CAUTION
To prevent possible electrical shock or equipment damage, disconnect
electrical power to the unit before and during installation. DO NOT restore
electrical power to unit until the control is properly installed and the cover
is assembled. DO NOT locate the control in an explosive atmosphere as
a safety hazard can result due to possible spark generation in the control.
Controls are not to be located in areas of significant moisture, dirt or dust,
or in a corrosive explosive atmosphere. Use of control in such environ-
ments may result in injury or damage to the persons or property (or both)
and are likely to shorten the control life;
Ranco assumes no responsibility for any such use.
INSTALLATION INSTRUCTIONS
IMPORTANT
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, and corrosive atmosphere.
1. All ETC series controls are designed as operating controls only. If
an operating control failure could result in personal injury or loss of
property, a separate safety control and /or alarm should be installed.
2. The schematic drawings and other information included in these
installation instructions are for the purpose of illustration and general
reference only.
3. These instructions do not expand, reduce, modify or alter the Ranco
Terms in any way; and no warranty or remedy in favor of the customer
or any other person arises out of these instructions.
4. Ranco ETC controls have been approved by Underwriter's Laboratories
as UL listed; however, approval does not extend to their use for any
other purpose. Ranco assumes no responsibility for any unconventional
application of its control unless such application has been approved in
writing by Ranco.
5. It is the responsibility of the installer and the user to assure that his or
its application and use of all Ranco products are in compliance with all
federal, state and local requirements, including, without any limitation,
all requirements imposed under the National Electric Code and any

CONTROL MOUNTING
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.
