Electronic Expansion Valve Overheating Controller EC3-X33

Safety Instructions
Read these Operating Instructions carefully. Incorrect use can
result in serious damage to the device and personal injury.
Installation can only be performed by a suitably qualifi ed and
experienced person.
Before starting the installation, all power supply sources must
be disconnected.
Temperatures must be within the specifi ed ranges.
All connections must comply with the applicable electrical
regulations in force.
Th e device must not be connected to voltage until all electrical
connections have been connected.
Warning: Th e EC3-X33 controller is equipped with a renew-
able backup source containing lead and acids. Th erefore, it
cannot be disposed along with normal waste – the battery
is subject to waste recycling regulations. In any case, it must
be recycled in accordance with the applicable regulations in
force (98/101/EEC).

Electrical Connection
Zapojení podle schématu
Th e device may only be connected to the power supply once
all conductors have been connected in accordance with the
wiring diagram.
Th e device cover is grounded to the 6.3 mm terminal.
Warning: To comply with the applicable regulations (especially
CEI 107-70), it is necessary to ensure the following: T trans-
former 24 V AC must be double insulated in Class II. Power
supply 24 V AC is not grounded. To eliminate mutual infl uence
and grounding problems, it is recommended to use separate
condensers for the EC3 and other devices. If connected to
the mains, the EC3 will be destroyed.
