inaccessible to the user.
AVERTISSEMENT:
Le dispositif doit être installé de façon à ce que l’utilisateur ne puisse accéder
à la connexion de puissance de sortie.
This task applies to all units. Three-phase units will have three mains input terminals
and three load terminals. Two-phase and 1-phase units will have two sets or one set
of mains terminals and load terminals, and will require a reference phase connection
to the A1 board as shown in the connection diagram
.
TO CONNECT LOAD AND AUXILIARY POWER
1. Verify that the Protective Earth conductor is connected.
2. Connect each phase of the mains supply to the mains terminal (
L1
,
L2
,
L3
).
a. Use the screw size specified in
b. Tighten to the torque specified in
.
3. Connect each phase of the load to the load terminals (
T1
,
T2
,
T3
).
a. Use the screw size specified in
b. Tighten to the torque specified in
.
4. For 1PX and 2PX units, connect the reference phase to
A1 X1.3
.
5. Connect a current-limited external power source to the auxiliary power input
connector on the bottom of the unit. Connect either:
◦ 90 VAC to 265 VAC (230 V, 150 mA) to connector
X1
◦ 24 VDC, 1 A to connector
X3
Use the included plug-in, screw-terminal block to make this connection. Follow
the torque recommendation for M2 terminal screws.
6. For HF units, connect the 230 VAC fan power supply to connector
X7
.
Use the included plug-in, screw-terminal block to make this connection. Follow
the torque recommendation for M2 terminal screws.
