Installation Sheet
Panel Mount
Rev. 101016
EL Series
AC & DC Output SSRs
This installation sheet includes detailed mounting and wiring instructions which apply for most EL series SSRs.
Be sure to visit the product series' datasheet available at the Crydom website to complement this information.
If you have questions or need additional information please contact Crydom Tech Support.
(A) Load can be wired to either terminal 1 or terminal 2. Proper polarity must be observed for
the DC control power supply with terminal 3 being positive with respect to terminal 4.
(B) Inductive loads should be diode suppressed to prevent damage to the relay.
Transient Protection
Transients are common on AC power lines, and in extreme cases, may pose a risk for the
proper operation and reliability of the SSR and its load.
The load which the SSR controls may also generate transients itself. Therefore, inclusion
of transient protection for the SSR is highly recommended.
Internal transient protection is standard in certain Crydom SSR models, and optionally
available in others. The user may also install transient protection external to the SSR for
additional protection.
An inductive load will produce harmful transient voltage when it is turned off. The more
perfect the switch, the larger the transient voltages. The MOSFET output is so nearly
ideal switch that the transient voltages produced by seemingly “non-inductive” loads
can cause damage if not suppressed. Diodes should be fast recovery type with PIV rated
greater than supply voltage.
(B)
Terminals
Quick Connect type. Input: 3/16" x 0.032". Output: 1/4" x 0.032".
Please read all mounting instructions before using your AC or DC Output Panel Mount Solid State Relay (SSR).
Important Considerations
Be sure to use input and output voltages within operating ranges.
LED indicates only input status. It does not represent output status.
MOUNTING INSTRUCTIONS
Mounting on Heat Sink
Mounting on Panel
Choose one of the two mounting options and follow the instructions.
Locate the panel section on which the EL will be mounted. Panel mount surface must provide adequate
heat sinking capability, uncoated, clean, flat (0.004 in/in recommended) and preferably aluminum.
Be sure that thermal pad is pre-installed before installing over the panel.
EL series SSR mounting slots have a diameter of 0.2 in (5.0 mm). Two screws are needed (not included)
to mount the EL onto panel. Choose screw length considering the mounting surface hole depth and that
the SSR flange thickness is 0.125 in (3.2 mm).
Before applying full torque tighten down both screws until they contact the baseplate. Then, tighten
them to 10 in-lb (1.13 Nm).
Select adequate heat sink (see thermal derating curves in product series’
datasheet).
Be sure that thermal pad is pre-installed before installing over the heat sink.
EL series SSR mounting slots have a diameter of 0.16 in (4.0 mm). Two screws
are needed (not included) to mount the EL onto heat sink (See fig. 1).
Recommended screw size is 8-32 (UNC standard) or M4 (metric).
Before applying full torque tighten down both screws until they contact the
baseplate. Then, tighten them to 9.0-10.0 in-lb (1.0-1.13 Nm).
For optimal thermal performance heat sink fins should be oriented vertically to
promote natural convection airflow.
