Installation And Wiring - Toshiba V Series Operation Manual

Chapter 4 Installation
Fully read this User's Manual and the Ethernet Installation and Wiring Manual
(6F8C0880) before starting installation and wiring.
• For safety, be sure to check that the base unit has been switched off before installing EN6
modules in it or removing them from it.
• Do not apply voltages higher than the rated voltage to the +12 VDC power connector (CN2)
(EN611, EN621, EB621)
• For safety, do not touch the insides of the product except for the switches.
• Make sure that the environment where the product is installed satisfies the product specifica-
tions. In cases where the product is installed in an environment which does not satisfy the
working temperature range, install a cooling unit for forced cooling of the product.
• Be sure to ground Ethernet, segment by segment, by class D grounding. (One point ground-
ing)
• The static charged in the human body may cause the product to fail. Discharge the static
from the human body before starting installation or wiring.
• If the cables are subjected to stress by touching, for example, it may cause malfunction or
accidents. Be careful not to accidentally touch the cables.
• Insert the modular connector fully till it clicks.
• The modular connector is for sending signals through line B in a dual Ethernet transmission
system. Do not connect 10BASE-T by mistake.
• In a dual transmission line configuration, do not make the wrong combination of the main
module (EN621, EN641) and line-B module (EB621, EB641).
• In installing two or more Ethernet modules in the same base unit, be careful not to make a
mistake about the connecting buses and segments.
• When mounting the product into the base unit, be careful not to break or bend the pins of the
bus connectors for the V-series system.
• If it is difficult to install a module in the base unit, do not force it into the base unit. Remove it
once, then try installing it again.
• Use a Phillips screwdriver, which fits the screws. This is important to prevent damage to the
screws.
• In a system of dual transmission line configuration, connect a separate power cable to the 12
VDC power connector CN2 on each module.
• If power cannot be switched on or if other kind of trouble occurs, stop use and contact the
Toshiba service office concerned.
• Verify transmission at the application level using the transmission protocol.
• Make sure that the base unit installed EN651 and EN661 is attached to metallic plate.
• Make sure that the upper side of EN651A module is screwed up by M4 screw.
• If you have any question, contact the Toshiba service office concerned.
