Mechanical Pump - Wiring
Dangerous AC voltages that can cause death or serious personal injury are used to power
the product. Always disconnect power before starting any work.
WARNING
General
This device is intended to be connected to UL-listed dispensers equipped with a J-box of
sufficient volume. These connections are not suitable for direct connection to intrinsically safe
devices. All wiring is to be in compliance with NFPA 70 and NFPA 30A.
The wiring for mechanical pumps is provided in two modes:
• Following table lists the wiring in the sequential order of the terminals. This table provides
the signal name and a functional description of the signal.
• Figure 3-12 on page 3-15 shows the wiring list for connection to the terminal, as published
in the wiring label attached to the inner side of the unit. The wiring label follows the
physical location of the wires in the terminal block.
