POW-AD22GY, POW-AD13GY
Compliance Requirements
The low voltage directives require that devices operating from power supplies in the range 50 - 1000
VAC or 75 - 1500 VAC observe necessary safety precautions.
The following describes the main points to note so that installations using the POW-AD22GY can
comply with the low voltage directives.
Although this information has been prepared to the best of our ability based on the requirements,
standards, and other stipulations contained in the regulations obtained by CONTEC, we provide no
guarantee that equipment manufactured based on this information will comply with the above directive.
Ultimate responsibility for determining how to comply with the low voltage directive and how to
confirm compliance is the responsibility of the equipment manufacturer.
POW-AD22GY is an open-type device (a device designed to be housed inside other equipment) and
must always be mounted inside a control panel according to standard EN60950. To provide electrical
shock protection for people such as operators who do not have the necessary level of electrical
knowledge, the control panel must include the following precautionary measures (Installation
category:2).
(1) Electric shock protection
(a) Lock the control panel to ensure that it can only be opened by persons with sufficient knowledge
and training on electrical equipment.
(b) Incorporate a mechanism so that opening the control panel automatically isolates the power
supply.
(2) Water and dust proofing
The control panel is dust- and water-proof. If dust-proofing or water-proofing is made inadequate,
insulation may deteriorate increasing the risk of insulation failure. The insulation on the POW-AD22GY
is designed to deal with pollution degree 2 and therefore the unit should only be used in environments
with pollution degree 2 or better.
Pollution degree 1: Dry environment with no conductive dust or other contamination.
Pollution degree 2: Environment in which conductive dust or other contamination does not normally
occur, but where conductive contamination may occur from time to time due to
accumulation of dust or similar. Typically the environment in an IP54 equivalent
control panel in a factory control room or factory floor.
Pollution degree 3: Environment in which conductive dust or other contamination does occur and
where conduction may occur due to accumulation of dust or similar. Typically a
factory floor environment.
Pollution degree 4: Environment in which conductive contamination such as rain or snow is always
present. An outdoor environment.
As described above, if a POW-AD22GY is housed in an IP54 equivalent control panel, contamination
level 2 can be achieved.
(3) Installation Requirements
(a) Build in this power supply according to standard EN60950 which is a built-in power supply.
(b) Installation category:2 (Pollution Degree 2)
(c) The protection earth point is FG pin of 100 - 240VAC connector in front of the case. Ground this
pin to the earth with the cable.
