● Overload protection with a power
threshold setting.
● Electrical system overcurrent protec-
tion.
● Power supply indicator.
● Power overload indicator.
● Stepless trip-off delay setting.
● Wide power load control range.
● Resilient to transient power loads
above the set power threshold.
● Single-module enclosure.
● For installation on a DIN rail.
The PMM-02 power limiter auto-
matically isolates supply voltage from the
controlled power loads when they over-
load the set power threshold. The power
threshold can be set smoothly from 0.1
to 3 kW with a potentiometer. The power
threshold trip-on delay of the relay can be
set smoothly from 10 to 90 s.

The device is designed for a
single-phase installation and
must be installed in accord-
ance with standards valid in a
particular country. Installation,
connection and control should be carried
out by a qualied electrician staff, who act
in accordance with the instruction manual
and the device functions. In case of cas-
ing dismantling, the guarantee is lost and
an electric shock may occur. Before instal-
lation make sure the connection cables
are not under voltage. The cruciform head
screwdriver 3,5 mm should be used to in-
stall the device. Improper transport, stor-
age, and use of the device inuence its
wrong functioning. It is not advisable to in-
stall the device in the following cases: if any
device part is missing or the device is dam-
aged or deformed. In case of improper func-
tioning of the device contact the producer.
CAUTION
Do not dispose of this device with
other waste! In order to avoid
harmful effects on the environment
and human health, the used device
should be stored in designated
areas. For this purpose, you can
dispose of household waste free
of charge and in any quantity to
a collection point set up, as well
as to the shop when you buy new
equipment.

MOUNTING, FUNCTIONING
1. Isolate from power the wiring system
to be connected with this product with
its circuit breaker, overcurrent device or
disconnector, as applicable.
2. Use a suitable tester to verify that the
isolated power input wiring is not live.
3. Install the PMM-02 on a DIN Rail in the
respective switchboard.
4. Connect the wiring to the terminals, see
the applicable wiring connection dia-
gram.
5. Turn on the power of the connected wir-
ing system.
6. Set the desired power threshold and
power load trip-off delay.
The control circuit limits the controlled
power load. When the total power load
demand on the controlled power line is be-
low the power threshold setting, the power
loads remain on the rated supply voltage.
When the power load demand exceeds the
power threshold setting, the power load line
is isolated from voltage (powering down the
controlled power loads). The supply voltage
is reapplied to the power loads to test the
power load value when the set trip-on delay
expires. Following this power load test, the
control circuit determines if the supply volt-
age should be reapplied or the power loads
left off. Fine-tune the power threshold after
approximately 40 minutes of operation.

The power limiter can support a staircase lighting timer to form a timer-controlled lamp
power system with a power load limit. Having determined the power load demand in the
control system and with the power limiter’s power threshold set, the system prevents con-
nection and operation of illegal power loads with the control system. Hence, if there is a
power overload which exceeds the power threshold, the power limiter isolates the supply
voltage from the controlled power line and periodically retest the power demand for com-
pliance with the power threshold setting.
The PMM-02 is a model from the PMX range
of power limiters.
