INSTALLATION

This section provides installation procedures for a WiPS 200 Series wireless network. A wireless network contains a

master transceiver and up to eight remote (i.e. slave) transceivers. I/O Expansion modules provide the network with

additional analog, digital, and pulse I/O capacity. Transceivers and I/O modules are mounted on user-supplied DIN

rail by the installer. Accessories include antennas (omnidirectional and directional as needed), low-loss antenna

cables, connector adapters, voltage transient suppression adapters, and power supplies.

A sample installation is shown in Figure 1. It shows a DIN-rail mounted transceiver and two I/O modules located in

a NEMA 4X rated enclosure. Note the use of a single-point ground system to prevent undesired ground loop

currents. Installation of user-supplied DIN rail and transceiver and I/O modules is discussed later in this section.

The highly directional Yagi antenna, shown below, is used when data transmission over longer distances is

necessary. An omnidirectional whip antenna is used for shorter distances and when a circular radiation pattern is

desired, often due to the wide physical distribution of remote transceivers. Regardless of antenna type, a surge

arrestor is highly recommended, particularly in out-of-doors installations, to protect the connected transceiver from

very large voltages induced by lightning strikes and other electromagnetic events.
