Setting up the SG Ready Relay
The following hardware (not included in the box) is required for installa-
tion:
•
Miniature circuit breaker (MCB), B16 rated 16A can be used to pro-
tect the SG Ready Relay
•
Electrical cabling to power the relay (two-wire L/N 1.5 mm²)
•
Electrical cabling to connect the relay dry contacts with the SG
Ready Heat pump interface contacts (4 wires each with 0.75 mm²
diameter)
•
Ethernet cable to connect to home router or Ethernet switch:
IEEE 802.3 CAT 6, twisted pair (UTP)
Installation steps
A ) Location: The relay can be installed in the main panel if space is not
a constraint or can be installed in a separate sub-panel closer to the
location of the heat pump
✓
NOTE: Ethernet cable from home router or Ethernet switch should
be accessible to the location of install of the relay to ensure network
connectivity.
B ) Mounting: The relay is DIN rail mountable.
C ) Electrical connections:
1.
Wire the supply wires coming from the output of the circuit
breaker to input of the relay as shown in the following figure:

WARNING: Make sure the circuit is not energized while working on
the electrical connections. Make sure all upstream breakers are open and
low or zero voltage is verified using a multimeter.
2.
Wire the cabling from the dry contact relays (Rel 1 and Rel 2)
to the SG Ready contacts on the heat pump as shown in the
following figure.
