Notice:
For the installation, observe that a minimum air gap of ¼ inch (6.4 mm) must
be maintained between the local power cable wires and the network/alarm
cables that are pre-installed by the supplier. A good practice is to cut the local
cable to a suitable size so that it will be led directly (without being wound up)
from the opening in the cabinet to the power connectors (DCIN+/DCIN-). In that
way, the air gap can be kept as shown in the example above.
Note:
Observe the applicable national regulations regarding loop impedance,
voltage drop, and methods of installation. Make sure to connect the correct
voltage to the unit.
Note:
Do not install or deinstall the power wires at the POWER terminal blocks while
power is on. Turn off mains power * before connecting the power wires at the
PSR, then, engage mains again.
* Mains power must be interruptible with an external delayed-actions mains breaker. For the mains
breaker use current state-of-the-art material. The following table can be used as reference but
please make sure that your local requirements / local regulations of the AHJ are kept.
