Safety Precautions
Refer to Safety Precautions for All Relays.
■ Mounting
Make sure that the Relay is free from iron powder or iron core,
otherwise the iron dust may adhere to the Relay. As a result the
movable contact may not operate properly.
An arc may be generated between the contacts in switching
operation. Be sure to keep combustible objects away from the Relay.
If the arc will have a bad effect around the Relay, the use of a model
with a casing is recommended.
A model switching DC load incorporates an insulation base with a
small built-in permanent magnet. Be sure to keep magnets or ferrous
objects away from the permanent magnet, otherwise the capacity of
the maximum switching current may drop.
The PL Back-connecting Socket must be flush-mounted from the
surface of the panel.
If two or more Relays are mounted together, make sure that a
minimum space of 20 mm is provided between adjacent Relays.
Be sure to mount the Relay so that the movable contact is in the
downward direction.
■ Connection

Screw Terminal Model
Do not bend the coil terminals, otherwise the coil wire may be dis-
connected. Make sure that the tightening torque applied to each ter-
minal is 1.27 N • m and the insertion force is 49 N for 10 s.
Solder Terminal Model
Make sure that Relay terminals are free of flux or other foreign sub-
stance before soldering the Relay terminals. Finish soldering the
Relay terminals quickly, otherwise the coil wire may be broken.
switching DC loads (“X” models), consider the polarity of the con-
tact terminals so that the generated arcs on the adjacent poles will
not collide. (For example, if the common connections of the Relay
are all positive or all negative, no arc collision will occur.)

gas to escape. This, however, makes it possible for dust and dirt to
enter the case. Be sure to use the MM@XKP in a suitable
environment.
