SAFETY CONSIDERATIONS
GENERAL
This assembly guide must be reviewed for familiarization
with safety markings and instructions before assembly of
the power supply kit.
BEFORE APPLYING POWER
Verify that all components and parts are inserted in
the right location and correct orientation. Verify that
the power transformer wiring is configured correctly to
match the available AC line voltage in your country, i.e.
wired correctly for either 110Volt or 220Volt operation.
SAFETY EARTH GROUND
An uninterruptible safety earth ground must be provided
from the AC power source to your power transformer.
The WARNING sign denotes a hazard. Pay attention
to the procedure, instructions, or the like, which if not
correctly performed could result in damage to your
equipment, electronic component or personal injury.
Any interruption or disconnection, or lack of connection of
the protective earth terminal/safety ground may cause a
potential electric shock hazard that could result in personal
injury. (Grounding one conductor of a two conductor outlet
is not sufficient protection). Connect the safety ground of
your AC wall outlet to the metal case of your power supply
enclosure.
Some voltage adjustments described in this assembly
guide require power to be applied to the power supply
unit.
Capacitors on the power supply board may still be charged
even if the unit has been disconnected completely from it’s
source of power, i.e. unplugged from the wall, or switched
off.
Properly drain the capacitor charge using a bleed resistor
of sufficient power wattage and measure with a voltmeter/
multimeter to verify that no high voltages are present after
disconnection from the main power source.
For continued protection against fire hazard, replace the
fuse(s) with proper rating applicable for your chosen
power transformer VA rating. Do not use repaired fuses
or short-circuit the fuseholder with a wire to bypass the
fuse.
