2
• These products should be installed by a competent person 
(e.g. qualified electrician) in accordance with these instructions and 
in compliance with the appropriate clauses of the current edition of 
the IEE wiring and building regulations.
• The Weathersafe Isolator range is designed to be mounted on a 
vertical flat surface.
• The rear box shall be mounted on the wall using fixings and wall 
plugs if necessary. The fixing dimensions are marked on the back 
of the rear box.
• The front moulding can only be removed when the switch is on 
the OFF position.
• The terminals should be tightened to a torque of 1.8Nm.
Do not exceed the maximum cables sizes: 
• 20A    2.5mm
• 32A    6mm
• 40A and 63A  16mm2 
• 100A   25mm
• A cable gland of IP65 or higher should be used in order to maintain 
the IP rating.
• The relevant cable entry knockout should be carefully removed by 
scoring the groove around the required knockout with a sharp knife 
and then tapping it out with a small hammer onto a screwdriver in 
the groove.
• When re-assembling the enclosure ensure that the gasket is fully in 
place in order to retain the IP65 rating.
• Tighten the screws supplied to refix the front cover in place. Do not 
overtighten. Use of an electric screwdriver is not recommended.
• Advice should be sought before installing this product in an 
 environment where it is likely to be subjected to chemicals, 
 oils or solvents.
