Supervision Relay –SR100 - User’s Manual
SECURITY ADVICE 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 a measuring
instrument.
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
Installation and use of devices includes work with dangerous currents and voltages, therefore such work shall be
carried out by qualified persons only. The 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 instrument is used for measuring or protection, please contact a person who is responsible for installation of
such system.

Supervision Relay –SR100 - User’s Manual
BEFORE SWITCHING THE DEVICE ON
Check the following before switching on the device:
nominal voltage,
supply voltage,
nominal frequency,
voltage ratio and phase sequence,
current transformer ratio and terminals integrity,
protection fuse for voltage inputs (recommended maximal external fuse size is 6 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,
integrity of earth terminal,
proper connection and voltage level of I/O modules.
WARNING
A current transformer secondary should be short circuited before connecting the device.
