Challenger10 Installation and Quick Programming Manual
Before you begin
This section contains items that govern the installation of many different
Challenger system devices (including but not limited to the Challenger panel).
When installing a Challenger panel, or any other parts of the system, you need to
be aware of requirements for cabling and earthing, and plan accordingly.
NOTICE!
A qualified service person, complying with all applicable codes, should
perform all required hardware installation.
Disclaimer:
This manual contains recommendations based on Australia and
New Zealand codes. It is not an authoritative reference regarding codes and has
not been reviewed by the responsible authorities. The codes may change and
may not be reflected in this document.
Cabling requirements
This section contains recommendations for installers and electricians for the
application and wiring of Challenger equipment with respect to:
• System earthing
• RS-485 data cable (LAN) cabling
• Power supply from LAN or from external 12 V supply
System earthing
The following recommendations are based upon Australian wiring regulations
AS/NZS 3000:2000 Section 5.
• Each device’s GND link (if applicable) must be removed.
• Connect the 230/16 VAC plug pack earth conductor to the Challenger panel’s
earth terminal (Figure 5 on page 11, item 3). Do not extend this wire to any
device outside of the enclosure.
• Some Challenger devices have an earth lug (or stud) on the PCB and are
fitted with a link labelled “GND” or “EARTH”. In such cases, the device’s GND
or EARTH link must be removed. When configured correctly, there will be a
resistance value greater than 100 kΩ between the device’s earth lug (or stud),
or power earth terminal (similar to Figure 5 on page 11, item 3), and any “C”
or “0V” terminal on the device.
• Install LAN isolation devices between multiple buildings and maintain
independent earthing systems. For example, use TS0893, TS0894, or
TS0896 Isolation Interface modules to provide electrical isolation and/or to
extend distance.
Earthing of one cabinet containing several devices.
All devices designed for
the system have earth connections via metal studs to the metal housing. Take
care that these metal studs have a good connection to bare metal (no paint).
