Table 3-3 Node Am4, Voltage Range & External Breaker - CommScope Node AM4 Manual

Preferably, a minimum cross section of 4 mm
connection.
Each wire must comply with the applicable national regulations regarding loop
impedance, voltage drop, and methods of installation. Make sure to connect the correct
voltage to the unit.
Depending on the Node AM4 power class, please refer for the minimum cross section
of mains cable and external circuit breaker to the corresponding following tables:

Do not connect or disconnect the power cord at the mains connector while
Note:
power is on. Turn off mains power ** before connecting the power cord at the
unit, then, engage mains again.
** Mains power must be interrupted with an external DC breaker.

Please pay attention when installing the mains power cord. To prevent
Note:
heating-up, ensure there is some space between the cables! They must not
be wound up or lay close to each other.
The positioning of the power cable with the
illustrated connector is adjustable by loosening
the 1" lock nut. Use an appropriate torque wrench
(wrench size 27 mm) to observe torque of 2 N-m.
The cable can be turned by maximally 45° to the
left or right from the vertical position as
illustrated. This adjustment degree is irrespective
of the delivery condition which is not necessarily
the vertical position. After the adjustment, tighten
the nut again.
