2 Power connection

Do not connect mains to the desktop power supply before connecting the power supply to the
router.

Connect the DB9 female connector from the desktop power supply to the main unit. Tighten the screws to
assure a proper contact. To connect mains to the desktop power supply you need a mains cord with IEC
320 connector.
The BES-0808CP/75 is normally delivered with the desktop power model AC ±5V / 10W. Upon
customer request, BES-0808CP/75 can also be delivered with DC ±5V / 30W, which may be fed by a 36
– 72 VDC mains power source. A Frame mounted power supply solution is also available.
Please refer to the latest Triton Product Catalogue for power supply types, or call Thomson Grass Valley
for this information.

installed depending on the environmental conditions of the installation site. It is the responsibility of the
installer / user to secure a proper installation of the RS-232 connection.
