Installation
This document provides the information needed to install
CPO-VAV2A controller. It describes the dimensions, mounting
details and the terminal connections to these devices.
Safety instructions
•
When performing any work (installation, mounting, start-
up), all instructions given by the manufacturer and in
particular the safety instructions provided in this document
are to be observed.
•
The CPO-VAV2A controller must be installed and mounted
only by authorized and trained personnel.
•
If the unit is modified in any way, except by the
manufacturer, all warranties concerning operation and
safety become invalid.
•
Make sure that applicable local standards and regulations
are observed at all times.
•
Use only Honeywell supplied or approved accessories.
•
Before the system is dismantled, disconnect the power
supply by either removing the power terminal block from
the controller, or by means of local isolation. Read the
following caution note carefully.
Caution
Disconnect the power supply before you start to
install the CPO-VAV2A controller. Do not
reconnect the power supply until you have
completed the installation.
