Installation

&When connecting external switching

contacts or components to the low

voltage circuit of the control unit, the

safety requirements of protection

class II, i.e. 8.0 mm air gap/creeping

distance or 2.0 mm insulation thick-

ness from 'live' components must be

observed.

&For all on-site components (incl.

PC/laptops), ensure safe electrical

separation to EN 60 335 or IEC 65.

Inserting cables and applying strain relief

Blank off unnecessary knockouts in the lower part of the control unit with cable

grommets (not cut out).
