• Loading capacity and hardness of the supporting surface, load rating of
mounting bracket should be at least four times the weight of the devices
according to IEC62109-1. and supporting characteristics will be impaired by
wear, corrosion, material fatigue or ageing, This should be calculated by
inspection of the design data of supporting material and consulting
construction engineer.
5.5 Installation steps
Step1: Screw the wall bracket on the wall
• Use the wall bracket as a template to mark the position of the six holes.
• Drill holes with ф8 driller carefully, make sure the holes are deep enough for
install and tight the expansion tubes.
• Install the expansion tubes in the wall, and screw the wall bracket using the
screws in the screw package.
Step 2:Install the anti-theft protection.
Set the cramp ring into the holes of the bracket and inverter on the right side.•
Step3:Hang the ZDNY inverter onto the wall bracket.
Transport the inverter need at least 2 people,each one need to use the handles •
at the sides of the inverter.
Hang the ZDNY inverter onto the bracket,make sure the support on the•
bracket is xed well with the inverter.
Step 4:Install the anti-theft protection
Lock the inverter and the bracket by the cramp ring using a padlock.•
Please store the key carefully in case the inverter needs service.
NOTE!
5.6 Connections of the PV power system
PV String
PV module voltage is very high which belongs to dangerous voltage
range, please comply with electric safety rules when connecting.
WARNING!
When the photovoltaic array is exposed to light, it supplies a D.C
voltage to the PCE.
WARNING!
When there is something wrong with the modules arrays. Modules
can be connected with inverter only after eliminating these problems.
WARNING!
ZDNY series inverters has two input areas”A”and”B”,each with it’s own MPP
Tracker,can be connected in series into 2-strings PV modules.
Please select PV modules with excellent function and reliable quality.
Open-circuit voltage of module arrays connected in series should be <Max. DC
input voltage; Operating voltage should be conformed to MPPT voltage range.
