Chapter 1: Installation

Connections

Power input

AC power input for the CDC4 is provided via the two AC terminals. Power is
typically provisioned from the transformer fitted to the enclosure in which the
CDC4 is installed. The CDC4 AC voltage requirements are specified in
"Specifications" on page 41. The enclosure installation manual provides further
details for the transformer, along with fuse location and specifications.
The transformer leads supply high currents to the board. Poor connections lead
to excessive voltage drop and can affect system performance. At the board
connection, the installer must ensure that:
•
Terminal wiring is performed with the transformer power input disconnected
•
The bare wire ends are neatly dressed and fully inserted into the terminal
housing. Less than 2mm of exposed wire should be visible after termination.
•
The complete bundle of wire strands is inserted into the screw terminal. No
broken strands should be visible.
•
There are no free strands outside of the metal block in the terminal housing.
•
The retaining screw is correctly torqued.
WARNING! Ensure that the transformer primary cable is connected to the mains
terminal block. Accidentally connecting secondary (19.5 V) cable to mains will
result in hazardously high voltage.

Batteries

The door controller requires battery backup to maintain functionality when
primary power is lost. Two independent battery channels are provided for this
purpose. Key battery requirements are listed in "Specifications" on page 41. The
table does not specify battery dimensions, capacity and temperature ratings as
they are installation dependent. The installer is responsible for ensuring that:
•
The specified battery or batteries, in conjunction with the configured system
load and charger settings, provide the required system backup and recharge
times.
•
The battery operating temperature range is compatible with the specific CDC4
installation environment; a minimum range of 0°C to +40°C is recommended.
•
The batteries fit into the system enclosure and are oriented so that there is no
possibility of their uncovered terminals being bridged by metal when the leads
are not attached.
•
The system enclosure is properly sited and mounted to handle the configured
system weight and allow for safe installation and removal of the batteries in
