CONNECTING PANEL POWER

WARNINGS:

  • When power is applied to the transformer, the unused transformer leads become electrified. Cap unused transformer leads with wire nuts to prevent an electrical short.
  • Panel supply power must be de-energized during installation and servicing of the EZ-MAX panel.

The panel is designed to operate on 120,208, 240 or 277V AC input voltage. Panel input power is supplied to the power supply located in the upper-right of the panel, as shown in the image below. The output power to the EZ-MAX main board is in the upper-center channel of the panel.

  1. Turn the power OFF.
  2. Route the dedicated panel power supply leads to the transformer, and connect them to the appropriate system voltage specific leads.
  3. Connect the power supply’s ground lead to the panel chassis’ grounding lug.
    A label indicates that this ground lug is adjacent to the connection’s location.

NOTES:

  • The connections from supply power to the panel’s power supply, is depicted on the input control power supply.
  • If validation of the transformer output is required, the voltage output must be 24V DC, and you can test this from the low-voltage secondary leads connected to the low-voltage control input plug.

CONNECTING LIGHTING LOADS

WARNING: Prior to making any connections to the relay outputs, verify that the loads have not 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 line-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.
    NOTES:

    • There are no neutral connections to EZ-MAX relays.
    • 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 relays.
    • The panel ships with relays installed and electrically connected at their input control sides. However, if relays must be installed, refer to the applicable relay installation instructions, supplied with the individual relay cards.

LEVITON-EZ-MAXTM-H-Series-Lighting-Control-Panel-07

CONNECTING LOW-VOLTAGE INPUTS

Bring the low-voltage wiring for the contact inputs in through the knockouts in the low-voltage wiring area where indicated in the image on the cover page. The typical connections for singular devices are: Wire size #14, 16, 18, 20, or 22 AWG. Tighten the terminal wire screws with 4 in-lb (0.45 N-m) of torque.+

  • Inputs can be programmed to support momentary switches, maintained switches (latching), motion sensors, or photo sensors.
    Each relay card includes one low-voltage input. You can connect the inputs prior to programming.

  • Each main board includes two auxiliary inputs and one output with N.C. and N.O. dry contacts. You can connect the inputs prior to programming.

  • You can connect any input device to any terminal location, regardless of final control programming.

  • Connect contact closure input devices to the input terminals with #18 AWG wire.

  • All relay inputs located on a relay card can control the relay to which they are affixed as a momentary N.O. contact. This is a default setting on the EZ-MAX H Series controller.

  • Auxiliary inputs do not, by default, control anything. You can program the auxiliary inputs via the controller. NOTES:

  • 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.

  • Most input devices can be located up to 500+ feet away from the panel. Exact distances depend on quantity of devices, mixture of devices connected, and the gauge of the wire.

  • It may be necessary to use an auxiliary power supply to power occupancy sensors, as there can be more sensors required than the panel can energize. If this is so, you must use an OPP20 Power Pack, which ensures that the Black (- COMMON) wires between the input, sensors, and power pack are interconnected.

  • The EZ-MAX relay panels can power up to eight input devices, such as occupancy sensors, daylight sensors, and wall stations with pilot lights.

OPERATING PANEL

The user interface control ribbon cable connects between the user interface ribbon cable connector on the main board and the user interface module that is attached to the panel door.
Make sure that the red indicator in the cable aligns with the Pin 1 designation. The green ground jumper connects between the panel door and the panel housing’s ground lug, labeled “GND”.
Provide control power to the panel, and restore power to the lighting circuits at the source circuit breakers.
The panel takes a few moments to initialize, at which time the User Interface (UI) screen on the front of the panel door initiates and displays the clock, date, and time zone (factory default settings).
Inside the panel, the main board’s power status LED shows a continuous green light. The relay board’s status LED turns ON, and stays green for approximately 2 seconds, and then goes OFF.
Push, but do not hold the relay manual control button on each relay card to operate each relay, and to test functionality. The relay state status LED turns ON, and stays red when the relay is energized. The LED turns OFF when the relay is not energized.
The panel is fully functional and ready to control the lighting loads.
