WIRING DIAGRAM
CAUTION: DO NOT MATE UNIT CONNECTOR UNTIL INSTALLATION IS COMPLETE AND
AC POWER IS SUPPLIED.
1. The LEM-INV-036-U-V1 requires an unswitched AC power supply of 120-277 volt, 50/60Hz.
2. Refer to the wiring diagrams below. Make connections in the following order ①②③④⑤⑥⑦
3. Consult the factory for other wiring diagrams.

OPERATION/TESTING/MAINTENANCE
OPERATION
When AC power is applied, the LED test switch is illuminated, indicating that the batteries are being charged.
When AC power fails, the LEM-INV-036-U-V1 automatically switches to emergency power, operating the
lighting load at approximately 30% of rated luminaire power (max. 120W) using Power Share Technology. The
LEM-INV-036-U-V1 can also be used as a stand-alone 36 W inverter when used with lighting loads less than or
equal to 36 watts. During power failure, the LED test switch indicator will be off. When power is restored, the
LEM-INV-036-U-V1 switches back to normal mode of operation and resumes battery charging. The minimum
emergency operating time is 90 minutes. The charging time for a full discharge is 24 hours.
TESTING AND MAINTENANCE
The following Periodic testing is recommended to ensure the system is working correctly.
1. Visually inspect the LED test switch (LTS) monthly. It should be illuminated when AC power is applied.
2. Conduct a 30-second discharge test by switching off the emergency breaker every month. The LTS will be
off during test.
3. Conduct a 90-minute discharge test once per year. The LTS will be off during test.
AUTO TEST
The LEM-INV-036-U-V1 has an Auto Test feature which saves cost by reducing the need for manual testing.
1. Initial Auto Test
When the system is connected properly and powered on, the LEM-INV-036-U-V1 will perform an initial
Auto Test. If any abnormal conditions exist, the LTS will flash rapidly*. Once the abnormal condition is
corrected, the LTS will function correctly.
2. Monthly Auto Test
The LEM-INV-036-U-V1 will conduct the first Monthly Auto Test after 24 hours and up to 7 days after initial
power on. Then monthly tests will be performed every 30 days, and will test transfer function from normal
to emergency, emergency function, charging and discharging conditions. Monthly test time is
approximately 30 seconds.
3. Annual Auto Test
Annual Auto Test will occur every 52 weeks after the initial 24 hours full charge, and will test proper initial
battery voltage, 90-minute emergency operation, and acceptable battery voltage at the end of the full
90-minute test.
*If the Auto Test is interrupted by a power failure, a full 90-minute Auto Test will occur again 24 hours after
the power is restored. If the power failure causes the battery to fully discharge, the product will restart the
Initial Auto Test, Monthly and Annual Auto Test.
MANUAL TEST
- Press the LTS 1 time to force a one-second emergency test.
- Press the LTS 2 times continuously within 5 seconds to force a 30-second monthly test. After the test is
complete, the next (30-day) monthly test will count from this date.
- Press the LTS 3 times continuously within 5 seconds to force a 90-minute annual test. After the test is
completed, the next (52-week) annual test will count from this date.
- During any manual test, press and hold the LTS for greater than 3 seconds to terminate a manual test. The
Preprogrammed Scheduled Auto Test time will not change.

OPERATION/TESTING/MAINTENANCE
LED TEST SWITCH (LTS) CONDITION*
- Slow Flash (once per 2 seconds): Normal Charging
- On: Battery Fully Charged - Normal Condition
- Off: Power Failure
- Gradual Change: In Testing Mode
- Rapid Flash (once per second): Abnormal Condition - Corrective Action Required
POWER SHARE TECHNOLOGY
The LEM-INV-036-U-V1 utilizes circuit design which enables sharing of power to allow single or multiple 0-10
Vdc controlled luminaires (up to 120 W combined normal luminaire power) to automatically adjust and share
up to 36 W of emergency AC power. During normal operation, the emergency inverter will pass through normal
dimming voltage (0-10Vdc) on the dim output leads and then supply 3 VDC during emergency operation to
achieve approximately 30% luminaire power during an emergency power failure.
Example: 3- 40W LED luminaires (120W) will share 12 Watts each of the 36 W emergency power per luminaire.
40W X 0.3 = 12 W; the maximum available emergency power is 36 W, therefore; 3- 40W luminaires are
acceptable. If the luminaire power is over 40 W, then 2 or less luminaires can be operated.
When non-dimmable loads are used, the normal and emergency output will be limited to a max. of 36W at
operating temperatures range of 10°C Ta  55°C and 27W between 0°C Ta  55°C.
