TDK 1500W, 750W technical manual Safety Instructions

SAFETY INSTRUCTIONS

CAUTION

The following safety precautions must be observed during all phases of operation, service and repair of this equipment. Failure to comply with the safety precautions or warnings in this document violates safety standards of design, manufacture and intended use of this equipment and may impair the built- in protections within.

TDK-Lambda Americas Inc. Inc. shall not be liable for user’s failure to comply with these requirements.

INSTALLATION CATEGORY

The GenesysTM power supply series has been evaluated to INSTALLATION CATEGORY II. Installation category (over voltage category) II: local level, appliances, portable equipment etc. With smaller tran- sient over voltage than Installation Category (over voltage category) III.

GROUNDING

This product is a Safety Class 1 instrument. To minimize shock hazard, the instrument chassis must be connected to an electrical ground. The instrument must be connected to the AC power supply mains through a three conductor power cable, with the ground wire firmly connected to an electrical ground (safety ground) at the power outlet.

For instruments designed to be hard-wired to the supply mains, the protective earth terminal must be connected to the safety electrical ground before another connection is made. Any interruption of the protective ground conductor or disconnection of the protective earth terminal will cause a potential shock hazard that might cause personal injury.

WARNING

OUTPUT TERMINALS GROUNDING

There is a potential shock hazard at the RS232/RS485 and the IEEE ports when using power supplies with rated or combined voltage greater than 400V and the Positive Output of the Power Supply is grounded. Do Not connect the Positive Output to ground when using the RS232/RS485 or IEEE.

FUSES

Fuses must be changed by authorized TDK-Lambda Americas Inc. Inc. service personnel only. For continued protection against risk of fire, replace only with the same type and rating of fuse. Refer to Chapter 9 for fuse ratings.

INPUT RATINGS

Do not use AC supply, which exceeds the input voltage and frequency rating of this instrument. The input voltage and frequency rating of the GenesysTM power supply series is: 100-240V, 50/60Hz. For safety reasons, the mains supply voltage fluctuations should not exceed +/-10% of nominal voltage.

LIVE CIRCUITS

Operating personnel must not remove the instrument cover. No internal adjustment or component re- placement is allowed by non-TDK-Lambda Americas Inc. Inc. qualified personnel. Never replace com- ponents with power cable connected. To avoid injuries, always disconnect power, discharge circuits and remove external voltage source before touching components.

PARTS SUBSTITUTIONS & MODIFICATIONS

Parts substitutions and modifications are allowed by authorized TDK-Lambda Americas Inc. Inc. ser- vice personnel only. For repairs or modifications, the instrument must be returned to an authorized TDK-Lambda Americas Inc. Inc. service facility.
