Perform all electrical installations in accordance with all applicable local electrical

codes, such as: NPFA 70 (NEC); and ANSI requirements.

WARNING: Incorrect installation and/or operation can cause serious injury or death

to personnel and damage to equipment and/or property. Only qualified personnel are

authorized to install and/or maintain a SolPad device.

WARNING: Use insulated tools to reduce the risk of electrical shock or accidental

short circuits. Remove all jewelry, such as rings, watches, bracelets, etc., when

installing or performing maintenance on the SolPad platform.

WARNING: An electric shock or fire can be fatal to personnel. Inadequately sized

wiring and/or overcurrent protection can cause serious injury or death to personnel

and damage to equipment and/or property.

WARNING: Inadequate grounding methods/conductors can cause serious injury or

death to personnel and damage to equipment and/or property. The grounding

system/conductors must be installed per NEC or CEC requirements.

WARNING: Before servicing a SolPad Load Controller system or replacing any part

of a system you must de-energize the system by flipping the units dedicated circuit

breaker to the off position.

CAUTION: Do not mount or install a SolPad component where is it subject to

physical damage from the surrounding area.

Info: SolPad may choose to revoke any and all warranty of a SolPad system if

visible physical damage due to mishandling, improper installation, or electrical arcing

1. Special Section: Connecting Loads

1.1 About this section

This ‘Connecting’ section is located at the front of the guide to serve as an easy-to-find

reference offering examples for certain use cases. Before beginning a SolPad Load

Controller installation you must read the entire guide and carefully follow each step.

THESE CONNECTIONS EXAMPLES ARE NOT TO BE CONSIDERED AS DETAILED WIRING

DIAGRAMS. ANY INSTALLATION WITH A SOLPAD LOAD CONTROLLER MUST BE COMPLETED

IN ACCORDANCE WITH ALL APPLICABLE LOCAL ELECTRICAL CODES BY A

LICENSED ELECTRICIAN.

1.2 Connection Examples

20A / 120V Circuit Connection

To control a typical 120v circuit in a residence, you’ll

interrupt the line conductor at the breaker and land

it on the relay in the load controller.

 In the electric panel, interrupt the load’s L1

conductor and run it to the normally closed

(N.C.) contact on the 20-amp relay.

 Run a second conductor from the relay’s

COM terminal back to the circuit breaker.

See 20-amp SPDT Relay information in section 2.6

Water Heater Connection (30A / 240V)

Water heaters are often low priority items for

control and among the first to shed. For each

water heater, disconnect one leg from the circuit

breaker.

 In the electric panel, interrupt either the

L1 or L2 conductor and run it to the

normally closed (N.C.) contact on the 30A

relay.

 Run another conductor from the relay’s

COM terminal back to the circuit breaker.

See 30 Amp DPDT Relay information in section 2.

Clothes Dryer Connection (30A / 240V)

Disconnect the leg which supplies the heating

element ONLY, so the motor and controls are still

allowed to run. Determine the correct leg through

trial and error. Disconnect one leg from the circuit

breaker, and then test the dryer. If you the motor

and controls work but there is no heat, the correct

leg has been disconnected.

Some heaters have 220V motors which are trickier,

but if eliminate the heat, you have disconnected

the correct leg.

 In the electric panel, interrupt L1 or L2

(whichever is the heating element leg) and

run it to the normally closed (N.C.) contact

on the 30A relay.

 Run another conductor from the relay’s COM terminal back to the circuit breaker.

See 30 Amp DPDT Relay information in section 2.6

Pool or Spa HEATER (30A / 240V)

As with Clothes Dryers, you want to disconnect the

leg suppling the heating element ONLY. Determine

which leg is which is through trial and error.

Disconnect one leg from the circuit breaker, and

then test the heater. If you the motor and controls

work but there is no heat, the correct leg has been

disconnected.

 In the electric panel, interrupt L1 or L2

(whichever is the heating element leg) and

run it to the normally closed (N.C.) contact

on the 30A relay.

 Run another conductor from the relay’s

COM terminal back to the circuit breaker.

NOTE: Advise the customer once wiring is complete that reprogramming of their Pool or

Spa timer may be required, and to take into account the “On-Peak” periods when doing so.

See 30 Amp DPDT Relay information in section 2.6

Pool or Spa PUMP (30A / 240V)

As with Clothes Dryers, you want to disconnect

the supply leg which breaks the pump ONLY.

Determine the proper leg to control by trial and

error. Disconnect one leg from the circuit

breaker, and then test the pump. If you the

controls work but there is no pumping, the

correct leg has been disconnected.

 In the electric panel, interrupt L1 or L2

(whichever is the pumping element leg)

and run it to the normally closed (N.C.)

contact on the 30A relay.

 Run another conductor from the relay’s

COM terminal back to the circuit

breaker.

NOTE: Advise the customer once wiring is complete that reprogramming of their Pool or

Spa timer may be required, and to take into account the “On-Peak” periods when doing so.

See 30 Amp DPDT Relay information in section 2.6

HVAC – Air Handler (20A / 120V)

Air Conditioners and Air Handlers are normally

high priority items for control, and typically the

last or next to last to shed. In this configuration

the Line between the unit and the breaker is

interrupted.

 In the electric panel, interrupt the load’s

L1 conductor and run it to the normally

closed (N.C.) contact on the 20-amp

relay.

 Run a second conductor from the relay’s

COM contact back to the terminal on

the circuit breaker.

See 20-amp SPDT Relay information in section 2.6

HVAC – Control via low voltage; A/C Compressor and Fan are

controlled

Air Conditioners can be controlled through their

low voltage thermostat wires. In this

configuration you’ll interrupt the red conductor

running from the thermostat to the unit’s

internal transformer.

 The red (R) conductor from the

thermostat needs to be disconnected

from the air-handler transformer’s 24v

terminal. Run this conductor instead to

the normally closed (N.C.) contact on

the 20-amp relay.

 Run another conductor from the relay’s

COM terminal to the 24v terminal on

the air-handler’s transformer.

See 20-amp SPDT Relay information in section 2.6

HVAC Connection – A/C and Heat Control via low voltage – Fan is not

controlled

For this configuration you’ll interrupt the white

(W) and yellow (Y) conductors that run from the

thermostat to the air handling unit.

For the W conductor to control heat:

 Run the W conductor from the

thermostat to the normally closed (NC)

terminal on a 20-amp relay.

 Run a second conductor from the relay’s

COM terminal to the heat terminal on the

air handler unit.

For the Y conductor to control cool:

 Run the Y conductor from the thermostat

to the normally closed (NC) terminal on a second 20-amp relay.

 Run a second conductor from the relay’s COM terminal to the heat terminal on the

air handler unit.

NOTE: this takes 2ea 20-amp relays. See 20-amp SPDT Relay information in section 2.6

Electric Kitchen Range controlled with 50-amp breaker

For this configuration you’ll interrupt

both L1 and L2.

The 50-amp relay terminals are located

on the yellow terminal block.

 Interrupt L1 and L2 coming from

the range, and land them on their

respective ‘NC’ terminals on the

50-amp relay block.

 Then run new L1 and L2

conductors from their respective

‘C’ terminals back the two-pole

breaker in the panel.
