6. ID plate and marking data
All actuators have
marking and are destined for use in the
European Union without further requirements.
The
marking on the product, packaging and indications
for use provided with the product indicate ‘presumed
conformity to the directives’ issued by the European
Community.
The manufacturer holds the technical archive with
documentation providing that products have been
examined and evaluated for conformity to directives.
ID plate data are indicated on a polyethylene
adhesive
label applied externally on the outside of the container,
printed in black on a grey background. Values conform to EC requirements in force.
See figure for example of labelling.
7. Electrical power supply
The
KATO 253
actuator is commercially available in two versions identified
according to electrical specifications:
1.
KATO 253 230V~ (a.c.)
: runs on grid tension of 110/230V~ (a.c.), 50/60Hz
(±10%), with a three wire cable
(

.
2.
KATO 253 24V

.
24V═ low voltage actuators can be powered using a station with emergency battery
or approved Class II power supply unit
(double safety insulation)
with an output
voltage of 24V═
(-15% ÷ +25%, ie. min. 20,4V, max. 30V)
.

Selection of power cable section
For 24V
═ (dc) power supply cable section must be checked and calculated according
to cable length. The following table indicates maximum cable lengths for connection
to motors.
