Lift Blocking Module Installation
Install the Lift blocking module (Part No. 913649E) to position 2 before installing your
2N Lift1
®
(see the figure above) without removing the 2N Lift1
®
cover. Slide the
module into the cut-outs on the motherboard edges and tighten the two screws
(through the panel holes).
Module function
The contact is closed when the telephone line is OK.
Warning
In reality, the "contact" is represented by a semi-conductor with the
resistance of approx. 0.5 Ω in the closed mode. Closing at a voltage value
lower than 9 V may result in troubles – the switch function cannot be
tested using a standard ohmmeter, which only uses small voltage for
metering.
The maximum current to be switched is 1 A. The switch is protected
against higher current values with a resettable fuse.
The allowed voltage is 9 to 24 V DC / AC. The switch is protected against
surges with an overvoltage protector.
The switch "contact" is safely electrically isolated from the telephone line,
but is designed exclusively for low-voltage current applications: cannot
switch
mains voltage. 230 V / 120 V
Caution
Make sure that the screws are tightened properly! both
Caution
The module respoonds to telephone line disconnection with an up to
2-minute delay.
The maximum current to be switched is 1 A. The maximum allowed
voltage is 24 V. It is a mechanical contact (relay).
Warning
The module contact is safely electrically isolated from the telephone line,
but is designed exclusively for low-voltage current applications: cannot
switch 230 V / 120 V mains voltage.
