3.5 Electrical Installation

The Webmaster series controllers require the following voltages:

100 –120/200-240 VAC± 10%, 50/60 Hz, 12 amperes maximum

The controller must be connected to its own 15 ampere breaker, close by, to act as an alternate

power shutdown.

Your controller is supplied either factory prewired or ready to be hardwired. Depending upon your

choice of options, you may be required to hardwire some or all of the input/output devices. Please

refer to Figures 4 through 8 for wiring diagrams.

The output loads may be connected to pigtail

(125V prewired) connections or terminal block

(hardwired) connections. The total output current

must not exceed 11 amps. The output relays are

connected in two relay banks each fused at 6.3 amps.

See figure on the right. Assess the steady state amps

of all loads before connecting to controller.

CAUTION! There are live circuits inside the controller even when the power switch on the front

panel is in the OFF position! The front panel must never be opened before power to the controller

is REMOVED!

If your controller is prewired, it is supplied with a 10 foot, 14 AWG power cord with USA style

plug and 8 inch, 18 AWG USA style receptacle cords for the powered relay outputs. A tool (#1

phillips driver) is required to open the front panel.

CAUTION! The electrical installation of the controller must be done by trained personnel only

and conform to all applicable National, State and Local codes!

Note that if 4-20mA type water meters are selected, these are automatically assigned to Input 1

(for makeup water meter) and Input 2 (for bleed water meter). Make sure that the water meters are

connected to the correct terminals on the analog input circuit board (see figure 8).
