2.4 Mounting the power unit chassis,
connecting with the MACH4000 device
Note: The power supply cables between the M4-POWER power unit chassis
and the MACH4000 device are not hot-swappable.
Note: The power supply cables between the M4-POWER power unit chassis
and the MACH4000 device carry system-internal safety extra-low voltages.
Only use the M4-POWER CABLE and the M4-POWER power unit chassis
for the redundant power supply. Do not connect any other external voltage
source.
Consider the sequence for the cabling of the power unit chassis and the
MACH4000 device:

Separate the external power supply from the M4-POWER power unit
chassis.

Remove all the plug-in power units from the M4-POWER power unit
chassis.

Connect one end of the M4-POWER CABLE to the MACH4000 device.

Connect the other end of the M4-POWER CABLE to the M4-POWER
power unit chassis.

Connect the MACH4000 device and the M4-POWER power unit chassis
with the mounting bracket included in the delivery.

Slot all the plug-in power units into the M4-POWER power unit chassis.

Connect the external power supply (AC or DC, depending on the plug-in
power unit) with the M4-POWER power unit chassis.
NOTE
SHORT-CIRCUIT
Insert the plugs of the power supply cables in straight in order to avoid the
bridging of pins on the power supply connection of the MACH4000 device.
Non-adherence to these instructions can lead to material damage.
