1.2 Introduction

The electrical cabinet module protects electrical cabinets for controlling e.g. Midgard winches, cameras and lights on the cages from water intrusion and ensures solid mounting of the electrical cabinet to the cages. The colour makes it highly visible.

2 Interaction with other components

The electrical cabinet module fits ScaleAQ’s universal bracket for extra equipment and is designed to fit electrical cabinets with sizes up to 400x400x200 mm.

3 Installation of the unit

The vertical bracket in the electrical cabinet module is threaded into the universal bracket and mounted with bolts. The U-shaped/curved bracket is threaded around the handrail and secured with bolts in the universal bracket. The electrical cabinet itself can be attached to the steel plate in the electrical cabinet module both before and after the unit is mounted on the pen.

The cables are covered by the cable protectors as shown under the steel plate in the centre photo in Figure 3.1. The two orange plastic covers are closed by threading a steel ring fastened with a tight elastic band over a hook on both sides of the vertical steel plate to which the cabinet is attached.

4 Installation on site

The electrical cabinet module can be easily installed on site and the power box can be replaced when needed when the plastic cover is in the open position.

5 Use

The electrical cabinet module can be used on all pens that have ScaleAQ’s universal bracket installed.

6 Inspection and maintenance

A weekly visual check of the module both inside and outside is recommended to ensure that:

– There are no cracks in the plastic cover that could lead to water intrusion
– The elastic band used to close the plastic covers in vertical position is still tight
– There is no chafing of cables against the steel plate
– All bolts and nuts are still tight

7 Transport and storage

When assembled on site, the parts for the electrical cabinet module are packed as general cargo/europallets. The parts consist of the bracket, U-brackets, steel plate, plastic covers, a package with fastening equipment and cable protection.

8 Manufacturer and product identification

The electrical cabinet module is labelled with ScaleAQ’s logo.
