Important Information

The IOTA ILBHI CP 2H HE SD HV is a 2-hour constant power emergency lighting driver designed for LED fixtures. It requires an unswitched AC input of 347-480 VAC. The unit features AC Activate technology, which automatically engages the battery charging circuit upon detecting AC power. It is suitable for damp locations and operates in ambient temperatures between 0°C and 55°C.

Installation

Safety First: Before installing, ensure AC power is off and the Threaded Body Test Switch (TBTS) is disconnected.

Mounting

The unit should be mounted on or near the fixture above the ceiling. The flex conduit must be wired into the driver/lamp compartment or an electrical junction box on the fixture.

Wiring

LED Load and Normal Driver: Refer to the wiring diagram provided in the manual. The unit is designed to interface with high voltage (non-class 2) LED loads.
AC Input: Connect the BLACK wire to the 347/480 Line and the WHITE wire to the Neutral. The case must be grounded.

TBTS Installation

Locate a suitable position for the TBTS visible outside the fixture.
Drill a 1/2" diameter hole in the luminaire wall or wireway cover.
Insert the TBTS and secure it with the TBTS nut.
Connect the TBTS connector to the socket and apply the status indicator sticker.

Operation

Normal Mode: AC power is present. The AC driver operates the LED module, and the emergency driver is in standby charging mode. The TBTS light indicates the battery is charging.

Emergency Mode: Upon AC power failure, the unit automatically switches to emergency mode, illuminating the LED module at reduced output for a minimum of 120 minutes.

Testing and Maintenance

Testing

Automatic Testing: The unit automatically tests the emergency function for 60 seconds monthly and 120 minutes annually.
Manual Testing: Press and hold the TBTS button for two seconds when the status light is GREEN. The test lasts 60 seconds.

Load Calibration

Load calibration is required whenever the connected LED load is changed. It occurs automatically 48 hours after installation or re-initialization. To initiate manually, press and hold the TBTS button for 20 seconds.

Maintenance

To perform maintenance, disconnect AC power and then disconnect the battery circuit by either unplugging the TBTS or pressing and holding the TBTS button for five seconds within the first 30 seconds of emergency mode.

Practical help

Common problems

Emergency LED module does not operate when TBTS button is pressed

Check wiring, ensure LED module is compatible, verify battery has charged for at least one hour, and ensure TBTS is properly inserted.

TBTS charging LED not on

Verify AC power is on and TBTS is properly inserted into the emergency driver socket.

Fixture does not operate in normal mode

Check wiring of the emergency driver and AC driver, and ensure AC power is supplied to the AC driver.

Emergency driver does not operate for at least 120 minutes

Ensure battery is fully charged, LED module is within specifications, or check if the battery is at the end of its life.

Before use

Ensure AC power is turned off before installation.
Ensure the TBTS is disconnected before installation.
Verify the LED load is compatible with the emergency driver.
Ensure the AC power source is unswitched (347-480 VAC).
Allow the unit to charge for at least 1 hour before functional testing.

Specs in practice

Input Voltage: 347-480 VAC (Must be unswitched).
Emergency Duration: Minimum 120 minutes of operation.
Operating Temperature: 0°C to 55°C ambient temperature.
