Outdoor ATS Series ev. 1
Page 4 of 5
CAUTION: THE UNIT MUST BE PLACED IN A WELL - VENTILATED AREA TO PREVENT RISK OF
FIRE DUE TO OVERHEATING. VENTILATION SLOTS MUST NOT BE OBSTRUCTED.
CAUTION: The ATS must be protected by an upstream branch circuit protector, or both the Pri-
mary and the Backup, at 125% o the ATS current rating (the maximum input current rating as
shown on the ATS product label) per the National Electric Code or per local electrical codes i out-
side o the United States.
Power-Up Procedure
1. Perform a visual inspection of the Outdoor ATS unit and verify that it is not physically damaged. Verify that
the equipment label states correct voltage, frequency and amperage of the input & output AC power
sources. Also, verify that the stated output voltage, frequency and amperage are compliant with the input
power requirement of the load equipment to be powered by the ATS.
CAUTION: Turn both switches marked as “Primary Input Breaker” and “Backup Input
breaker” to OFF position.
WARNING: Make sure that both Primary and Backup AC input wires are de-energized.
2. Connect both the Primary and Backup AC input to the Primary and Backup input terminal blocks. Torque
terminations from min. 1.5 Nm to max. 1.8 Nm (min. 13.28 in.-lb to max. 15.93 in.-lb).
CAUTION: Make sure that both Primary and Backup AC input voltages and requencies
match those speci ied on the product label a ixed to the ATS unit. The ATS will only operate
when the input voltage is within speci ication and when the input requency is within ± 5 %
o that speci ied. Both primary and backup must be the same nominal requency.
3. Turn on the Backup AC circuit breaker. Make sure that the audible alarm switch is in the "ENABLE" position.
4. The yellow LED should turn on and the alarm sound must turn ON (red alarm LED must turn ON; green
LED must be OFF).
5. Turn on the Primary AC circuit breaker.
6. The green LED must turn on after several seconds. Yellow LED must turn OFF. The audible alarm (sound)
and red alarm LED must turn OFF.
7. Turn off the Primary AC circuit breaker. The green LED must turn off. The yellow Backup LED must turn ON.
ed alarm LED and alarm (sound) must turn ON.
8. Turn on the Primary AC circuit breaker. After several seconds, ATS must return to normal operating
condition as in step 6.
9. Turn off the Backup AC circuit breaker. The green LED must remain ON and the red alarm LED and alarm
sound must turn on.
10. Turn on the Backup AC circuit breaker. After several seconds, ATS must return to normal operating
condition as in step 6.
TESTING WITH ACTUAL LOAD EQUIPMENT (SUCH AS COMPUTERS, PLC, TELECOM EQUIPMENT, ETC.)
CAUTION: To avoid electric shock or accidents, ensure that both Primary & Backup AC
sources are de-energized be ore making the wire connection to the AC sources.
11. If the above test steps (1) through (10) are performed and the ATS is functioning properly, then actual load
equipment can be connected to the output terminal blocks. Torque terminations from min. 1.5 Nm to max.
1.8 Nm (min. 13.28 in.-lb to max. 15.93 in.-lb).
12. Perform steps 3 through 10 assuring that the load is operating properly.
13. End.
