precautions when installing or servicing Zetron equipment.
•Follow all warnings and instructions marked on the equipment or included in documentation.

short circuit that could cause fire, electrical shock, or equipment damage.
•Remove rings, watches, and other metallic objects from your body before opening equipment. These could be
electrical shock or burn hazards.
•Ensure that a proper electrostatic discharge device is used, to prevent damage to electronic components.
•Do not attempt internal service of equipment unless another person, capable of rendering aid and resuscitation, is
present.
•Do not work near rotating fans unless absolutely necessary. Exercise caution to prevent fans from taking in

Connecting to Consoles
The following table provides connection information for Zetron and third party
equipment. In most cases, one of the modular connectors on the supplied cable must be
cut off to access the wire leads. Each switch closure has been paired to match the pair
assignment of T568 as shown in Table 1.
Warning! The Zetron Desktop Keypad should not be hooked directly to
loads that demand a true contact closure. For more detail,
refer to the switch ratings in Specifications on page 7.

Installation
Figure 2 – Desktop Keypad switch circuits
The “- X -” symbols shown above represent circuit board traces that are used to create a
common reference for all switch common leads. If your application requires each switch
to be isolated then these circuit board traces can be cut. To do so you’ll need to remove
the circuit board from the metal housing as these traces are located on the top side of the
circuit board (the side with the pushbuttons). The traces are located near the connector as
shown above in Figure 2.
