Preparing for Main Unit
CHAPTER 2
Installation
This chapter describes the preparation before main unit installation.
This preparation includes work up to power cable connection.
2.1
Safety Precautions
Observe the following precautions when installing the main unit.
Installation of main units must follow the precautions below. Otherwise system may be damaged.
-
Follow the precautions, warnings, and instructions labelled on the main unit.
-
Do not block the vent holes.
-
Do not install the main unit in a location exposed to direct sunlight or close to a device that may generate heat.
-
Do not install the main unit in a location exposed to dust, corrosive gas, or salt spray.
-
Do not install the main unit in a location subject to strong vibration. Install the main unit on a flat surface.
-
Use grounded Category 3 wiring or better. Using another type of grounded wiring may cause abnormal operation.
-
Do not route cables under the main unit. Do not allow cables to become taut.
-
Do not disconnect the power cables while the main unit power is on.
-
If it is hard to push the connector latch of a LAN cable or other cable when attempting to disconnect the cable, push it
with a flathead screwdriver.
Forcibly inserting a finger may cause personal injury or damage the unit.
-
Do not place anything on top of the main unit. Do not work above or on top of the main unit.
-
Prevent rapid rises in the ambient temperature during winter. Such an abrupt temperature change may cause
condensation to form in the main unit. Allow sufficient warm-up time before starting operation.
-
Do not install the main unit close to a photocopier, air-conditioning unit, welder, or other device that generates
electromagnetic noise.
-
Do not install the main unit close to a device that generates large amounts of electrical noise.
-
When installing the main unit, do not connect it to the power supply line for an elevator in the facility, since this would
expose it to sudden voltage drops.
-
Implement antistatic measures at the installation site.
-
Confirm that the power supply voltage and frequency follows rating values labelled on main unit.
-
Do not put any materials in the main unit. The main unit contains high-voltage components. So if metallic matter or
other electro-conductive object enters the main unit through an opening, it may cause a short circuit. This may lead to
fire, electric shock, or damage to the main unit.
-
For details on maintenance of the main unit, contact the distributor where you purchased your product, or your sales
representative.
