Line Voltage Power Connections
Mount the panel enclosure –Mount the EZ-MAX H panel securely to the building structure in accordance with local code requirements
- Remove the panel door prior to mounting the enclosure. All mounting holes are located such that no additional disassembly is required to complete mounting.
- Mounting keyhole location and dimensions are included in the EZ-MAX H Panel Installation Instructions
Install individual relay cards as required –Panels are shipped empty without relays installed, relays must be field installed
- Control power must be disconnected to the panel main board prior to installing relay cards
- Once installation of all cards is complete, restore control power to main board
- Read and follow the installation instructions provided with the individual relay cards when installing
Connect controlled lighting loads –Each relay card is provided with terminal blocks for connection to lighting circuits to be controlled
- Each terminal will accommodate two (2)-#10-#14 copper solid or stranded wire of the same size and type
- Relays connected to the same supply circuit may be jumpered on the line side
- All line voltage connections should be made with the circuit breaker feeding the load in the locked off position
Test controlled lighting loads –Once circuits are connected to line and load sides of terminals, test each for shorts and proper grounding prior to energizing the circuit breaker feeding the load
Record controlled lighting loads in panel schedule –After completion of all testing, include in the panel schedule the name and/or location of the load controlled and the panel and circuit designation of the source line power
Panel Components
-
EZ-MAX H Series Interface –The easy to use and understand color LCD Display with keypad has been designed based on input styles of commonly used devices such as cell phones
-
Panel Door Lock –The EZ-MAX Panel is designed to be locked once the qualified electrician has completed all connections. All programming, system status, and manual controls are available via the user interface once the door is secured.
-
Low Voltage Input Device Wiring Diagrams –Indicates point-to-point connection requirements for each type of device
-
Line Voltage Input Leads –These leads are marked for various input supply voltages
-
Control Power Disconnect–A disconnect
plug is provided for low voltage input control power to allow for safe removal and replacement of relay cards -
Individual Relay Card–Relays are individually mounted for easy replacement, improved reliability and to allow for panels to include any mix of relay types
-
Relay Manual Override Button–Allows for relays to be manually operated. Manual control of relays is also available through the User Interface
-
Relay Status Light–Indicates relay operation status
-
Relay Board Input Terminal Block–Any type of low-voltage input including Switches, Motion Sensors or Photocells may be connected to any relay input terminal block. These inputs are software assignable as to type and control. Any input can control any relay or group.
-
Line Voltage Control Circuit Terminals–Lighting circuits are connected to these heavy duty screw terminals. Each terminal will accommodate two #14 – #10 stranded or solid copper wire of the same type and size.
-
Auxiliary Inputs–The EZ-MAX Panel is supplied with additional low voltage inputs to accommodate a wide variety of control scenarios that require more than one input for a relay or group. Any type of low voltage input including Switches, Motion Sensors or Photocells may be connected to any input terminal block. These inputs are software assignable as to type and control. Any input can control any relay or group.
-
Dry Contact Output Terminals–Each Output Terminal allows for the EZ-MAX H Panel to signal other systems with N.O./N.C. momentary or maintained contacts
-
Wireway Divider-Separates Line and Low Voltage wiring
Low Voltage Input/Output Connections
Always use and follow installation instructions
-
Connect Low Voltage Inputs–There are low voltage inputs, one each on each relay card and auxiliary inputs on the main board. Any device can be connected to any input. All inputs are software assignable to any type of device, including low voltage switches, motion sensors, or photocells. Any input can control any relay, group or output. Wiring diagrams for each type of device are indicated inside the panel door and in this document. Each panel provides enough device power for one device per relay, including devices that may be wired in parallel to a single input.
-
Inputs should be connected based on zone control. Where relays are controlled by single devices, inputs should be connected to the input terminal on that specific relay. Even though any input can be mapped to any relay or group, it is easier for programming and future modifications if inputs and relays are aligned.
-
Switches or sensors that control the same zone should be connected in parallel to
a single input. Low voltage switches and motion sensors can be connected in parallel for like devices when more than one device controls the same zone. -
Record Inputs in Panel Schedule After completion of all connections, include in the panel schedule the name, type and/or location of the input device and the relay or group controlled.

WORKING WITH PRIORITIES
The EX-MAX H Series Panel supports an array of four priority levels for Inputs
and Schedules with Master being the highest priority. The most commonly used
are Low and High with Normal being the panel wide default. Think of these as a
vertical array with 4 priority “slots”. Each Relay has its own “priority
array” where each slot can be populated with an ON or OFF state. The current
state of the Relay will always be the state in highest slot. Priorities are
persistent and are continuously evaluated to determine the relay state. For
example, a relay that is scheduled ON by a Schedule at Low priority will not
turn ON after a photocell input with an OFF Priority set at Normal has
previously turned it off. This can be very useful, especially when combining
Photocell and Schedule control where the Schedule is turning outdoor lights ON
near dawn in the morning.
- Slot 1 Master N/A
- Slot 2 High OFF
- Slot 3 Normal ON
- Slot 4 Low N/A
Some inputs can be set to enable Temporary Priority. This creates a priority “one shot” ON or OFF event where the priority is not persistent. A Temporary Priority controls the relay at one of the slot levels but then is immediately is cleared out.
