1、安全柵應(yīng)安裝在非危險場所。
2、安全柵通往現(xiàn)場(危險場所)的軟銅導(dǎo)線截面積必須大于0.5mm²。
3、連接導(dǎo)線的絕緣強(qiáng)度大于500V。
4、安全柵本安端(有藍(lán)色標(biāo)記)和非本安端電路配線，不得接錯和混淆。本安導(dǎo)線宜選用藍(lán)色作為本安標(biāo)記。本安導(dǎo)線和非本安導(dǎo)線在匯線槽中應(yīng)分開鋪設(shè)，采用各自保護(hù)套管。安全
柵的本安側(cè)，不允許混淆有其它電源，包括其它本安電路的電源。
5、安全柵與一次儀表組成本安安全防爆系統(tǒng)時，必須經(jīng)國家指定的防爆檢驗機(jī)構(gòu)檢驗認(rèn)可。PH系列安全柵安全柵由國家防爆電氣監(jiān)督檢驗中心，給出的Co，Lo分布參數(shù)是相對與ⅡC級(氫氣級)的最大允許值對于ⅡB級環(huán)境可把該參數(shù)乘以3，對于ⅡA級環(huán)境可把該參數(shù)乘以8。傳輸線選用不同規(guī)格的電纜時，其本身的電纜參數(shù)應(yīng)予高度重視，不得超過規(guī)定值。
6、對安全柵進(jìn)行單獨通電調(diào)試時，必須注意安全柵的型號、電源極性、電壓等級及安全柵外殼接線端上的標(biāo)號。
7、嚴(yán)禁用兆歐表測試隔離安全柵端子之間的絕緣性。若要檢查系統(tǒng)線路絕緣性時，應(yīng)先斷開全部安全柵接線，否則會引起內(nèi)部器件損壞。
