Electrical Connection - Dantherm DV 45-300 Export Livret D'instructions

(fig. 1/2).
On the DV 45-120 units the upper cover plate is
removed and a rope is put through the lifting hook,
after which the unit can be raised and moved.

2.2 Electrical Connection

In order to open the control panel of the DV 45-120
units the four screws holding the door of the control
panel only have to be loosened.
The DV 150-300 units have a service breaker at the
front of the control panel door. This breaker must be
set on „0" before removing the door.
Having opened the control panel access to the following
terminals is obtained (see fig. 3/4).
„INTERN CONTROL". These six terminals are all
designed for connection of OT/Limit/Fan thermostats.
For all units the thermostats are supplied assembled
with cable.
„MAINS". These four terminals L1/L2/L3/N are for
connection of 3 x 400 V to the unit. When connecting
the individual phases it must be observed that the fan
motor is rotating in the right direction (see also
paragraph 3).
Important:
Electrical connection of units without service
breaker (DV 45-120) is to take place through a 3 x
400V 16A Euro-plug. If the power supply is to be
mounted without a Euro-plug a service breaker
must be mounted in the control panel.
„EXTERN CONTROL": An external breaker for control
of fan motor can be mounted between terminal L and
1 (see also wiring diagrams, paragraph 6).
In the standard version terminal 2 has no function.

„ROOM THERMOSTAT": The room thermostat is

„BURNER": The burner is connected by means of a
Wieland plug, which is connected to the terminals 1-
8. Terminal P1 and P2 are exclusively for units with
gas burner for the Danish market. All other units have
a bridge over these terminals.
