Manual EM-box 3 Energy Management Box 12V or 24V The EM-box fulfils the task of an intelligent main current distributor, which distributes charging currents from various charging sources to the connected battery banks with low loss. The engine (alternator and starter), the starter, the service and the optional bow battery are connected to it.

- and passed on to any subsequent owners of the EM-box. Exclusion of liability philippi elektrische systeme cannot monitor compliance with the operating instructions or the conditions and methods of installation, operation, use and maintenance of the EM-box. Therefore, we do not assume any responsibility and liability for loss, damage or costs resulting from incorrect installation and improper operation.
Manual EM-box 3 2. EM-box Introduction and configuration The following diagram shows the basic internal structure of the EM box. The EM-box offers the following basic connection options, which can be deviated from in individual cases or which can be extended by additional configurations.
Manual EM-box 3 2.1 Connection with one engine, one starter battery and one house battery Figure 2.1 shows the installation for yachts with one engine and two battery groups. The positive charging cable between the alternator and the starter motor is already removed, so that a three-wire motor connection to the EM-box is possible.
Manual EM-box 3 From the EM-box the charging cable to the bow battery is connected to connector (8). If the state of charge of the bow battery is to be recorded, a shunt SHC 612 is required in the negative line directly at the bow battery.
Manual EM-box 3 2.4 Connection with two engines, one starter battery and one house and one bow battery Figure 2.4: Anschluss mit zwei Motoren und 1 Starter–Batterie, LM-Strom < 250A Figure 2.4 shows the installation for yachts with two engines and one starter battery. If the total charging capacity of the two alternators is less than 250 A, it is possible to work according to chapter 2.3a with parallel connected...
Manual EM-box 3 2.5 Connection with two engines, two starter battery and one house battery (Power boat/Katamaran) Figure 2.5 shows the installation for catamarans with two engines and two starter batteries. The minus of the STB engine is connected to (-1). The STB starter (+) is connected to the charge output (+8) of the EM-box via an additional remote controlled main switch FBC 265 to switch the starter on and off.
Manual EM-box 3 2.9 Loads If more than 2 high current consumers are to be connected directly to the EM-box, an external bolt fuse distributor (e.g. BlueSea 5196) is connected to the connection (+6). The positive connection (+6) is thus extended for additional loads.
Manual EM-box 3 3. Installation The following parts are required to install the EM-box: a) Fuses for the consumer outputs (pin fuse type SHB, not included in delivery) Connection 6 (vehicle electrical system): (bolt fuse SHB 30, 50, 75, 125, 200 A)

Manual EM-box 3 Important: For all unused outputs, the nut must be tightened so that no error message is displayed by the control LEDs (6a-8a) or the PSM system monitor due to a supposed fuse failure. If two different cable cross-sections are clamped to one bolt, a branch bolt holder ABH1 with fuse as shown in Figure 3.2 must be used in addition, to fuse...
Manual EM-box 3 3.3 Auxiliary connection At the front of the EM-box are the connections for the control and measuring lines and the PBUS. Hardware 3.1 - REV 3B - JAN 20 Page 12...
Manual EM-box 3 3.3.1 AUX-Charging in (Wind, Solar..) (X1) The EM-box offers 2 additional charging inputs for charging currents up to 40 A each (sum of both connections max. 60 A) for alternative energy sources like solar, wind or hydrogen generators.
An M12 T-adapter cable must be connected to the four connections to establish the connection to the P-Bus. All components connected to the P-Bus are connected to each other by P-Bus network cables. See the operating instructions for the philippi system monitor. 3.3.3.2 Ignition cable (X3) If an externally excited alternator is installed on the EM-box at connection 1 (alternator), the ignition plus cable "terminal 15"...
Manual EM-box 3 3.4 Battery disconnect switch Disconnect switch Starter-Battery (A) The main switch of the starter battery disconnects or closes the connection of the starter battery to output +2 (starter motor). Electrical operation is via the system monitor or a pushbutton (see 3.3.2 Main switch control lines). The associated status LED indicates the switching status.
0 Ah (factory setting). As the load currents of the bow battery are not recorded, no battery management is possible. Only the voltage of the bow battery is therefore displayed on the philippi system monitor. If a capacity display is also to be available for the bow battery, an additional battery management shunt SHC 612 must be installed directly on the bow battery.
Manual EM-box 3 On this external shunt, the battery name must be configured to "EM-box-Bug" in order to be recognized as such by the EM-box. The EM-box then detects this shunt and takes over the current, voltage and temperature values for the battery management.
P bus (CAN bus). Manual operation of the main switches directly on the EM-box is also possible in emergencies, A third main switch can be activated for EMERGENCY START of the engine via the service battery, which is switched via the control lines or via the philippi P-Bus. 5.3.1 Emergency start If the starter battery is empty, the engine cannot be started.
Manual EM-box 3 5.4 Fuse monitoring SHB bolt fuses are used for the main protection of the consumer connections. The bolt fuses are electronically monitored by the EM-box at the respective connections. For each connection a red LED indicates the failure of the corresponding fuse (error message).
