DocumentDocumentPELICAN PEARL VDC Expansion Module Model: PEM-VDC Installation Guide DANGER HAZARD OF ELECTRIC SHOCK Disconnect electrical power to the power source and/or the HVAC equipment before installing and wiring the Pelican Expansion Module. Failure to follow this warning could cause electrical shock, peronsal injury, or damage to the controller(s). Before you start The PEARL Expansion Module is designed to work with the Pelican PEARL and a Pelican TC Thermostat ONLY. To configure Pelican devices, a Pelican Gateway must be installed and connected to an active Ethernet port. The Pelican devices will communicate with the Pelican Gateway over a wireless mesh network. Configurations are accomplished through the Pelican ConnectTM web-app. Pearl Economizer Controller PELICAN Pearl Expansion Modulate PELICAN PEM-VDC PEARL TC Thermostat Disconnect Power This device is designed to be installed on 24 VAC systems only. Turn power Off to the equipment either at the circuit breaker panel or by turning off the master power. Installation to be by a licensed professional only. IMPORTANT AVOID CONNECTING POWER TO ANY INPUTS OR OUTPUTS NOT SPECIFICALLY DESIGNED FOR POWER. WIRING POWER TO THE (T1), (T2), (T3), (A1), (A2), (A3), (A4), (S1), or (S2) INPUTS CAN DAMAGE THE CONTROLLERS. TAKE EXTREME CAUTION WHEN WIRING POWER TO THE PEARL AND THE PEARL EXPANSION MODULE. Power off your equipment either at the circuit breaker panel or by turning off the master power. ON OFF 2 Install the Pearl Expansion Modulate Align the expansion module with the opening in the PEARL. Gently slide the module upwards towards the PEARL's three pin connector. Confirm all the pins are inserted into each of the expansion module's terminals and then tighten the (R), (C), and (D) terminals on the expansion module. Pearl Economizer Controller PELICAN DC R Tighten terminals. Pearl Expansion Modulate 3 Installing the PEARL When installing the PEARL these items should be considered: 1) Mount in a location where it can easily control the equipment it will be wired to. This is traditionally a low voltage control cavity at the HVAC equipment. 2) Make sure all the required temperature probes and modulating signals can easily be wired to where the PEARL is mounted. 3) Verify that at least three (3) wires can be used between where the PEARL is installed and where its Pelican thermostat is mounted. 4) There is available 24 VAC power. IMPORTANT THE PEARL IS NOT WATER-PROOF. MOUNT THE PEARL IN A LOCATION WHERE MOISTURE WILL NOT CONTACT OR BUILD-UP ON THE PEARL. Use the best two of the six mounting holes on the PEARL's sub-base to mount it to a flat surface. Use the included 3/16" sheet metal screws. Pelican PEARL Pearl Economizer Controller Control Board Use sheet metal screws to secure the PEARL. PELICAN Pearl Expansion Modulate 4 Wire the PEARL to its Thermostat Connecting a PEARL to its Pelican thermostat requires at least three (3) wires between the two devices. This accommodates a maximum wire distance of 500 feet between the PEARL and the thermostat. Use existing or a new three (3) wire run from the PEARL to where the thermostat is installed. Connect the (R), (C), and (D) terminals from the PEARL to the matching (R), (C), and (D) terminals at the thermostat's back plate. Pearl Economizer Controller 1 PELICAN PELICAN 2 Pearl Expansion Modulate Pelican PEARL Installed at the equipment. 1. Do not insert multiple wires into any Pelican terminals.

PELICAN 3. 4. 6 For detailed HVAC equipment wiring guides, reference the Pelican thermostat and PEARL installation manuals. 1 Wire to a 24 VAC class 2 power circuit only. Total power draw of 175 mA. Pelican Thermostat Backplate Optional: Limited Wiring Installation For installations with limited wires between the PEARL and its Pelican thermostat. You can use the thermostat's included Limited Wiring Module to achieve a three (3) wire installation. Step 1: Remove the Wiring Module from the Pelican thermostat's back plate. Loosen the (R), (C), and (D) terminals on the Limited Wiring Module. Gently slide the module upwards (away from the three pin connector) to remove. Wiring Module PELICAN Loosen terminals. Pelican Thermostat Backplate Step 2: Install the Wiring Module next to the PEARL. Install the Wiring Module on a flat surface near the PEARL. Use 18g PELICAN thermostat wire and wire nuts to connect the (R), (C), and (D) terminals between the wiring module and the PEARL. Tighten the (R), (C), and (D) terminals on the wiring module and PEARL. Pearl Economizer Controller 1 1. Do not wire multiple wires into D C R A3 any Pelican terminals.

For detailed equipment wiring guides, reference the Pelican thermostat and PEARL installation manuals. 4. Wire to a 24 VAC class 2 power circuit only. Total 1 power draw of 175 mA. Pelican Thermostat Backplate Installed inside the building. 8 Wire to Power The PEARL, expansion module, wiring module and the Pelican thermostat must be powered by a common 24 VAC Class 2 power source. Disconnect electrical power to the power source before wiring anything to the PEARL or its thermostat. Failure to follow this warning could cause electrical shock, peronsal injury, or damage to the controller. If you use a separate control power transformer, it is essential that either the auxiliary transformer and the terminal at each control point are in-phase OR isolation relays must be installed between the PEARL and thermostat's 24 VAC outputs and any inputs at the equipment/device being controlled. You must verify this prior to connecting the auxiliary transformer to the PEARL and Pelican thermostat. IMPORTANT AVOID CONNECTING POWER TO ANY INPUTS OR OUTPUTS NOT SPECIFICALLY DESIGNED FOR POWER. WIRING POWER TO THE (T1), (T2), (T3), (A1), (A2), (A3), (A4), (S1), or (S2) INPUTS CAN DAMAGE THE CONTROLLERS. TAKE EXTREME CAUTION WHEN WIRING POWER TO THE PEARL.
