8.0 Operation
This section describes checks to be made before starting the UPS, how to start the UPS, manual battery test, manual
bypass, shutting down the UPS, and disconnecting the utility power from the UPS.
NOTE:
The S4KC’s battery is fully charged before delivery, but some charge will be lost during storage and shipping. To
ensure that the battery has adequate reserve power to protect the connected load, charge the battery for 3 hours before
putting the UPS into service.
8.1 Startup Checklist for the S4KC
Before starting the UPS, perform these checks:
1.
Check that the input/output cables and loads are connected properly and reliably.
2.
Check that all of the battery cables are connected properly.
3.
Check that the communication cables are connected properly.
8.2 Initial Startup & Electrical Checks
1.
Verify that the input/output circuit breakers are off.
2.
During initial system checks, disconnect all loads.
3.
inspect all wiring, cables, and connections.
4.
if external battery cabinets are used, verify that the battery cables are fully inserted in the sockets.
5.
Place the manual bypass breaker in the BYPASS position.
6.
Turn on the branch circuit disconnect to apply voltage to the input terminal block.
7.
Using a voltmeter, verify the expected L1–n–L2 voltage. (refer to “12.0 Specifications”.) Verify that the same voltages
are measured at the output terminals. The Bypass LED (by the switch) will illuminate.
8.
After verifying proper input voltage to the UPS terminal block, turn off the branch circuit power, close all access
panels to the distribution box and reapply input power.
9.
Close the input circuit breaker located on the distribution box. The green Ac input LED should illuminate on the
front panel.
10.
Press the On button for 4 seconds. After several seconds, the UPS On LED will illuminate continuously. if the batteries
are determined to be charged above 80%, an automatic battery test will run for about 15 seconds.
11.
Close the output circuit breaker on the rear of the power distribution box. The light by the input breaker will illuminate.
12.
return the breaker to the inVErTEr position. The output terminal block will be powered at this time.
13.
Connect all loads for normal operation.
