Preparations For Electrical Connection - Maico ER 60 G Mounting And Operating Instructions

11. Installation preparations
3. For a second room connection, produce
the opening in the wall or shaft for the
suction duct [9]. Note installation positions
for the second room connection.
4. Correctly attach main ventilation duct [18]
inside the shaft.
5. Fit ceiling compound for fire protection
systems. To do this, encase the ceiling
and pour in the material from above.
6. Fit duct attachments to ceiling ( Fig. 5).
Only use permitted attachment material.
DANGER
Risk of incorrect installation if non-
permitted attachment material is used.
 Only secure connection duct to ceiling
with permitted attachment material
(duct clamp or clamping band).
7. Connect permitted connection duct [19]
to main duct and seal for ventilation, for
example with cold-shrink tape.
8. Apply wall/board compound [28]. Seal
gap between brickwork and folded spiral-
seams duct. The gap remaining must be
fully sealed with non-flammable materials
resistant to deformation. For example, use
concrete or cement mortar, for wall boards
use fire protection filler.
9. Fit suspended ceiling. With ER-UPD
housings ensure a suitable, flat surface so
that the fan insert can be safely inserted in
the housing later on.
10. Attach spigot made from shaft material
F90 around the shaft.
The spigot compensates for the
length of the shaft walls in the event
of a fire.
11. Lay power cable [20] in line with chapter
11.4.

11.4 Preparations for the electrical
connection
DANGER
Danger to life from electric shock.
 Before laying the power cable, switch
off all supply circuits. Switch off mains
fuse, secure against being accidentally
switched back on and position a visible
warning sign.
Information
● Always note the relevant specifications
for electrical installations and when fitting
equipment. In Germany observe DIN
VDE 0100 and the corresponding parts
in particular.
● Observe ambient conditions ( chapter 8)
and technical data ( chapter 9).
● Note permitted duct cross-section of
max. 1.5 mm².
1. Switch off mains fuse, secure against
being accidentally switched back on
and position a visible warning sign.
2. Lay power cable to the installation
location.
3. Continue with safety check of trigger
equipment according to chapter 11.5.
