ABB RET670 Installation And Commissioning Manual

Section 5 Installing the IED
About this chapter
This chapter describes how to install the IED.
5.1
Overview
The mechanical and electrical environmental conditions at the installation site must
be within the limits described in the IED technical data. Dusty, damp places, places
susceptible to rapid temperature variations, powerful vibrations and shocks, surge
voltages of high amplitude and fast rise time, strong induced magnetic fields or
similar extreme conditions should be avoided.
Sufficient space must be available in front of and at the rear of the IED to allow
access for maintenance and future modifications. Flush mounted IEDs should be
mounted so that IED modules can be added and replaced without excessive
dismantling.
