SECTION 8 | Installation
8.9.1.1 2-Wire ON/OFF Control from Remote Location Using Switch/Relay Contact, Fig 8.2(a):
In this arrangement, external voltage source is NOT required. The inverter will switch
ON when potential free relay contact / switch is closed and terminals "S" and "" of
the Terminal Block (4A, Fig 6.1) are shorted. The inverter will switch OFF when the relay
contact / switch is opened and short is removed across terminals "S" and "" of the
Terminal Block (4A, Fig 6.1).
8.9.1.2 2-Wire ON/OFF Control Using Switched DC Voltage (10-33VDC), Fig 8.2(b):
!
CAUTION!
1. Please ensure correct polarity of wiring connection. Positive (+) of the exter-
nal DC source should be connected to the Positive terminal marked "+" on
the 3-Way Terminal Block (4A, Fig 6.1) and the Negative Terminal () of the
external DC source should be connected to the Negative Terminal marked ""
on the 3-Way Terminal Block (4A, Fig 6.1). In case the polarity is reversed, the
ON/OFF control will NOT operate. The input to these terminals is protected
against reverse polarity.
2. Use 1A fuse as shown as close to the DC source as possible.
!
ATTENTION!
1. Veuillez vous assurer que la polarité de la liaison de câblage. La borne
positive ( +) de la source de courant continu externe doit être connecté à
la borne positive marquée " +" ; sur le bornier à 3 contacts (4A, gure 6.1)
et la borne négative (-) de la source de courant continu externe doit être
connecté à la borne négative marquée "-" ; sur le bornier à 3 contacts (4A,
Fig. 6.1). Au cas où la polarité est inversée, le contrôle ON/OFF ne fonctionne
pas. L'entrée à ces bornes est protégé contre les inversions de polarité.
2. Utilisez un fusible 1A comme indiqué aussi près que possible de la source CC

INFO
The 10-33VDC external control signal on terminals marked "+" and "" on the
3-Way Terminal Block (4A, Fig 6.1) feeds to an internal Opto-Isolator. Hence, the
Negative Ground of the external 10-33VDC source will be isolated from the Nega-
tive Ground of the Battery input to the inverter.
i
INFO
Le signal de commande externe 10-33VDC sur les bornes marquées "+" et "-"
sur le bornier à 3 voies (4A, Fig 6.1) alimente un opto-isolateur interne. Par con-
séquent, la masse négative de la source externe 10-33VDC sera isolée de la
masse négative de l'entrée de la batterie dans le variateur.
