Area of use 

The Rotator is intended for indoor use only. It is designed for rotating lamps and other electrical 
devices  at  the weight  and  speed  stated  in "Technical  Data".  Any other  use  of the  rotator  may 
result in a risk of injury of persons or equipment damage. Exceeding the load rating may cause 
failure of the equipment. 
Use only approved rigging connectors to secure the load to the  rotator and do not modify the 
shaft  as  this  may  damage  the  rotator  and  result  in  a  risk  of  injury  of  persons  or  equipment 
damage. 
 
Do not modify the rotator. For any modification of your rotator, contact Wahlberg. 
 
It is the customers' responsibility that any local restrictions concerning the use of the rotator are 
complied with. 
 

For indoor use only! 
Caution! To reduce the risk of electric shock or injury: use indoors only 
Caution! To reduce the risk of electric shock, do not expose to rain: store indoors! 

 

 

Using for the first time 

Important!  The  Rotator  281  must  be  protected  from  environmental  factors  such  as  physical 
shocks and vibration during transportation and storage. 

 

Warning!  Read  “Safety  Information”  on  page  2  before  installing,  powering,  operating,  or 
servicing the rotator. Before applying power to the rotator: 

 

Check  the  Wahlberg  Motion  Design  website  at 

www.wahlberg.dk

  for  the  most  recent 

documentation  and  technical  information  about  the  Rotator  281.  Wahlberg  user  manual 
revisions are identified by the revision number in the bottom of each page. 

 

Carefully review the “Safety Instructions” on page 2. 

 

Check that the local AC mains power source is within the rotator power voltage and frequency 
ranges. 

 

See “Power cables and power plug” on page 2. Install a Neutrik powerCON TRUE1 NAC3FX-W 
power input connector on a suitable power cable. If drawing the power from a mains power 
outlet, install a suitable power plug on the power cable.
