Initial start-up
A power module is supplied with the
Vitodens 200 boiler, which requires a
120 VAC power supply from a wall
receptacle.
The module contains a 120/230 VAC
step-up transformer to power the
Vitodens 200 with 230 VAC. Refer to
the Installation Instructions shipped
with the module for wiring details
and/or Installation Instructions of the
boiler.
Voltage range
The voltage at connector
must be
230 V (see wiring diagram).
Neutral conductor
The electrical power supply must have
a neutral conductor.
In Canada all electrical wiring is to be
done in accordance with the latest
edition of CSA C22.1 Part 1 and/or
local codes. In the U.S. use the
National Electrical Code ANSI/NFPA
70. The heating contractor must also
comply with both the Standard for
Controls and Safety Devices for
Automatically Fired Boilers, ANSI,
ASME CSD-1.
Please note:
The outer conductor ”L” and the
neutral conductor ”N” must not be
interchanged.
See wiring diagram in section entitled
”Additional Information” in this
manual.
