Connect the Signal Cables for External Synchronization
 DANGER |
|---|
|
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Check for absence of voltage for all three signal terminals
on the external synchronization board 0P4809. When the external synchronization
cables are installed, the terminals on the external synchronization
board 0P4809 may be energized. Disconnect the fuse disconnector device
at the source before removing the transparent protection cover.
Failure to follow these instructions will result in death or serious injury.

Cable Size and Fuse Disconnector Device for External Synchronization
| Fuse and disconnector at source | Fuse disconnector marking | Cable size | Conduits | |
|---|---|---|---|---|
| IEC | In = 2A, I.R=65 kAiC | Fuse disconnector identification number and external synchronization UPS number. | 2 x 1.5 mm2 | – |
| UL/NEC | 2 x 16 AWG | 0.5 inch |
The maximum voltage for external synchronization is equal to the input voltage range given in the specifications. The non-Class 2/non-SELV cables for external synchronization shall be a jacket cable and rated for 600 VAC.
- Remove the transparent protection cover from the external synchronization board 0P4809. The external synchronization board 0P4809 is located on the rear of the front plate.
- Connect the cables for external synchronization
to the external synchronization board 0P4809 and to terminals J8309
and J8310. See cable routing on the illustration. Connect the external
synchronization per your configuration according to one of the diagrams
below. Ensure that fuse disconnector devices are installed at the
source as shown in the diagrams.

- Reinstall the transparent protection cover on the external
synchronization board 0P4809 after signal cabling is completed. DANGERHazard of electric shock, explosion, or arc flashThe transparent protection cover must be installed over the external synchronization board 0P4809.Failure to follow these instructions will result in death or serious injury.
- Mark the transparent protection cover with the external synchronization fuse disconnector identification number.
