11.5 IP protection rate
Enclosure of the regulator’s executive
module provides various IP protection rates,
depending on the method of installation. Rys
23a
provides and explanation. After
enclosing in accordance with this drawing,
the device has protection rate IP 20 from the
front side of the executive module enclosure
(specified on the rating plate). From the side
of the terminals, the casing has protection
rate IP00, thus the terminals of the executive
module must unconditionally be enclosed, in
order to prevent access to this part of the
casing.
If it is necessary to access the part with the
terminals, disconnect the mains supply,
make sure that there is no voltage on
terminals and leads, and remove the
executive module enclosure.
11.6 Electric connection
Regulator is designed to be fed with 230V~,
50Hz voltage. The electrical system should
be:
three core (with protective wire),
in accordance with applicable regulations.
Caution: After the regulator is
turned off using the keyboard,
dangerous voltage can occur on the
terminals. Before starting any
assembly
works, you must
disconnect the mains supply and
make sure that there is no
dangerous voltage on the terminals
and the leads.
The connection wires should not have contact
with surfaces of temperature exceeding the
nominal temperature of their operation.
Terminals number 1-15 are intended only for
connecting devices with mains supply
230V~.
Terminals 16-31 are intended for cooperation
with low voltage devices (below 12 V).
Connecting mains supply 230V~ to
terminals
16-31 and to
transmission connectors RS485 will
damage the regulator and creates
risk of an electric shock!
Tips of the connected wires, especially power
leads, must be secured against splitting by
means of insulated clamp sleeves.
The feeder cable should be connected to the
terminals marked with an arrow.
All peripherals (such like: pumps,
RE-marked relays and connected
recipients) may be connected only
by qualified persons in accordance
with applicable regulations. Safety
precautions to prevent electrocution
shall be observed.
Regulator shall be equipped with a
set of pins connected to 230V AC
mains.
