Non- earth return is available as an option for aluminium vessels to prevent corrosion. All electrical wiring has been prepared on the generating set to the control panel prior to despatch from the factory. The engine is controlled by a very advanced microprocessor based system: Digital Diesel Control. The “black box” containing the microprocessor is located on top of the alternator. A local control panel is on the generating set. Remote control A remote control panel also containing a microprocessor is in the delivery. A 15 m intermediate 8-pole communication cable is in the standard supply too (refer to fig. 13). If necessary an optional longer (up to 30m / 100ft) intermediate cable can be connected if the standard length does not suit the required distance. When Fig. 11: Water trap in exhaust system a longer distance than 30m / 100ft is required, consult the Whis- perPower service department for advice.

M-SQ PRO 15/18 kVA Marine Diesel Generator 2 INSTALLATION SPECIFICATIONS WARNING In all situations the transfer switches between shore, General inverter and generator should switch all connections, the line(s) as well as neutral. Install the generator with the 8 holes ø13 on a rigid surface. Be aware that insulation protection systems can be different for different applications and even within the ship there could be different standards for different spaces. We did refer to the Recreational Craft Directive that applies to pleasure craft up to 24 m of length. Sometimes one has to comply with other standards such as the rules of certification societies like Lloyd’s Register of Shipping or Veritas, regulations for the protection of personal, building legislation, etc. It is of the greatest importance to have expert advice on this issue. For safety reasons connect the main ships ground to negative point of the generating set start battery. When a ungrounded DC system or positive grounded DC system is applied the battery negative should not be connected to the main ships ground. CABLE For the power cable we recommend the use of 3 wire single phase or 5 wire tri-phase oil resistant cable with a sufficient cross sectional area. One wire for earth is included. For long cables it is Fig. 17: Anti-vibration mounts recommended to apply cables with a larger cross section (refer to ISO 13297 annex A) Connect the (sea) water inlet to the strainer.
