!
Electrical equipment may only be used on the pole access ladder under the following conditions:
> With protective low voltage (48 V).
> With protective insulation (separation transformer).
> If the equipment is connected via a ground fault circuit interrupter with a residual
current of max. 30 mA.

BEARING UNITS
!
Pole access ladders may only be used in the vicinity of such units if the following conditions are met:
> The unit must be disconnected and secured against being switched back on.
> The section of the unit in question must be de-energised.
> The section of the unit must be earthed by means of an earthing strap.
> The section of the unit must be insulated against any adjacent current-bearing
components.

ANGER OF ELECTRIC SHOCKS WHEN WORKING IN THE VICINITY OF OVERHEAD POWER LINES
!
> When working near overhead power lines, observe the safety clearances listed in
the table below.
> When calculating safety clearances, allow for the swinging radius of power lines
and the movement radius of working personnel. The movement radius includes
any objects held by personnel.
> If it is not possible to comply with the safety clearances, have the operating authority
disconnect the power lines and secure them against being switched back on.
Rated voltage (V) Safety clearance (m)
< 1000 V 1.0 m
1 kV – 110 kV 3.0 m
110 kV – 220 kV 4.0 m
220 kV – 380 kV or if the rated
voltage is not known 5.0 m
