There can be a maximum of three standard auxiliary relays installed in the SunTouch Power Center.
Depending on the SunTouch kit, relays may not be included in the kit. Relays must be installed at the site.

relay which is located in the right-side of the Power Center. For more information about SunTouch kits, see
page 38. All SunTouch high voltage double pole relays and are rated at 3HP/30A at 240 VAC (1½ HP/30A at
120 VAC).

A standard relay can be installed in any one of the thee locations provided in the SunTouch Power Center with
the exception of the an optional 2-Speed relay, which can only be installed in the right-side compartment of the
Power Center. Power Center relay locations are shown below.
