DANGER:
RISQUE DE MORT OU DE BLESSURES. Débrancher et verrouiller/étiqueter
toutes les sources de puissance d’entrée avant de travailler sur cet appareil
ou sur tout élément qui y est raccordé.
WARNING:
This device must be installed so that the output power connection is
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 (see
on
page 5
‑
33).
☞
Important
If the unit is operated without an output load at over 600 V, the output voltage
can exceed the maximum input voltage, damaging the unit. In this case, an
optional 690 V snubber board (part number 2000003203) must be connected to
each output. One snubber board is required for 1-phase and 2-phase units; two
snubber boards are required for 3-phase units wired in an open delta
configuration.
TO CONNECT LOAD AND AUXILIARY POWER
1. Press on the retaining clip on the front of the unit(s), and slide the plastic
cover(s) forward to remove.
2. Verify that the Protective Earth ground conductor is connected.
3. Connect each phase of the mains supply to the mains terminal (
L1
,
L2
,
L3
).
☞
Important
A clockwise rotating field is required. The mains terminals are labeled
1
on units with less than a 45 A current rating.
a. Use the screw size specified in
b. Tighten to the torque specified in
4. Connect each phase of the load to the load terminals (
T1
,
T2
,
T3
).
☞
Important
The load terminals are labeled
2
on units with less than a 45 A current
rating.
