Installation Instructions
Installation Instructions
Step 1: Prepare for Installation
IMPORTANT!
Perform the following steps BEFORE installation of the monitor into the panel.
1. Ensure that sufficient power is available.
2. Ensure that sufficient space is available to allow for proper air flow into and out of the
unit.
3. Ensure that the air temperature around the unit (top and bottom) will not exceed the
rated specifications of the unit.
!
ff The maximum rated temperature for the HIS-ML20 is 50°C (122°F).
ff Remember that heat rises – the temperature at the top of the
cabinet will be much hotter than at the bottom if air inside the
enclosure is not actively circulating. Even in a sealed enclosure,
use of a circulation fan can greatly reduce temperature.
ff Also, remember that even though this product is designed to
operate at 50°C, the life span of any electronic device is shortened
when it is consistently operated at high temperatures. Therefore,
it is wise to take steps to keep the temperature of the ambient air
around the unit as low as possible.
4. Ensure that the ambient humidity of the air around the unit does not exceed the
specifications of the unit.
ff The maximum rated humidity for the HIS-ML20 is 90%
non-condensing.

Warranty Statement
Who is Covered?
This warranty covers the purchaser of this product only and is not transferable without our written consent.
What Does This Warranty Cover and What is the Period of Coverage?
We warrant this product to be free from defects in material and workmanship, subject to the conditions set
forth below. The warranty on all industrial display products, KB-R2 and KB-M2 keyboard series, KVM2
extender series, and ENCL-TC and ENCL-PC enclosure series remains in force for a three year period
beginning on the date we invoice you. The warranty period on KB-PL1 keyboards is two years, and all
other keyboards carry a one year warranty. If Hope Industrial Systems repairs or replaces a product under
warranty, its warranty term is not extended.
What Will We Do to Correct Problems and How Do You Get Service?
We will repair or replace (at our sole option) any part of the unit which proves to be defective. Replacement
parts may be new or refurbished and will meet the same specifications of the original parts or unit. For
orders sold through our U.S. operations, at our expense we will return the product to any location within the
U.S.A. via the shipping method of our choice. Shipping fees for products returned to customers outside
the U.S.A. are the responsibility of the customer. For products originally sold through Hope Industrial U.K.,
return shipping to and from Hope Industrial repair facilities and any EU member country (except Croatia,
Cyprus, and Malta) will be provided using a pre-paid UPS shipping label sent via email. In order to receive
warranty service you must get prior approval from Hope Industrial Systems. To request warranty service
you can telephone us at +1 678 762 9790 or +44 (0) 20 7193 2618 in the United Kingdom or send an email

the shipping box. Hope Industrial Systems will not accept shipments not accompanied by the RMA number.
Except where otherwise noted, you must ship or deliver the product to Hope Industrial Systems Freight
prepaid.

This warranty does not cover equipment which has been damaged due to misuse, abuse, or accident such
as: operating the equipment outside of published specifications; exposure to chemicals or gases not covered
by specified NEMA standards; displaying fixed images for long periods of time resulting in afterimage

contingencies beyond the control of Hope Industrial Systems.
Hope Industrial Systems’ responsibility for malfunctions and defects in hardware is limited to repair and

express or implied, including, but not limited to, the implied warranties of merchantability or fitness for
