Connect the incoming supply to terminal block 14 (see

the gure above) in the control panel. Connect the

protective earth directly to the earthing bar, 7 (see the

gure above). When the STAZ-81 energy analyser is

supplied the incoming supply is connected directly

to the energy analyser and strapped from the output

side to screw terminal block 14 (see the gure above).

Each incoming supply must be provided with a

manually operated lockable main circuit breaker/

load interrupter to conform to Machinery Directive

2006/42/EC and Standard EN 60204-1 Electrical

equipment of machines. The load interrupter is availa-

ble as a motor accessory (STAZ-80). The safety circuit

breaker is available as an accessory (APAC). Protect

the incoming power supply of the air handling unit

with a fuse in accordance with current legislation in

the country where the equipment is installed.

block group 14 a (see the gure above) in the control

panel. If the STAZ-81 energy analyser has been selected,

connect the incoming supply directly to the energy ana-

lyser (see page 10). Connect the protective earth directly

to the earthing bar, 7, (see the gure above).

Electrical connections for Norway without transformer, (3x230 VAC)

The power unit can be used without a transformer

in Norway where 3x230 VAC is used. However, the

maximum motor load is lower for each power unit

when using 3x230 VAC; see the table on page 11.

In this case use phase L2 as a virtual neutral. Strap

between L2 and the neutral fuse on the incoming sup-

ply, see connecting on page 9, Fig. 7.

Connect the transformer as illustrated on the right.

Connect the incoming supply 3x230 V to the primary

side and the eQ (400 V) to the secondary side. Position

the transformer so that it has proper ventilation. Maxi-

mum ambient temperature 40°C.

Installation and maintenance instructions

Connecting the service power supply for lighting

All of the air handling unit’s incoming power supplies

must be preceded by a load interrupter in accordance

with Machinery Directive 2006/42/EC. Load inter-

rupters are available as accessories STAZ-80.

In eQ units with integrated controls there are two

options for providing service power for air handling

unit lighting.

1. For power supplies up to 5.5 kW, a service power

supply can be obtained by connecting L3 to L3’

through a terminal block on the power unit in the

control cabinet. This means that the entire air handling

unit is turned off from all power when it is disconnec-

ted through the all pole load interrupter. See Fig. 5.

2. Separate power supply. This means that the air hand-

ling unit still has a service power supply when the all

pole load interrupter is disconnected. See Figs. 4 and 6.

Options 1 and 2 apply if the project’s mains

voltage is 3x400 VAC. If the project’s voltage is

3x230 VAC, connect in accordance with point 2.

In order to achieve service power that takes account

of personal safety in point 2, when the air handling

unit load interrupter is off, the service power must be

supplied from the same group and provided with

a 10 AT double-pole fuse group, and a ground fault

interrupter in series. See Figs. 4 and 6.

If the load interrupter is switched off, service power is

supplied through the residual current circuit breaker,

and when the load interrupter is on, the ground fault

interrupter is bypassed via the load interrupter auxi-

liary contacts.

The service power supply must be connected in ac-

cordance with the enclosed wiring diagram. When

disconnecting the load interrupter, switch off the

double-pole automatic fuse rst, and when the load

has been disconnected the double-pole automatic fuse

can be switched on again. The reverse procedure app-

lies when switching on the load interrupter.
