Electric Connection: power, control and communication
Electrical Connection - General Considerations
 Select power supply wire gauge and, as/when needed, external power apparatuses (disconnects, breakers,
etc.) according to equipment electric data (MCA, MOP, etc.), provided on the main label, as well as respective
local and national codes and regulations.
 Equipment (dehumidifier, OACC, OAFC etc.) are accompanied with their respective wiring diagrams, depicting
equipment internal wiring and terminals for external connection (power supply, control terminals, etc.) – refer
as needed.
 Properly seal all penetrations made/used in the equipment cabinet outer walls. Failure to due so may result in
water/humid air infiltration that could lead to equipment malfunction or damage.
 Ensure that all metal shards and filings are swept to avoid possible corrosion or damage to electrical
components. Ensure that wires are properly protected/isolated from the equipment cabinet sharp edges, hot
surfaces, etc.
Equipment Main Power Connection
Main (‘high”) power is to be brought to equipment main PDB (power distribution block, see Pic. H.1 (b)), located in
the main electric panel – refer to equipment labels and manual for panel and PDB location reference. If equipment
has a disconnect, power must be brought there (Pic. H.1(a)) – disconnect would be factory-wired to the PDB or
devices directly. Normally,
OACC and OAFC are
equipped with disconnects,
as well as most LD series
dehumidifiers.
 Verify that proper
voltage and number of
wires (single -phase Vs
three-phase – see Pic.)
are connected to the
equipment – refer to the
main label and submittal
documentation.
CAUTION! When connecting the equipment to external mechanical and electrical systems, refer to
submittal documentation and equipment labels and stickers for piping connection details.
WARNING! All work must be done by qualified/licenced personnel in accordance with local and national
Codes, Standards and Regulations as well as proper field practices, respective design/submittal documentation
and
Dectron
recommendations.
CAUTION! Use copper conductors only. Equipment electrical and control terminals are not designed to
accept other types of conductors. Use of aluminium or other wiring may result in galvanic corrosion and/or
overheating that may cause equipment malfunction and/or failure and would void the warranty.
