Introduction Introduction The CE Filter Box (PN: MS-CEFB) is an EMI (electromagnetic interference) filter designed to control conducted emissions on the AC and DC side of Magnum Energy’s MS-E and MS-PE Series inverters. It is used to ensure that stringent international standards for electromagnetic compatibility (EMC) are met. For specific EU directives and standards see info on the back page. Refer to Figures 1 & 2 below to identify the MS-CEFB filter box’s features.
Introduction Knockouts and Dimensions Right Side 28.7 cm 29.8 cm 27.1 cm 32.1 cm Top 14.5 cm 16.8 cm Front 20.3 cm Note: All four mounting holes are approx. 6.4 mm (¼”) The MS-CEFB provides knockouts for use with ¾” and 1” trade size* conduit, and adds just over 20 cm to the length of the inverter (see Figure 3). * – “Trade size” refers to standard North American conduit. Actual openings are approximately 2 cm and 2.7 cm. 16.5 cm Left Side 7.

Installation Installation CAUTION: Before installation, closely read and review all safety information and procedures in this guide and in your inverter owner’s manual. WARNING: The inverter uses power from both AC and DC sources. Before beginning the installation, ensure all AC power (utility/generator) and any negative/positive battery cables are safely disconnected from the inverter. Review the simplified system diagram shown in Figure 4 to assist you in planning and designing your installation.
Installation MS-PE or MS-E inverter Remove AC access cover (#2 Phillips*) * Tool needed to remove Remove DC +/- terminal nuts (1/2” Hex*) Remove DC ground hardware (7/16" Hex*) Remove cover screws on each side (#25 Torx*) Stage I – Prepare Inverter Stage II – Connect Filter Box to Inverter Note: Before re-attaching the inverter’s DC terminal nuts, ensure the filter’s DC busbars are properly fitted over the terminal bolts.
Installation Installing the MS-CEFB Prior to installation of the filter box, the inverter/charger must be prepared. To prepare the inverter (Figure 5, Stage I): 1. 2. 3. 4. Remove the inverter’s AC access cover (will need access to inside the inverter to remove the DC ground connection and to wire AC connections). Remove the inverter’s DC positive and negative terminal nuts/washers.
Installation To wire the inverter’s AC terminal block (top of Figure 7): 11. Route the filter box’s AC input/output wiring through the appropriate knockouts/strain reliefs on the inverter, and then connect to the inverter’s AC terminal block. • • • • Connect wire A (white w/ black stripe) to Terminal #1 (AC NEUT OUT). Connect wire B (blue) to Terminal #2 (AC HOT OUT). Connect wire C (black) to Terminal #3 (AC HOT IN). Connect wire D (white) to Terminal #4 (AC NEUT IN).

Installation To wire the MS-CEFB filter box to the battery bank: 1. Route the end of the positive DC battery cable from the battery bank through the supplied red DC terminal insulator (do the same for the negative DC cable – using the black DC terminal insulator). The insulators protect the MS-CEFB’s DC terminals and can help prevent accidental shorts.
Installation To attach the ferrite core to a communication cable (Figure 9): 1. 2. For each communication cable, route one end through the ferrite core and wrap it several times around/through the core. There needs to be at least three full turns around the ferrite core. While wrapping the cable around the core, ensure the core is located as close as possible to one end of the cable [within 2.5 to 5 cm (1-2 inches) from the end]. The result should look something like Figure 9 below.
EU Standards/Limited Warranty EU Directives and Standards A MS-CEFB (CE Filter Box) connected to a MS-E or MS-PE Series inverter/ charger conforms to the provisions of EMC Directive 1999/5/EEC, per: • EN 55014-1 (2006) +A1, +A2, (> 1000W) Electromagnetic compatibility – Requirements for household appliances, electric tools and similar apparatus — Part 1: Emission • EN 55014-2 (1997) +A1, +A2, Electromagnetic compatibility – Requirements for household appliances, electric tools and similar apparatus — Par
