Cat. No. RELAY
INSTALLATION INSTRUCTIONS ENGLISH
PK-A3453-10-00-0A
WARNINGS:
• TO AVOID FIRE, SHOCK OR DEATH: TURN OFF POWER AT CIRCUIT BREAKER OR FUSE AND TEST THAT
THE POWER IS OFF BEFORE WIRING!
• TO AVOID PERSONAL INJURY OR PROPERTY DAMAGE, DO NOT install to control a receptacle, or a load in
excess of the specified rating.
• Always disconnect the power supply from the panel's main board prior to making any connections between relay
boards and the main board. Failure to do so, may result in personal injury, damage to the panel, and void its warranty.
• To be installed and/or used in accordance with electrical codes and regulations.
• Must be installed by electrician or other qualified personnel.
• A disconnect switch or a circuit breaker must be provided and marked as the disconnecting device.
• The use of accessory equipment, not recommended by the manufacturer, may cause an unsafe condition.
CAUTIONS:
• If any emergency circuits are fed or controlled from this panel, they must be located electrically where fed. For
example, from a UPS, generator, or other guaranteed power source during emergency and power outage situations.
• If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment
may be impaired.
• For indoor use only.
• DO NOT mount near gas or electric heaters.
• No user serviceable components. DO NOT attempt to service or repair.
• Use this device WITH COPPER OR COPPER-CLAD WIRE ONLY.
Product Description
H Series' relays are designed to be installed in EZ-MAX H Series panels only. Individual
relays of any type can be placed in any position in the panel. Two pole relays fit in the
same space as one pole relays.
Installing Individual Relay Cards
WARNING: TO AVOID FIRE, SHOCK OR DEATH, turn OFF power at circuit breaker or
fuse and test that the power is off before wiring.
1. Disconnect the low voltage control input plug, which is located at the top of the
main board.
2. Align the relay board in the desired relay position and insert the relay card plug
connector (male) into the socket (female) on the main board.
NOTE: Make sure all of the pins line up, and the connection is tight.
3. Insert and tighten the relay card mounting screw.
NOTE: Do not over tighten the relay card mounting screw with a high-amount of torque
force, as this can loosen the relay card plug connector.

Connecting Lighting Loads
CAUTION: Prior to making any connections to the relay outputs, verify that none of the
loads have shorted. Failure to do so, may result in personal injury, damage to the panel,
and void its warranty.
1. Turn the power OFF.
2. Route the lighting system line and load leads through the high-voltage area of the panel.
3. Connect line and load leads for each lighting load to the output terminals of the
appropriate relay, as delineated in the project plans or panel load schedule. Space is
provided for the circuit identification number to be written adjacent to the terminals on
each relay card.
NOTE: If no panel load schedule exists, use the panel load schedule form supplied in the
clear plastic pocket inside the panel door to record the lighting circuit relay assignments,
while connecting the relay.

Connecting Low Voltage Input
Bring the low-voltage wiring for the contact inputs in through the knockouts in the low-
voltage wiring area. The EZ-MAX H Series relay card includes one input. The input is
software, which you can configure via programming to support momentary switches,
maintained switches (latching), motion sensors, or photocells. The input may be connected
prior to programming. Inputs may be connected to any terminal location, regardless of final
control programming. Connect contact closure input devices to the input terminals using
#18 AWG wire.
NOTE: Use the panel load schedule form, supplied in the clear plastic pocket inside the
panel door, to record the low voltage input types while making connections.
The Low Voltage Control diagrams, shown below, are for use with Leviton low-voltage input
devices ONLY.

What to do if...
A blinking green relay board status LED indicates that communication has not
been properly established for this card.
1. Power down the panel.
2. Remove the relay card. Make sure the connectors on the relay card and on the main board are
not damaged.
3. Reinstall the relay card.
4. Power up the panel, see if the LED light stopped blinking, and verify the relay card can
be seen through the controller.
The relay does not turn ON.
1. If the load was removed, check the continuity of the relay terminal blocks.
a. If the green relay board status LED is ON, make sure there is resistance.
b. If the green relay board status LED is OFF, make sure there is no resistance.
2. Verify the supply breaker is ON and energized.
3. The relay contact may be damaged.
The relay does not turn OFF the load.
1. If the load was removed, check the continuity of the relay terminal blocks.
a. If the green relay board status LED is ON, make sure there is resistance.
b. If the green relay board status LED is OFF, make sure there is no resistance.
2. Relay contact may have been welded shut.
3. Circuit from supply breaker may be wired in parallel to load.
