non-hazardous area. Conform to local wiring codes. When pouring a seal, use a fibre dam to assure proper formation of the seal. Seals should never be poured at temperatures below freezing. The jacket and shielding of the cable should be stripped back to permit the seal to form around the individual wires. This will prevent air, gas and water leakage through the inside of the shield and into the enclosure. It is recommended that explosion-proof drains and conduit breathers be used. In some appl

The ST1210 sensors can be installed and wired directly to the UNI-TRAN Premium Plus housing and terminal board as per the wiring diagram (see Figure 10 ) or they may be remotely mounted using a sensor separation kit (JB2-3-ASSY) which is composed of a junction box and terminal strip (see Figure 11). The sensor and kit are then connected to the UNI-TRAN Premium Plus. When sensor separation is required for units using the ST1210 Hydrogen Sulfide sensor use a minimum of 18AWG shielded copper ins
