Section 1: Introduction

This manual is applicable to the following relays:

7SR158 Voltage and Frequency Relay

The ‘Ordering Option’ Tables summarise the features available in each model

General Safety Precautions

External Resistors

Where external resistors are fitted to relays, these may present a danger of electric shock or burns, if touched.

Front Cover

The front cover provides additional securing of the relay element within the case. The relay cover should be in
place during normal operating conditions.
