3.2 Installation
3.2.1 Rack mounting
The battery charger is 2 rack units high, and is suitable
for a 19-inch rack-mounting installation. Two brackets
for rack-mounting are supplied (see figure 3.3).
Make sure that there is a free space of at least 100 mm
behind the unit for ventilation.
3.2.2 Compliance with standards
Some standards require that each connected appliance
has a fuse. All Plena equipment has an internal fuse for
the 24VDC power supply in each appliance. Please
ensure this is sufficient for your local standard. Also see
figure 3.4 (on the next page) for a schematic
overview of the Plena 24 VDC Battery Charger.
3.2.3 Capacity adjustment
The battery capacity switch influences the maximum
current supplied by the battery charger. Set the battery
capacity switch to the capacity of the battery. The values
are:
• 2 - 4Ah
• 4 - 7Ah
• 7 - 13Ah
•13 - 25Ah
• 25 - 50Ah
• 50 - 200Ah
Once the capacity has been adjusted, it is advisable to
either remove the battery capacity knob or prevent
access to the rear panel. This will prevent the capacity
adjustment from being accidently altered.

Note
The PLN-24CH10 is compliant to the EN54-4
standard for relevant articles. For full
compliance, the installation and other
equipment must also be compliant.
