Specifications

Descriptions

Multi-Page LCD screen that can display the following:

A:

• Power draw and energy usage at each output.
• Firmware, Mac Address, and Regulatory Info.
• UID of the Host that the module is communicating with.
• Real-time Bluetooth status connectivity icon.

B: Manual Load Switches – Toggle to the ON position to switch the load on. Toggle to AUTO for normal operation. Switch A controls output A, Switch B controls output B.

C: PAIR Button – The PAIR button is a multi-use button. The duration that the button is pressed and held determines the function that gets initiated: Press and Release – Cycles through the screens available on the LCD (POWER > ENERGY > INFO 1 > INFO 2). Press and hold – Press and hold for 2 second to put the module into pairing mode. Press and hold for 5 seconds to reset.

D: Input Power Connections – Connect the outputs from two feeder breakers to inputs A and B on the module. See the Wiring section below.

E: Output Power Connections – Connect output A and output B to separate loads. See the Wiring section below.

F: 120V AC Connection – Plugs into the 120V AC bus bar in the breaker panel. The voltage on this connection powers the module.

G: Pigtail Neutral – A neutral wire protrudes from the module’s rear and gets wired to the neutral bar in the breaker panel.

Features

• Control capability for loads up to 2400VA per channel.
• The GPM-H2R20120-21 Dual 20 Amp Relay Module is compatible with Schneider Homeline, Eaton BR, Siemens, and CE Powermark Gold load centers with a one-inch on-center bus bar.
• Dynamic management of loads.
• Built-in energy monitoring; +/- .5% revenue grade accuracy / 1 sec sample time.
• Communicates over the air using Bluetooth Low Energy (BLE) technology.
•  Manual load switches, available on the front panel, can toggle power to the outputs On and Off.
• Color LCD display for easy identification and load status.

Important Information

•  The breaker(s) feeding the module should not be larger than 20 amps.
• Each relay output can switch up to 20 amps.
•  To determine the number of breaker panel spaces needed, add the number of spaces required for the circuit breaker(s) to the number of spaces needed for the module.
  • A single pole circuit breaker requires one space.
  • A 2-pole circuit breaker requires two spaces.
  • Each Companion Module requires two spaces.
• Savant recommends not connecting any mission-critical loads such as medical devices to this relay module.

ELECTRIC SHOCK! The 120V AC, 60 Hz source poses an electrical shock hazard that has the potential to cause serious injury to installers and end users.
CAUTION! Risk of Electric Shock – More than one disconnect switch may be required to de-energize the device before servicing
IMPORTANT! A licensed electrician is required to install any of Savant’s Relay Companion Modules.

NOTE: This wiring requirement was based on the National Electric Code (NEC) (ANSI/NFPA70), Canadian Electric Code, Part 1 (CEC), and local codes Minimum Size of Conductors.

Installation into Breaker Panel

1. Remove power from the breaker panel by switching off the panel’s main breaker.
2. Position and install a circuit breaker into one of the slots in the panel. Press firmly until the breaker is fully seated onto the appropriate bus bars.
3.  Install a second breaker alongside the first.
4. Position and install the Companion Relay Module into the slot where it will be installed. Press firmly until fully seated onto the appropriate bus bars. This module is typically installed alongside the breakers installed in steps 2 and 3 but doesn’t need to be.
5. HELPFUL! A relay module fills two slots in the breaker panel but connects to only one phase (120V AC). See the diagrams below. 5. Refer to the Wiring section below and make the appropriate connections.

Wiring

Use the diagrams below when wiring the modules. The diagrams cover the following scenarios:

Standard Neutral Bus Bar with ARC Fault Breakers
Breaker panel without a plug-on neutral bus bar (with ARC Fault type feeder breakers).

Standard Neutral Bus Bar with Standard Breakers
Breaker panel without a plug-on neutral bus bar and standard type feeder breakers.

Circuit Test Instructions

Use the instructions below to test the relay modules. The setup requires:

• 20 Amp Dual Relay Companion Module.
•  (2) loads (20 amps max for each).
•  (2) 20 amp circuit breakers.
• Breaker test panel.
• 120V AC source

IMPORTANT!

• When making connections, observe all general electrical best practices including local wire sizing guidelines.
• The GPM-H2R20120-21 Companion Module can accept up to a #12 AWG wire. See the Branch Circuit Minimum Size of Conductors table on the previous page for wire sizing information.

1. Plug the two feeder circuit breakers and one 20 Amp Dual Relay Companion Module into the circuit breaker test panel.
2. Connect the output from one of the circuit breakers to Input A on the module.
3. Connect the output from the remaining circuit breaker to Input B on the module.
4. Connect a load to Output A.
5. Connect a second load to Output B.
6.  Connect the unused side of each load to the neutral bus bar in the breaker panel.
7.  Connect the neutral wire on the Companion Module to the neutral bus bar.
8.  Apply power to the breaker panel (not shown in diagram).
9. Toggle the 20 amp feeder breakers to On.
10.  To test, toggle the CIRCUIT POWER switches A and B to ON and verify both loads switch On.
11. Toggle the CIRCUIT POWER switches to AUTO and verify the loads switch Off
