MOUNTING INSTRUCTIONS
Preparation
Before connecting all wiring, please take off the bottom cover by removing four
screws as below.
Mounting the Inverter
Step1: Drill holes on the wall
• Locate the appropriate drilling holes and mark it with a marker pen.
• Drill holes with driller, make sure the holes are deep enough (at least 50mm) to
support the inverter.
Step 2: Install the inverter to the wall
Insert the expansion tubes into the holes and tighten them. Then install the inverter
by screwing the screws
ELECTRICAL CONNECTION
This chapter mainly describes the cable connections of the system.
Prior to any electrical connections, keep in mind that the inverter has dual power supplies. It is mandatory for the qualified personnel to wear
personal protective equipments (PPE) during the electrical work.
DANGER
Danger to life due to a high voltage inside the inverter!
• The PV string will generate lethal high voltage when exposed to sunlight.
• Before starting electrical connections, disconnect the DC and AC circuit breakers and prevent them from inadvertent reconnection.
• Ensure that all cables are voltage free before performing cable connection.
WARNING
• Any improper operations during cable connection can cause device damage or personal injury.
• Only qualified personnel can perform cable connection.
• All cables must be firmly attached, undamaged, properly insulated and adequately dimensioned.
NOTICE
• Comply with the safety instructions related to the PV strings and the regulations related to the utility grid.
• All electrical connections must be in accordance with local and national standards.
PV CONNECTION
Please only use the PV connectors from the accessory box for connection. Before connecting, please make sure:
• The voltage, current and power ratings of the panels to be connected are within the allowable range of the inverter. Ensure polarity is correct. Please
refer to the Technical Data in chapter 9 for voltage and current limits.
• Since the inverter is transformerless, please do not ground either output of the PV panels. Ground the panel frames.
• Before connecting to PV modules, please install separately a DC circuit breaker between inverter and PV modules.
• To avoid any malfunction, do not connect any PV modules with possible current leakage to the inverter. For example, grounded PV modules will
cause current leakage to the inverter. When using CIGS modules, please be sure NO grounding.
• It's requested to use PV junction box with surge protection. Otherwise, it will cause damage on inverter when lightning occurs on PV modules.
Please follow below steps to implement PV module connection:
Step1: Remove an appropriate length of the insulation layer from the positive and negative power cables using a wire stripper.
Step2. Insert the exposed areas of the positive and negative power cables into the metal terminals of the positive and negative connectors respectively
and crimp them using a crimping tool.
