Connection of a separate DC Voltage Supply 2.2.2
If a PoE supply is not available, the telephone can also be operated with a DC volt-
age of 24 V to 48 V.
Take off the handset. Unscrew the keypad plate. Guide the supply line through the
screwed cable gland and put the two connecting leads onto the terminals 3 and 4
(any polarity). Fix the supply line with the cable gland. Make sure that the cable con-
nection to the keypad is plugged in. Then place the keypad plate back onto the tele-
phone and fasten it with four screws. Then put the handset back.
Connection of the internal Relay Contact 2.2.3
Take off the handset. Unscrew the keypad plate. Guide the connection line through
the screwed cable gland and put the two connecting leads onto the terminals 1 and
2. Fix the connection line with the screwed cable gland. Make sure that the cable
connection to the keypad is plugged in. Then place the keypad plate back onto the
telephone and fasten it with four screws. Then put the handset back.
Only use lines with a sheathing diameter of 5 mm to 9 mm, since the degree of pro-
tection IP 66 is not ensured otherwise. If you wish to use a separate DC voltage
supply and the relay contact at the same time, you must use a four-core cable.
If a separate DC voltage supply and connection of the internal relay contact are not
required, it is to be ensured that the sealing element is in the screwed cable gland.
