Important safety instructions for 
installation

WARNING

 Incorrect installation can lead to severe injury. Follow all installation 

instructions.  Merlin  Garage  Openers  Limited  does  not  accept  responsibility  for 
damage or injury resulting from installing this opener.

Prepare the gate for safe automation

Before  installing  the  drive  remove  or  disable  any  equipment,  such  as  locks,  that  is  not 
needed for powered operation. 
Check that the gate is in good mechanical condition and that it opens and closes properly. 
Do  not  use  force  sensitivity  adjustments  to  compensate  for  a  binding  or  sticking  gate. 
Excessive force may damage the gate.

Avoid possible entrapment points

Ensure that entrapment between the driven part and the surrounding fixed parts due to the 
movement of the driven part is avoided.
Gaps are considered safe as follows (IEC60335-2-103): finger gaps above 25 mm; foot 
gaps above 50 mm; head gaps above 300 mm; and whole body gaps above 500 mm.

Add over-ride switch if wicket gate is present

If a wicket gate is present in a gate leaf, it must be fitted with a switch that prevents the 
drive from operating when the wicket is open. (Connect a Normally Closed switch to the 
STP and GND terminals of the controller board.)

Locate controls carefully

Install any fixed control, wired or wireless, within sight of the gate but away from moving 
parts and at a height of more than 1.5 m.

Fit non-contact safety beams

Where they are not already explicitly required to comply with regulations, Merlin strongly 
recommends fitting non-contact safety beam sensors.

Locate the entrapment warning sign correctly

After installing the drive, the included entrapment warning sign must be fitted within sight 
of anyone that may stand in the path of the moving gate.

Inspect and test the installation

After  installation,  ensure  that  the  mechanism  is  properly  adjusted  and  that  and  the 
protection system and manual release function correctly.

Educate the owner

Before handing controls to the user, alert them to the potential dangers, and routine checks 
they’re required to perform.

Complete the commissioning check sheet

The  commissioning  check  sheet  at  the  end  of  this  manual  must  be  completed,  signed 
by  the  installer  and  client,  and  kept  on  record  by  the  installing  company.  It  contains  a 
declaration that all safety related procedures have been complied with.
