1. Introduction
1.1 Purpose of Hirose’s guideline
Before using ZERO SCREWTM Terminal Block (EF2 Series), refer to the following guideline describing
precautions on equipment design and work. Note that photos and illustrations in this document
refer to our representative product and differ depending on the product.
The guideline information is subject to change.
2. Precautions
To use the product correctly, read the following Prohibitions/Cautions described in the guideline
before use. In this EF2 Series Guideline, safety precautions rankings are classified as "Prohibition"
and "Caution".
■ Meanings of prohibitions and cautions
Prohibition
Indicates actions that must not be performed because incorrect
handling may immediately result in death or serious injury to the
user.
Caution
Indicates incorrect handling that may result in property damage.
Be sure to observe the following Prohibitions/Cautions.
・Always turn off the power before using the product. Failure to do so may result in an electric
shock or damage.
・Do not touch the metallic parts. Touching the metallic parts this may result in an electric
shock.
・Do not use the product at power-supply voltage and currents exceeding the rating. This may
result in a fire or an electric shock.
・Do not use terminals other than the specified ones. Doing so may result in a contact failure
or ignition.
・As for crimp contacts, keep the insulating distance with insulating tubes so that live parts are
not exposed in order to prevent an electric shock or a short circuit.
・Do not use crimp contacts that are deformed or largely scratched. Using unsuitable crimp
contacts may result in a contact failure or an ignition.
・When using a crimp contact that was previously used for the terminal block, check it for
deformations and large scratches before use. Do not use a crimp contact with deformations
or large scratches.
Replace it with a new crimp contact before use.

・Do not expose the product to vibrations or shocks exceeding the product specifications.
・Do not use our products outdoors because they are designed for indoor applications.
・Remove the edge of the DIN rail end face. Not doing so will cause difficulty in mounting the
product because it gets caught on the edge.
・Do not store or use our products under conditions with corrosive materials that may cause
the physical deterioration of plastic and metal rust.
・If solvent is applied to the product by necessity for improved insulation strength or
protection, check that it will not cause physical deterioration of the plastic before use.
・Salt damage countermeasures are not implemented for our products.
・Use the specified crimp contacts and check them for deformations and contamination,
including oil and contact resistance failure, before use.
・Use the tinned crimp contacts. Check them for abnormalities in inserting/removing force and
contact resistance before use.
・Do not store or use our products in a place close to the sea or under conditions of salt
exposure. If metal rust or significant discoloration is found, replace it with a new one.
・Store and use our products at an altitude of 2000 m or less and within the operating
temperature range, operating humidity range, and storage temperature range described in
this catalog store and use products so that no freezing or condensation occurs.
*Please check the product standards of Our Company on our website.
