Security Advices and Warnings
Please read this chapter carefully and examine the equipment carefully for potential damages which
might arise during transport and to become familiar with it before continue to install, energize and
work with an iHUB-L1.
This chapter deals with important information and warnings that should be considered for safe
installation and handling with a device in order to assure its correct use and continuous operation.
Everyone using the product should become familiar with the contents of chapter »Security Advices
and Warnings«.
If equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
PLEASE NOTE
This booklet contains instructions for installation and use of iHUB-L1. Installation and use
of a device also includes handling with dangerous currents and voltages therefore should
be installed, operated, serviced and maintained by qualified personnel only. ISKRA
Company assumes no responsibility in connection with installation and use of the product.
If there is any doubt regarding installation and use of the system in which the device is
used for measuring or supervision, please contact a person who is responsible for
installation of such system.
Before switching the device ON
Check the following before switching on the device:
Nominal voltage.
Terminals integrity.
Protection fuse for voltage inputs (recommended maximal external fuse size is 10 A).
External switch or circuit breaker must be included in the installation for disconnection of
the devices’ aux. power supply. It must be suitably located and properly marked for
reliable disconnection of the device when needed.
Proper connection and voltage level of I/O module.

Communication gateway iHUB-L1
Description of the device
The iHUB-L1 communication gateway is intended to connect various equipment into
communication network via Wi-Fi communication. The gateway has build-in two optical (IR)
communication ports and the RS485 serial communication with the MODBUS protocol. RS485
communication enables data transmission and thus connection of communication gateway into
the RS485 network and communication with various equipment, which is equipped with RS485
communication (e.g. energy meters, bi-stable switches, power monitoring devices, etc.), via TCP
MODBUS.
The iHUB-L1-IO is also equipped with pulse input and temperature sensor (Pt1000) input.

Figure 1: Appearance of communication gateway iHUB-L1.
A built-in green LED diode indicates different operation states of the iHUB-L1. A tactile switch is
built-in for reset and factory reset of a gateway. Short press resets the gateway, pressing button
for more than 5 seconds (LED diode starts blinking fast) will do a factory reset (meaning setting
iHUB-L1 to factory settings and turn into access point mode). Connecting terminals are built to
be fastened according to EN 60715 standard. The iHUB-L1 interface with corresponding
equipment enables setting and reading the instruments.

iHUB-L1 application
The iHUB-L1 can be used in a variety of applications including:
Single-phase single point metering and control.
Three-phase single point metering and control.
Connecting different devices via IR communication and RS485 communication.
Connecting different devices via Wi-Fi (e.g. Pt1000 temperature sensor).
Monitoring single or multiple devices.
Figure 2: Connection diagram for iHUB-L1. It is connected to an energy meter (on the
left side of the iHUB-L1) and to latching switch (on the right side of the iHUB-L1) by IR
communication. It is possible to read and control data with the computer or mobile
phone.
