A.4 Ul certification
The devices are certified as per Ul 508C. For this purpose the following conditions are to
be met by the user:
1. The devices may only be operated in systems of overvoltage category III.
2. The devices are rated for installation in an environment of pollution severity 2.
3. The protective device for branch lines must be executed in accordance with the
manufcturers' instructions, the requirements of the NEC (National Electrical Code)
and other locally applicable standards.
4. Only Ul certificated device connection cables (mains, motor and control cables)
may be used:
− Use copper conductors with a temperature resistance of at least 75 °C (167 °F).
− Specified tightening torques for the terminals:
5. Maximum temperature of the ambient air (surrounding temperature): see
table A.7
6. Multiple rated equipment: For details see tables A.1, A.2 and A.3.
7. Integral solid state short circuit protection does not provide branch circuit
protection. Branch circuit protection must be provided in accordance with the
Manufacturer Instructions, National Electrical Code and any additional local codes.
8. Control outputs (X4/23; X4/24) and OSD00, OSD01, OSD02 (see ratings of control
circuitry): Use secondary isolating source rated 25 V AC, 30 V DC or 24 V DC as
appropriate for rating of the given output. Fuse in accordance with Ul248, rated
100 V must be connected between the source and the output.
9. Suitable for use on a circuit capable of delivering not more than 5000 rms
symmetrical Amperes @ Volts maximum (+240 V maximum for G394-0xx /
+480 Volts maximum for G394-0xx), when protected by class RK5 fuses:
