Series / paralell switch box intallation manual 1.0 - 2002

Installation of the Sidepower series / paralell switch box

Note! To achieve maximum effect, reliability and durability from your Sidepower thruster, a correct

installation as per the instructions are very important. Please follow the instructions carefully, and

make sure that all checkpoints are carefully controlled.

Introduction and planning for the installation of the Sidepower series /

paralell switch box.

The Sidepower series/paralell switch box have been designed to provide a safe and reliable 24V

power for a 24V thruster in a 12V boat.

It has been specially designed and built to accomodate for the high current demands of an electric

thruster and are available in two versions, one for the SP155TC and one for the SP220TC. The only

difference between these two units are the solenoid sizes for the different amp. draw.

It is also designed so that there is no need for additional charging devices and connections, the extra

battery will be automatically charged by the “original” charge feed in the boat for the standard battery

(battery bank) that are being used as “Batt.1”.

There are no need to install 2 special battery banks as one of the boats “standard” banks can be

used as Batt.1, preferably the start battery bank as this is “always” full. The start battery bank is also

preferred as there are normally no electronics that can be knocked out by a voltage drop or peak

caused by all heavy electromtotors such as a thruster.

NOTE ! If you have electronically controlled engines (MMC / Volvo EDC / Morse etc.) the power to

these must not be taken from the same battery as you power a thruster (or any other high power

electric item). The best and most easy way to solve the power feed to such sensitive and critical

items is to make their powersupply a protected one (either by a small extra battery for this, or by a

large condensator / diode pack). It is better, easier and less expensive to provide a seperate power

feed to the electronic engine controls instead of a seperate battery system for the heavy users, as the

electronics have a very small power demand in comparison with a thruster, windlass and the engines

starter motor.

Without exeptions, Batt.2 can have no other connections other than those described in these

instructions.

We advice to install the extra battery (Batt.2) and the series / paralell switch box as close to the

battery (bank) used as Batt.1 as possible.

Make sure to use heavy duty power cables for all battery and thruster connections including the ones

between the batteries and the series/paralell box. The minimum cable size to use is 70mm2 / OOO

or more if required by the length. See list in manual for the thruster you are installing.

The series/paralell switch box is splash proof but must be installed in a dry position so that it can not

become submerged in water.

Observe and follow the minimum battery capasity ratings described here. The smallest rating is for the

SP155 and the largest for the SP200 & SP220. Remember, these are minimum ratings, bigger is

better.

Always install main power switches in the main positive cables from each battery bank so that in

case of a failure or emergency, the power can be switched off. The boat owner / operator must be

informed of the location of these switches and instructed to shut them off when leaving the boat.

We also advice to install fuses at each battery as described in the wiring diagrams.
