S ANDARDS AND PROVISIONS: Standards, recommendations,
regulations and provisions of the country in which the devices will
operate, must be considered while planning and setting up electrical
devices. Work on 100 .. 240 V AC network is allowed for authorized
personnel only.
DANGER WARNINGS: Devices or modules must be protected from
moisture, dirt and damage during transport, storing and operation.
WARRAN Y CONDI IONS: For all modules LONGO LPC-2 – if no
modifications are performed upon and are correctly connected by
authorized personnel – in consideration of maximum allowed
connecting power, warranty of 24 months is valid from the date of
sale to the end buyer, but not more than 36 months after delivery
from Smarteh. In case of claims within warranty time, which are based
on material malfunctions the producer offers free replacement. he
method of return of malfunctioned module, together with description,
can be arranged with our authorized representative. Warranty does
not include damage due to transport or because of unconsidered
corresponding regulations of the country, where the module is
installed.
his device must be connected properly by the provided connection
scheme in this manual. Misconnections may result in device damage,
fire or personal injury.
Hazardous voltage in the device can cause electric shock and may
result in personal injury or death.
NEVER SERVICE HIS PRODUC YOURSELF!
his device must not be installed in the systems critical for life (e.g.
medical devices, aircrafts, etc.).
If the device is used in a manner not specified by the manufacturer,
the degree of protection provided by the equipment may be impaired.
Waste electrical and electronic equipment (WEEE) must be collected
separately!
LONGO LPC-2 complies to the following standards:
•EMC: EN 61000-6-3:2007 + A1:2011, EN 61000-6-1:2007, EN 61000-
3-2:2006 + A1:2009 + A2: 2009, EN 61000-3-3:2013

4.2 Mounting instructions
Figure 3: Housing dimensions
Dimensions in milimeters.
All connections, module attachments and assembling must be done
while module is not connected to the main power supply.
Mounting instructions:
1. Switch OFF main power supply.
2. Mount LPC-2.VV1 module to the provided place inside an electrical panel (DIN EN50022-35
rail mounting).
3. Mount other LPC-2 modules (if required). Mount each module to the DIN rail first, then
attach modules together through K1 and K2 connectors.
4. Connect delta pressure pipes and actuator wires according to the connection scheme in
Figure 2.
5. Switch ON main power supply.
6. Green LED should turn on according to the able 5.
Dismount in reverse order. For mounting/dismounting modules to/from DIN rail a free space of at
least one module must be left on the DIN rail.
NO E: LPC-2 main module should be powered separately from other electrical appliance connected
to LPC-2 system. Signal wires must be installed separately from power and high voltage wires in
accordance with general industry electrical installation standard.
