Installing Cable Between S
2M
Port and Primary Multiplex Interface (NTPM)
Warning: Power surges, which can occur during
electrical storms, can cause life-threatening electric
shocks or damage/destroy the PBX.
씮
Let a skilled electrician lay all the cables inside the
building.
Requirements
– COMmander S
2M
module
– Enabled NTPM operating voltage on the S
2M
module
in as far as the NTPM is not powered by a separate
power plug. See
Note: When using this operating voltage, the UB+
and UB- contacts on the S
2M
module must be
connected to the NTPM.
– Depending on the manufacturer and the local condi-
tions for one of the following NTPMs:
NTPM (NTBA with connection plate)
NTPMKU (NTBA with T-shaped mounting element
and copper connection)
NTPMKU (NTBA with T-shaped mounting element
and optic fibre connection)
– Distance/line length between devices - maximum of
100 m
– Installation cable (for example, J Y (St) Y nx2x0.6)
with the following characteristics:
4-core or 6-core when using the NTPM operating
voltage on the S
2M
module
unscreened; however: screened for unfavourable
conditions, for example, near a strong transmitter
or an electrical power line
Steps to Take
1.
Attach the wires to the four terminal clamps in the
NTPM.
