If you choose to install your PQube in an enclosure, select a UL-listed enclosure that is appropriate for the purpose, such as the
Altech EK series (www.AltechCorp.com). If you plan to use an enclosure of this type, you should review its mechanical
compatibility with any optional features of your PQube that you plan to use: optional USB connections, optional temperature-
humidity probes, etc.
A different example of how to correctly protect your PQube operator from the screw terminals. A 6,35mm (0.25 in) clear
Plexiglass
®
sheet, which requires a tool to remove, protects the operator. A rectangular cutout in the Plexiglass gives the operator
access to your PQube controls, the Ethernet connection, etc. Note the 1-amp, 3-phase circuit breaker, at far right, used both as
external overcurrent protection and disconnecting device, near your PQube. The rectangular opening in the Plexiglass should be
74mm x 47mm (for your PQube alone), or 110mm x 47mm (for your PQube and the ETH1 module, or your PQube and the PS1
module), or 146mm x 47mm (for your PQube and both the ETH1 and PS1 modules).
Protect antenna terminals from lightning
If you install a PQube antenna (GPS, Zigbee, etc.) in an outdoor location where it may be exposed
to lightning, you must include a properly installed UL-497C-listed lightning protection device on the
antenna cable. Follow all local installation safety requirements and
regulations.
Installing Your ETH1 Ethernet Module
The optional ETH1 Ethernet module connects to the left side of your
PQube; just snap it in. Connect the module before supplying power to
your PQube. The ETH1 Ethernet module contains a standard RJ-45
Ethernet port. The module uses 10BaseT Ethernet with built-in crossover
detection. You can connect your ETH1 Ethernet module to any standard
