INSTALLATION INSTRUCTIONS FOR HEAD UNIT

These installation instructions are used for installing a Modulus head unit:

WARNING: Please read the “important safety instructions” prior to installation of this product. The mounting instructions can be found inside the mounting kits or downloaded from https://peerlesslighting.acuitybrands.com/Renna

Typical Modulus Installation

Modulus is a Class 1, low-voltage DC power and control distribution system for linear lighting. A single “head unit” takes in AC power and controls, then provides lowvoltage DC power out to one or more connected luminaires that contain DC-DC drivers. Power and control runs in a 4-wire bus that can be connected through fixtures, so up to 32ft of fixture can be powered and controlled by a single drop. DC-DC drivers are digitally addressed on the internal Modulus control bus, so up to 16 zones can be configured on a single run without changing any wiring (see table in Section B for available zones per control type).

Number of fixtures that can be powered by a single head unit is a function of lumen package and desired control zones. See luminaire spec sheet for table of feet per head unit and see Section B of this document for number of zones available for each control type.
Fixture zoning is done by digitally addressing drivers in the fixture – for example, “GA1” in the nomenclature means the drivers are factory-programmed to the first zone. Care should be taken when installing to place fixtures in the correct zone according to job drawings. Zone #s restart at each new head unit. Field-rezoning by the installer is only possible for NLIGHT, NLT, and DALI control types.
Fixtures on separate head units should not be connected – this is prevented by an FK/L or FK/R fixture having a harness connector that’s incompatible with the right (or left) end harness on a standard Renna fixture.

²Uses factory-installed, internal single-channel rIO with external antenna
³ Internal EcoSystem to 0-10V interface
Requires user-installed external rPP20D (x2 for TUWH or two zones) with 0-10V wiring into a standard ZT-type head unit. Order fixtures and rPP20D separately

Head Unit Wiring

A Must connect to luminaires for all input control types! Modulus control lines are polarity-insensitive. Use 12AWG solid wire in grounded conduit for remote placement of head unit up to 50ft away from fixture canopy.
B Line voltage should match ordered voltage option (120/277/MVOLT or 347V). See Section E. for emergency power input wiring diagrams. Separate the luminaire disconnect before servicing. Luminaire disconnects may not be present on units build before Fall 2021.
C Purple/gray will control direct lights, first zone or intensity, blue/blue- white will control indirect light, second zone, or CCT (for tunable white).
Cap blue/blue-white if second channel is unused
D DALI lines are polarity insensitive. Customer to supply DALI power supply external to head unit
E Connect Cat5 to integral nIO on outside wall of head unit
F Screw external antenna onto coax connector on outside wall of head unit after installation
G EcoSystem lines are polarity-insensitive.
H For Chicago Plenum (CP) applications, a cat5 splitter is located inside the Modulus outputs connection area. Installer should pull the splitter through the access plate opening, make cat5 connections, then push the connector back into the wiring compartment before replacing access plates. All connections should be made through the gasketed side access plates for CP head units – do not remove the top cover, which is factory sealed with aluminum tape. Replace tape if removed.

*Older versions of fixture cord have Black, White, Purple, and Gray conductors while Head Unit wires are Orange, Orange, Red, and Black. Connect according to detail on right

Emergency Options

Modulus systems provide emergency functionality by using a feature of the luminaire’s DC drivers that sends the output level to a preset value when power is lost on the Modulus control bus. Head units are wired so that control power is interrupted when normal power is lost. ALL fixtures powered by an emergency head unit remain powered up when normal power is lost, but fixture outputs go to 100%, 0% or some other value when normal power is lost depending on each fixture’s emergency type. See the examples in this section for standard behavior of the two emergency options (EC and ExxINV).

Emergency Option: EC

Use EC emergency type when a central backup power source is available in the building. EC requires an always-on emergency circuit fed by an upstream emergency panel with a UL1008 emergency transfer switch. You can specify 1-6 emergency sections per head unit (or “all on EC” with the WEC option) – these are 4ft sections that will go to 100% when normal power is lost while all other sections on that head unit will go to 0%. This enables traditional emergency lighting designs where individual, spaced-out sections provide egress lighting at 100% while most fixtures are off during loss of normal power.
E.1.2 – EC Normal and Emergency Behavior

Since there’s only one power supply in the head unit to power both EC and non-EC sections in the same run, ALL fixtures will draw power from the emergency circuit during normal power operation. Consult the Modulus Emergency Guide on Modulus fixture webpages to calculate the normal power and emergency power consumption for your fixture run length, lumen package, and emergency type.
E.1.3 – EC Maximum Luminaire Mounting Height
Max. mounting height: 26.3 ft
*Based on 1foot-candle testing on a single RNNAD U4 500LMF 27K at 100% output during loss of normal power. Consult Acuity Technical Sales group for guidance on other scenarios.
E.2 – Emergency Option: E35INV and E50INV
Use ExxINV (either E35INV or E50INV) for a simplified approach to emergency lighting design. ExxINV head units come with a field-installed micro-inverter, and fixtures are programmed to go to 10% of their nominal output on loss of normal power to ensure the inverter load remains below its power limit to provide backup power for at least 90 minutes. If ExxINV luminaires in the space provide at least 10FC at full brightness, 1FC will be maintained in the space during the loss of normal power, meeting the requirements specified in typical emergency egress codes. Order either E35INV (which ships with an Iota IIS-35-HE 35W micro-inverter) or E50INV (which ships with the IIS-50-I 50W micro-inverter). E35INV is suitable for short runs or for use in California. E50INV can power nearly the same length of run per head unit as standard non- emergency fixtures but is not compliant with California Title 20. Consult individual luminaire spec sheets for the maximum run length of fixtures per head unit for each option. Field wiring is slightly different for each option – see Wiring Compartment Detail sections below.
E.2.1 – ExxINV System Diagram

Ships with ExxINV head unit for field installation. Includes 3ft whip but can be installed up to 250ft away with Class 1 wires run through additional conduit (not included) in accordance with local code

Ensure that Inverter Output Voltage Selector Switch always set to 277VAC Out (the left-most switch position) before connecting normal power, regardless of normal power voltage.
E.2.2 – ExxINV Normal and Emergency Behavior

Max. mounting height: 7.6 ft**
Based on 1foot-candle testing on a single RNNAD U4 500LMF 27K at 10% output during loss of normal power, however If ExxINV luminaires in the space provide minimum 10FC at full brightness, 1FC will be maintained in the space during the loss of normal power.
