CONTROL MOUNTING

Mount the ETC to a wall or any flat surface using a combination of any 

two or more of the slotted holes located on the back of the control 

case. The control’s components are not position sensitive, but should 

be mounted so that they can be easily wired and adjusted. Avoid  

excessive conditions of moisture, dirt, dust and corrosive atmosphere.

The ETC has provisions for 1/2 inch conduit connections. The conduit 

hub should be secured to the conduit before securing the hub to the 

plastic housing of the control. When using the conduit entry in the rear 

of the case, a standard plug should be inserted into the conduit hole 

in the bottom. Caution should be 

exercised not to damage the control 

circuit board or wiring when installing 

a conduit connector.

CAUTION

Read all of the information in these instructions before installing 

or operating the ETC control.
The schematic drawings and other information included in these 

installation  instructions  are  for  the  purpose  of  illustration  and 

general reference only.
ETC controls are not to be located in areas of significant moisture, 

dirt or dust as use of the control in such environment may cause 

personal injury or property damage and is likely to shorten the 

control life.
It  is  the  responsibility  of  the  installer  and  the  user  to  assure 

that the application and use of the ETC control is in compliance 

with all applicable federal, state, and local laws, regulations and 

ordinances,  including,  without  any  limitation,  all  requirements 

imposed  under  the  National  Electric  Code  and  any  applicable 

building codes.

PRÉCAUTIONS 

Lire toutes les informations contenues dans ces instructions avant 

d’installer ou d’utiliser le contrôleur ETC.
Les schémas et toutes les autres informations figurant dans ces 

instructions d’installation sont indiqués à des fins d’illustration et 

de référence générale seulement.
Les  contrôleurs  ETC  ne  doivent  pas  être  placés  dans  des  zones 

ayant un taux d’humidité élevé, de la saleté ou de la poussière, 

car l’utilisation du contrôleur dans de tels environnements peut 

engendrer des blessures ou des dommages matériels et est 

susceptible de raccourcir la durée de vie du contrôleur.
Il  est  de  la  responsabilité  de  l’installateur  et  de  l’utilisateur  de 

s’assurer que l’installation et l’utilisation du contrôleur ETC soit 

faites en conformité avec tous les règlements, lois, et ordonnances 

fédéraux,  provinciaux,  et  locaux,  y  compris,  sans  y  être  limité,
