Installing Heat Reclaim Ventilation
Power Connection Denition
1. Wiring Notice—Shut o Power Prior to Whatever Job.
• The machine must be connected to the ground according EN 60364.
• Circuit breaker capable of shutting power o the whole system shall be installed. Please make sure that earth
connection is available.
• A switch and fuse shall be available for every single power line. Circuit or creepage breaker shall be available
for whatever wiring job.
• Make sure that ground impedance does not exceed 100 ohms. When creepage breaker is available, ground
impeder can be used to accommodate impedance over 500 ohms.
• Power line, connection line, air switch shall be prepared by users.
• Power line model: YZW power line; size must meet local criteria. Must adopt the triple-core shielded wire
with sleeve, such as H05VV-F, H05RN-F, H07RN-F, which are approved by local authority. The size of
the conductor shall not less than 0.75mm2. While connecting the power line, make sure current-carrying
conductors become taut before earthing conductor, if the cord slips out of the cord anchorage.
• Fuse Spec: 15A.
• Power lines of dierent specs shall not be connected to the same terminal. Overheating will ensue in case of
loose terminal connection.
• Power lines of dierent specs shall not be connected to the same ground terminal. Protection will be impaired
in case of loose connection.
• Keep certain distance between power lines and other connection cables to prevent noise.
• For wiring method, refer to circuit diagram. Wiring notice: every cable shall be connected to its corresponding
terminal according to its unique polarity, and shall have its sign matched up with terminal sign.
2. Open and Close Electrical Cabinet
• Before opening the cabinet cover, make sure that power connections to unit components are shut o.
• Unscrew bolts xing the cover and open the cabinet.
• Fix power line with clamp and make sure that earth connection is available. Connect control and signal lines
to corresponding terminal blocks.
• Please use shield wire as signal line.
• Upon completing wiring job, please mount the cabinet cover in good manner.
