Installation

1. 

Fasten wall bracket

Use the wall bracket 

(E)

 as a drilling template.

Use at least 3 screws to fasten the wall bracket. The 
wall should be able to bear a static load of at least 
80 kg.
Recommended: 3 x wall plug, 10 mm, with 8 mm 
screw

If you are need to attach a second housing for 
the MyReserve extension, observe the maximum 
possible gap between the two housings. You will 
find more information in the detailed installation 
and operating instructions. 

 CAUTION

Horizontal installation

 NOTE

Fasteners for wall fixing are not included in the 
scope of delivery.

the hole at the lower left corner of the MyReserve 
Extension housing.

Pull the end of the battery cable which has no plug 
from the cable harness

 through the cable inlet in 

the MyReserve extension housing. In doing so, pull 
battery cable through as far as the red mark and use 
the cable anchorage to tighten and fasten it. 

MyReserve Extension

Remove the dummy plug from the cable inlet in the 
basic housing of MyReserve 800. Screw the supplied 
cable gland

MR Pack 2.2 must form a line with 
the leveling mark.

Install the required number of 
battery modules according to 
the version of the MyReserve.
