ACM-VLX/VLX/EXP/AXM
This section provides information about mounting the VLX/ACM-VLX and
EXPs/AXMs and connecting power, communications, and I/O.
Each VLX, ACM-VLX, EXP, and AXM consists of a circuit board with a plastic
cover, which has screw holes for mounting. VLXs and EXPs have the same
mounting dimensions. See Figure 10 on page 14. The ACM and AXM have
different mounting dimensions. The AXM has a smaller footprint than EXPs so
it is ideally designed for smaller or crowded enclosures. See the dimensional line
drawings for each device in the "Key illustrations" on page 6.
All VLXs, ACMs, EXPs, and AXMs are suitable for indoor mounting only.
Mount the VLX, ACMs, EXPs, and AXMs in a location and manner acceptable
to the local authority having jurisdiction.
Use a common enclosure to house the VLX/ACM-VLX, EXPs, and AXMs.
Select an enclosure suitable for your application and to the local authority having
jurisdiction. Ensure that the enclosure has a ground bus connected to a ground
known to be suitable for this purpose. See "Single-point grounding" on page 25.
It is acceptable to mount some EXP/AXM modules in a separate
Note
enclosure from the VLX/ACM-VLX, provided the enclosures are immediately
adjacent and the EXP/AXM communication bus runs in conduit that does not
contain any high voltage wiring.
Ensure that the installed location is dry, away from direct sunlight, and free from
excessive dust, vibration, and electrical interference.
For optimum performance, ensure adequate separation of power and
communications cabling. Typically, power cabling is run though one side of the
enclosure (left) and communications cabling through another (right).
Ensure that there is adequate access to units so that technicians can easily:
• Terminate communications and power wiring
• Remove and replace units, if necessary
• Remove the cover, if necessary
• Replace the battery, if necessary
• Replace the fuse, if necessary
• Monitor LEDs during operation
