Mounting instructions
FIG. 1: A thin layer of thermally conductive silicone paste must be
evenly applied to the base of the SSR. In case of a thermal pad attached to
the base of the SSR, no thermal paste is required.
FIG. 2: The extrusion length of the heatsink must be long enough to cover
the plastic ribs fins at the back of the SSR to prevent excess mounting torque
from damaging the SSR. The SSR shall be mounted on the heatsink with 2x M5
screws with spring and flat washer. Gradually tighten each screw, alternating
between the two, until both are tightened at 0.75 Nm. Then tighten both screws
to the final mounting torque of 1.5 Nm. In the case of a thermal pad,
gradually tighten (alternating between the 2 screws) to the maximum mounting
torque of 1.5 Nm.
FIG. 3 : The heatsink needs to be mounted in such a way to guarantee best
possible airflow, i.e., with fins in the vertical position.

ATTENTION
Hazardous Voltage can cause death or serious injury. Disconnect power before
proceeding with any work on this equipment. Never touch the terminals of the
relay (SSR) if voltage is present at its terminals. The output terminals
remain live even in the off-state (leakage current, SSR breakdown). Heatsink
may be hot, even after removing the power.
IMPORTANT
Should you require information about installation, operation or maintenance
of the product that is not covered in this instruction document you should
refer the matter to an authorized Carlo Gavazzi representative. The
information in this document is not considered binding on any product
warranty.
- Only authorised and qualified personnel should be allowed to install and perform maintenance on this equipment
- Always use the SSR within its rated specifications and follow provided instructions otherwise malfunction, damage or fire may result
- The relay must be protected against overload (short circuit) by means of an external semiconductor fuse (F1)
- Heat generated by incorrect terminations may result in fire. Ensure the use of proper cable sizes and allow adequate radius of curvature for wire bends
- Loose terminals generate abnormal heat. Tighten to the specified torque. Re-tighten after 48 hours to minimize wire cold flow. Re-torque every 3 – 6 months
- For use in Pollution Degree 2 Environment
- For use in a circuit where devices or system, including filters or air gaps, are used to control overvoltage’s at the maximum rated impulse withstand voltage peak of 2.5 kV on input, 6 kV on output. Devices or system shall be evaluated using the requirements in the Standard for Transient Voltage Surge Suppressors, UL 1449 and shall also withstand the available short circuit current in accordance with UL 1449
- A1, A2 (RL..A) shall be supplied by a secondary circuit where power is limited by a transformer, rectifier, voltage divider, or similar device that derives power from a primary circuit, and where the short-circuit limit between conductors of the secondary circuit or between conductors and ground is 1500 VA or less. The short-circuit volt ampere limit is the product of the open circuit voltage and the short circuit ampere
- This product has been designed for Class A equipment (external filtering may be required). Use of this product in domestic environments may cause radio interference, in which case the user may be required to employ additional mitigation methods
