INSTRUCTION MANUAL

DESCRIPTION

Transformers are used to supply
electronic systems where it is required
to lower voltage value to the appropriate
level. The universal casing enables mo­unting on the TH-35 DIN rail or on the
surface. Available versions of secondary
voltage: 8 V AC, 12 V AC, 24 V AC and

3 V AC, 5 V AC, 8 V AC.

FEATURES

● Electronic systems supply

● used as bells and doorchimes trans-

formers,

● short circuits and overloads resi-

stant,

● inner thermal protection,

● threemodular casing,

● TH-35 DIN rail or surface mounting.

The device is designed
for single-phase installa­tion and must be installed
in accordance with stan­dards valid in a particular

MOUNTING

1. Disconnect the power supply from the

mains by the phase fuse, the circuit­breaker or the switch-disconnector
that are joined to the proper circuit,

2. Check if there is no voltage on con-

nection cables by means of a spe­cial measure equipment,

3. nstall TRM-XXX devices in the switch-

board on TH 35 DIN rail or on the sur­face,

4. Connect the cables with the termi-

nals,

5. Switch on the power supply from the

mains,

6. While surface mounting screw protec-

tion shield,

7. Switch on the voltage.
