13.1 Current-carrying capacity of
the regulator
A maximum network current consumed
by the regulator along with its
peripherals cannot exceed 6A. It does
not include heater current which is
supplied with integrated relay, nor a
current consumed by alarm module
supplied by another integrated relay. The
regulator was designed to cooperate with
heaters of power lower than 1.5KW (8A).
Total consumed current also does not
include a current consumed by two
motors of upper and lower feeder
supplied by two voltage contactors inside
the enclosure.
13.2 Connecting HV and LV cables
HV cables for controlled devices are
introduced inside the device through
glands and connected with appropriate
screw terminals. Cables should be
connected
in accordance with
information on plates fixed next to
terminals. Tighten gland nuts and pull
the cable in order to make sure that it
does not come out. Cables with
dangerous voltages can be led only
through appropriate glands. They cannot
be led directly net to each other. It is
forbidden to mix cables with dangerous
voltages 230/400V~ with LV cables (e.g.
from sensors).
Wires of connected cables have to be
protected against delamination with the
use of insulated collets in accordance
with the following figure (a – proper
protection with a collet, b – improper
protection).
