Power supplies are not provided with fuses, but
they are protected against overloading or short-
circuiting by a heat sensor (thermoprotector),
to restore power, it is necessary to cut OFF the
mains voltage for about one minute. Reconnect
power after having eliminated the problem.
Do not obstruct the openings for ventilation or
heat dissipation to allow the equipment to op-
erate correctly. The power supply can be fixed
on DIN bar or screwed to the wall.
All power supplies can provide power for a
maximum of 6 (24V-3W) lamps for illuminating
push-button panel name plates. If required add
the necessary PRS210 transformers (approx.
1 for 10 lamps).
General technical data
Input voltage:
127Vac or 220-230Vac

Warning
All power supplies in this manual can work
either 127Vac or 220-230Vac.
Check carefully the right connection.
