This equipment must only be installed by qualified
electrical personnel.
Maintenance operations and configuration of this
equipment must be carried out by authorised and
trained personnel.
Once installed and switched on this equipment
may be powered by two different voltage sources.
These two voltage sources are dangerous and are
capable of causing harm to the human body.

Environmental conditions
2
Check the data plate to ensure that the size of the switch and the range of voltage are suitable for the
required application (e.g. 200A, 380VAC to 440VAC).
Ensure that suitable electrical protection (circuit breaker or fuse) is connected upstream of the switch (This
applies to both the mains side and the generating set side).
Read carefully the information provided on the electrical drawing.
Preliminary checks
3
The electrical box has four 7mm diameter holes for wall mounting or affixing to a suitable metallic bracket.
Only use suitable professional materials for the mounting bracket.
The template for mounting the box is shown on the packaging.
The box must be positioned vertically, as shown in the picture opposite. Power connections
are provided through the bottom of the box, regardless of size.
Mounting and Installation
4
Use cables of appropriate length and gauge for the size of the switch taking into account the distance
between the switch D and:
. Mains circuit breaker S,
. Genset circuit breaker M,
. Users load O.
The table opposite shows typical cable gauges used:
Important: The table does not take into account voltage drops in the
cables (caused by distance and methods of installation).
The non-magnetic cable gland plate at the bottom of the transfer
switch is designed to accommodate cable glands with mechanical
latching.
After preparing the cable ends using suitable lugs, connect them to the connection points on the switch
or to the copper busbars while respecting the tightening torque.
Each cable link must have a protective conductor connected to the
enclosure using the available welded studs.
