accessible from outside and exposed to contact are connected with the protective conductor of the supply

network.

Power is supplied via a mains cable with earthing contact.

1.1 Installing the power supply

The power supply should not be operated close to equipment that develops heat. To protect the power supply

from thermal overload the air vents must not be covered and a free space of about 10 cm should be ensured.

1.2 Switching on

The power supply is switched on using the power switch at the front. The power switch separates the unit

completely from the primary side of the transformer. Refer to para 3.1 and 3.2 for correct mains voltage and

fuse settings.

1.3 EMC

The power supply is interference-free according to EN 50081-1 and EN 50081-2. In order to fulfil the limit

values in line with present standards, it is absolutely necessary that only cables which are in perfect condi-

tion be connected to the unit.

1.4 Inspection and Maintenance

If service is needed, due attention should be paid to the regulations according to VDE 0701. The power sup-

ply should only be repaired by trained personnel.
