What you need to know before installing your
PEC Plus
Before installing your PEC Plus, you need to do some initial preparation:
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 your PEC Plus, which may cause your PEC Plus to fail.
Because it is not possible to completely protect this product internally from the
effects of power surges and other transients, we 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 Appendix D: Installation worksheet on page 84, list all the equipment you want to control
using this PEC Plus. Install the equipment and make your electrical connections according to the
sheet.
3. Using Appendix E: Configuration worksheets on page 86, decide which relays and variable
stages you want to use for each piece of equipment, and how you want the equipment
configured. You can connect more than one piece of equipment to a single relay or stage as long
as the total current draw does not exceed the relay or stage’s limit. For more information, read
Electrical ratings on page 10.
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).
