Electrical Installation
The WebMasterONE 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. Depending
upon your model code, some relays may be dry contact
and not fused.
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!
