SAFETY INSTRUCTIONS

“Safety instructions” refers to instructions whose specific

intent is to avoid the risk of personal injury and to prevent

damage to equipment.

Danger! Electrical current to electrical components!

Note: Switch off main power before removing the cover.

Never touch electrical components or contacts while main

current is switched on. Risk of electric shock, resulting in

serious injury or death.

Connected terminals contain residual voltage even after

the main current has been switched off.

The following symbols and references will be used in this description. These

important instructions apply to personal protection and technical safety during

operation.
