Chapter 2: Installation
What you need to know before installing the Supra
1. Read
Understanding power surges and surge suppression
below.

If you do not install external surge suppression devices, you risk damage to
the electronics inside the Supra, which may cause the Supra to fail.

Because it is not possible to completely protect this product internally from
the effects of power surges and other transients, Phason highly recommend
that you install external surge suppression devices. For specific
recommendations, see your electrical contractor.

If you do not take these precautions, you acknowledge your willingness to
accept the risk of loss or injury.
2.
Using the installation worksheets in
Appendix D
(starting on page 123), list all the equipment you
want to control using this Supra. Install the equipment and make your electrical connections
according to the sheet.
3. Using the configuration worksheets in
Appendix E
(starting on page 125), decide which relays
you want to use for each piece of equipment, and how you want the equipment organized by
zone in the Supra. You can connect more than one piece of equipment to a single relay
as long
as the total amps do not exceed the relay’s limit
. For more information about the control
ratings, see
Supra electrical ratings
on page 20.
Understanding power surges and surge suppression
Power surges can be caused by external influences (outside the barn – for example, lightning or
utility distribution problems) or they can be caused internally (inside the barn – for example, starting
and stopping inductive loads such as motors).
One of the most common causes of power surges is lightning. When lightning strikes the ground, it
produces an enormously powerful electromagnetic field. This field affects nearby power lines, which
transmit a surge to any device connected to it, such as lights, computers, or environmental controls
like the Supra. Lightning does not have to actually strike a power line to transmit a surge.
Surge suppression devices offer some protection from power surges. Because it is not possible to
internally protect this product completely from the effects of power surges and other transients,
Phason highly recommends that you install external surge suppression devices. For specific
recommendations, see your electrical contractor. If you do not take these precautions, you
acknowledge your willingness to accept the risk of loss or injury.
