EMS EnviroStart Installation & Commissioning Manual page 2

Single Phase EnviroStart™ Motor Energy
IMPORTANT WARNING
Failure to read and comply with this manual may result in damage to the EnviroStart
Unit and driven equipment and may render the warranty invalid.
1. Only a competent electrician should carry out the electrical installation.
2. EnviroStart must be earthed with an earthing conductor connected to the
earthing terminal.
3. Before installation check the motor rating plate and Section Two of this manual
to ensure that the EnviroStart is correctly rated for the application.
4. Internal components and areas of the control circuit boards, (except the isolated
I/O terminals), can be at mains potential when the EnviroStart is connected to a
three-phase supply. The voltage is extremely dangerous and may cause death or
severe injury if you come into contact with it.
5. When the EnviroStart is connected to the mains, the output connections U, V and
W should be treated as being live even if the load is not being driven.
6. The control I/O terminals are isolated from mains potential but the relay outputs
may have dangerous voltages present even if the mains are not connected.
7. Do not make any connections when the EnviroStart is connected to live mains.
8. Do not make voltage withstand tests on any part of the EnviroStart without
isolating the unit.
9. Do not touch IC-circuits on the PCB. Certain items are static-sensitive and static
voltage discharge may destroy the components.
10. Make sure no power-factor correction capacitors are connected to the load cable
except in a safe manner. (See body text of this document for details).
11. Make sure the cover is closed before applying mains voltage to the EnviroStart.
12. Updated and current Installation and Commissioning Guides are maintained on
the EMS (European) web site at http://www.EnviroStart.com; always check the
web site for latest issue documents before commencing installation.
