Fig. 14 On-rail-mounted regulator.
1– DIN TS35 rail, 2 – catches.
For safety reasons, assure the safe distance
between live parts of working module
terminals and conductive (metallic) elements
of housing (min.10mm) is kept.
Connecting wires should be protected from
tearing and loosening or so arranged that
stress transfer to wire connections with
regulator terminals is prevented.

13.6 IP rating
The housing of working module of the
regulator provides various IP ratings, subject
to the manner of assembly. Explanations -
see Fig. 16a. Upon assembly carried out in
accordance with this drawing, IP20 rating is
provided at the front side of working module
housing (this rating is specified on the rating
plate). The housing has IP 00 rating at the
side of connecting terminals, therefore, the
terminals of working module have to be
isolated and access to this section of the
housing must be prevented.
To get access to the terminals, disconnect
power supply, make sure terminals and wires
are free of mains voltage and remove the
housing of working module.
13.7 Electric connection
Regulator is suitable to work with power
supply of 230VAC, 50Hz. Power supply
features:
3-wires (with protective wires),
compliant with applicable regulations
Note: Upon switching-off the
regulator using keyboard,
hazardous voltage may be present
on its terminals. Before
commencement of assembly
works, disconnect external power
supply and make sure terminals
and wires are free of hazardous
voltage.
Connecting wires should not contact surfaces
temperature of which exceeds their rated
operating temperature.
Terminals no.1-15 of each module are
designed to connect equipment supplied with
230VAC.
Terminals 16–31 are intended to connect LV
equipment (supply voltage below 12V).
Connection of external power
supply of 230VAC to terminals
16-31 or to data transmission
interface RS485 will cause
damage to the regulator and
create risk of electric shock!
