1.2. Testing equipment, test bench and tools

Pre-RMA Bench Test Instructions 1. Introduction This document is primarily intended for Victron distributors. It is shared publicly for the benefit of professional installers and others who are comfortable with, and are able to, safely carry out the described tests themselves. In case you are not, this is not a problem. It is not at all required to perform these tests yourself before sending a product to a dealer or distributor for checking or repair. Before submitting a warranty claim, repair request or replacement request (RMA), Victron Energy requires that the unit in question is bench tested by our direct customer (the Victron Energy distributor).

This is to prevent an RMA from being submitted for non-faulty units or units with non-warrantable faults. This document describes the setup and equipment needed to perform a successful bench test and contains testing instructions for most Victron Energy product groups, which need to be completed before an RMA is submitted. The tests described in this document cover all basic functionality. Some lesser-used or simpler-to-test product features are not included. For example, programmable relays, communication ports, remote on/off terminals and so forth. Should these be reported by your customer as faulty, then, of course, bench test for that. 1.1.

Safety The cover of our products may only be removed by a qualified technician with electronic or electromechanical training who is aware of the local safety guidelines and requirements. Before testing a Victron Energy product, always refer to the safety instructions listed in its product manual. Product manuals are available from the product pages on the Victron Energy website . Some basic safety guidelines: AC voltage is dangerous and harmful. Use fused circuit breakers and RCDs. DC voltage is dangerous and harmful. Do not short circuit batteries. When working with batteries, make sure all DC loads are sufficiently fused.

Be aware that lead-acid battery charging can create explosive gasses. Always use electrically insulated tools. 1.2. Testing equipment, test bench and tools To be able to confirm if a Victron Energy product is faulty, it needs to be individually tested. These tests are performed on a dedicated test bench. The test bench contains all equipment needed for the test. Ideally, this test bench is permanently set up in your workshop and readily accessible. The test bench is one of your own design. It contains all relevant equipment that is needed for testing a Victron Energy product. A test bench generally contains the following items: Battery bank and DC power supply. DC loads and AC loads.

DC and AC circuit breakers and automatic fuses. DC and AC electrical cables with a variety of core thicknesses. Tools. Electrical measuring equipment. Computer and a tablet or smartphone. Interfaces and data cables. A peak current limiting resistor is needed to test the SUN Inverter's PV input. Two resistors of 1 Ohm, 200 Watt, are used in parallel for the 12/250 Sun inverter and in series for the 24/250 Sun inverter. Ensure that these resistors are rated in "free air" or alternatively mount them on an appropriate heatsink. Page 1 Introduction

Avoid shorting battery terminals or the DC terminals inside our products. Use insulated nut drivers or spanners to prevent accidental short circuits.

1.2.2. DC source

Pre-RMA Bench Test Instructions Wiha insulated tool set with screwdrivers, nut drivers, pliers, cutters and so on. Use appropriately sized tools and tighten correctly: Almost all nuts, screws and bolts used in Victron Energy units are metric. Please use the appropriately sized tools. Most connection bolts and screws are made of brass, as such, avoid over-tightening. A brass bolt or screw can easily snap. Use a torque spanner to prevent this. The appropriate torque settings are listed in the product manual. If the torque moment is unknown, use this as a guide: M4 bolts, screws and nuts = 1Nm. M5 bolts, screws and nuts = 3Nm. M6 bolts, screws and nuts = 5.5Nm. M8 bolts, screws and nuts = 12Nm.

Avoid over-tightening cabinet screws. You can use automatic screwdrivers but check that you use a middle torque setting. Crimping tools: Ensure that the electrical cables have terminals suitable for the electrical connections that need to be made. Use the correct crimping tool when crimping cable terminals onto cables. 1.2.2. DC source A DC power supply or a set of batteries able to supply 12V, 24V or 48V. DC Power supply: Use a regulated DC power supply that is adjustable between 0-60V and 0-40A, like the DeltaElektronika SM3300 series. A power supply is the preferred option because it is capable of current limiting, thus eliminating the need for DC fusing. Batteries:

If a power supply is not available, use batteries instead. Use four 12V batteries to create a 12V, 24V or 48V battery bank. But be aware that a battery short circuit should be prevented at all times, so DC fuses need to be used as well. For ease of use, use automatic fuses. Multiple voltage battery bank: Please refer to the image below for an example of a battery bank capable of supplying multiple voltages. To maintain balanced and charged batteries, connect a BlueSmartIP65 charger to each individual battery. Page 3 Introduction
