Warning
–
This is a class A product. In a domestic environment
this product may cause radio interference in which case the user
may be required to take adequate measures.
Read Instructions
– We recommend that you read this
Instruction Manual prior to commencement of installation.
Power
Sources
– This device should only be operated from the
type of supply specified on the front cover. This device
must
be
earthed.
Output
– The load on this device should not exceed the specified
capacity of 1.5A. This device should be fed via a HRC fuse or
MCB.
Mounting Location
– Install in a dry, well-ventilated location.
Controllers may emit some mechanical noise. Take this into
account when deciding the mounting location.
Data Cable
– Use screened, stranded RS485 data cable with
three twisted pairs. Segregate from mains cables by 300mm
minimum. Connect devices in a ‘daisy chain’. A data cable that is
connected to an energised device is live. Do not cut or terminate
live data cables.
1. Mount the device on a DIN rail inside an approved enclosure.
2. Connect a single phase 0.25A feed to the control circuit supply terminals. This device must be earthed.
3. Connect the two power conductors of data cables to the device. There are two common methods of doing this:
a)
Method 1
: Use a 2 core cable to connect between the DDNP1501 and the data cable connector on a device that is
connected to the network. Parallel connect the GND and +12V terminals on the DDNP1501 to the GND and +12V
terminals on the network device.
b)
Method 2
: Loop the network cable to the DDNP1501 and connect the Green pair to GND terminal and Orange pair to
+12V terminal. Ensure that the other conductors are looped through using a suitable terminal block.
