2.3) Installing SUMO (standard procedure)*
1. Use a Philips screwdriver to unscrew the 3 screws of the mobile cover
and remove it (fi g. 4).
2. Thread the wire through the cable holder (fi g. 5).
3. Knock out the two aluminium plates and insert the two cable holders
(21) (fi g. 6).
4a. Lower the release lever with one hand (5).
4b. Block the lever with the bolt (14). (fi g. 7).
5. After identifying on which side the gear motor must be installed,
proceeding as indicated in the preliminary checks, insert SUMO in the
spring holder shaft so that the two grooves coincide. Insert the tab
(31) leaving it projecting from SUMO suffi ciently far for it to be blocked
with the clamp (not supplied) (fi g. 8).
6. Rest the fi xing bracket (41) against the wall and fi nd the best hole for
keeping SUMO parallel with the wall. Fix the bracket to SUMO with a
screw (54) (fi g. 9).
7. Drill holes in the wall over the holes of the bracket and fi x it to the wall
(for this operation, read the following fi xing tips).
8. Hold the release lever with one hand, open the bolt and move it to the
initial position.

Fixing tips (fi g. 9a)
Fixing to steel:
If the bracket must be fi xed to a steel bar use an M8 6.8 or
M8 A2-50 bolt.
Fixing to concrete:
M8 HILTI HST-R-M8 expansion screw
h: 100mm (minimum wall thickness)
h1: 55mm (depth of hole)
Tinst: 25Nm (tightening torque)
hd: 9mm (depth of through hole)
Sw: 13mm (type of wrench)
If the wall is different from the above descriptions (masonry, wood, plastic,
etc.), the fi tter must choose the most suitable fi xing method bearing in
mind that the fi xing system must withstand a traction force of 1000N
(100kg).
2.4) Installing Sumo with vertical chain
Installation for special applications.
This installation system is required if:
- during the preliminary checks it was found that the size of the gear
motor makes standard installation impossible
- during the preliminary checks it was found that the release manoeuvre
could not be performed safely and easily;
- the level of transmitted torque is required to be increased with a further
reduction. (Please consult the builder of the sectional door to discover if
it has been designed to withstand the required torque).
NICE offers the following installation accessories:
CRA1 (shaft with pinion Z = 18)
CRA6 (gear Z = 36)
CRA7 (gear Z = 18)
CRA8 (wall-fi xing bracket)
CRA2, CRA3, CRA4 (suffi cient chain)
For a simple transmission of drive (Ratio 1:1) use: CRA1-CRA7
To reduce drive (Ratio 1:2) use: CRA1-CRA7
Please see fi g. 10 for an example of installation.
- Keep the chain loose slack before fi xing SUMO to the wall, otherwise
after fi xing the cable may be too taut.
- After fi xing the brackets to the wall, the slots allow the position of SUMO
to be adjusted in order to ensure the chain is fairly taut.
Tighten the screws to complete fi xing.
- Make that the pinion and the gear remain at the same level
- The chain must be at least 2.4m from the ground and always positioned
so that it cannot be reached by people’s arms; if this is not possible,
protect it with a safety guard.
!
Make sure that the shaft to which the gear must be splined is
suffi ciently rigid, that is, when subjected to a load of 4000N (400kg)
it does not bend more than 2mm.
Otherwise, suitably strengthen it
2.5) Installing Sumo with horizontal chain
Installation on two-leaf sliding doors
Fig. 11 shows an installation example for driving two sliding wing.
NICE offers the following installation accessories:
CRA1 (shaft with pinion Z = 18)
CRA5 (chain tightening device)
CRA8 (wall-fi xing bracket)
CRA2, CRA3, CRA4 (suffi cient chain)
Please refer to the previous paragraph for installation instructions.
